Hyper-V vNext Runtime Memory Resize

Sneak Peek into the Next Version of Hyper-V

Back in October Microsoft released the first public Windows Server Technical Preview for the next release of Windows Server. At TechEd Europe Bed Armstrong, Principal Program Manager on the Hyper-V team at Microsoft, talked about a couple of new features which are coming in the next release of Windows Server Hyper-V. This is a quick list of some of the new features we will get in the next release of Windows Server Hyper-V, there is a lot more coming until the release of Windows Server vNext and System Center vNext in 2016.

Virtual Machine Configuration Changes

Hyper-V vNext VM Configuration Files

In the next release of Hyper-V Microsoft will change the Virtual Machine configuration files. Today the Hyper-V VM configuration files had the xml file format. You were able to open the file and check and edit the virtual machine configuration inside that file, even it was never supported. By running more and more workloads virtual and in a dynamic cloud way, scale and performance gets even more critical. In the next version of Hyper-V Microsoft will change the VM configuration from the xml file to a binary file format. The new binary format brings more efficient performance at large scale. Microsoft also now includes a resilient logging for changes in the configuration files so this should protect virtual machines from corruption.

New file extensions:

  • .VMCX (Virtual Machine Configuration) – replaces the .xml file
  • .VMRS (Virtual Machine Runtime State) – replaces .bin and .vsv file

Production VM Checkpoints (Snapshots)

Hyper-V vNext Production CheckPoint

Virtual Machine Checkpoints or in older versions Virtual Machine Snapshots were a great solution to take a state of a virtual machine and save it, doing some changes and if something fails you could simply revert back to the time you took the checkpoint. This was not really supported to use in production, since a lot of applications couldn’t handle that process. Microsoft now changed that behavior now fully supports it in production environments. For this Production Checkpoints are now using VSS instead of the Saved State to create the checkpoint. This means if you are restoring a checkpoint this is just like restoring a system from a backup. For the user everything works as before and there is no difference in how you have to take the checkpoint. Production Checkpoints are enabled by default, but you can change back to the old behavior if you need to. But still using Checkpoints brings some other challenges, like the growing .avhdx file, which still apply.

Hyper-V Replica support for Hot Add of VHDX

Hyper-V Replica was one of the greatest new features in Windows Server 2012 Hyper-V. In Windows Server 2012 and Windows Server 2012 R2 Hyper-V, if you have hot added a VHDX file to a Virtual Machine, replication failed. In the next version of Hyper-V when you add a new virtual hard disk to a virtual machine that is being replicated, it is automatically added to the not-replicated set so replication continues to run and you can then online update this set with via PowerShell and the VM will automatically resynchronize and everything works as expected.

Hot add / remove of Virtual Machine Memory

Hyper-V vNext Runtime Memory Resize

In Windows Server 2012 R2 Hyper-V you could decrease the Minimum Memory and increase the Maximum Memory of a Virtual Machine using Dynamic Memory while the VM was running. In the next version of Hyper-V you can now increase and decrease the Memory assigned to virtual machines while they are running, even if they are using static memory.

Hot add / remove of virtual network adapters

Hyper-V vNext Hot Add and Remove Virtual Network Adapters

This was maybe the feature VMware fan boys all over the world have used against Hyper-V. However I didn’t really saw a lot of customers doing this, but it is great that you can now hot add and remove network adapters from Virtual Machines.

Virtual Network Adapter Identification

Hyper-V vNext Virtual Network Adapter Identification

For me more important than hot add or remove virtual network adapters is this feature. When dealing with automation you are always happy you can identify different network adapters. For the Hyper-V hosts we have different solutions such as Consistent Device Naming (CDN), sort by PCI slot using PowerShell and other options to identify network adapters. But we didn’t really have a great solution for Virtual Machines. With Network Adapter Identification this changes. You can name individual virtual network adapters in the virtual machine settings and see the same name inside the guest virtual machine.

PowerShell on the Hyper-V Host

PowerShell in the guest

Hyper-V Manager Improvements

Finally, this is something which is not a problem in most environments , since we know how things work. But a lot of people which are Hyper-V beginners coming from VMware or other platforms, they have some simple troubles with Hyper-V Manager. In the next version there are a couple of create improvements which make things a lot easier.

  • Hyper-V Manager is now connecting via WinRM instead of WMI
  • Support for alternate credentials (Requires that you have CredSSP enabled on the server and client)
  • Connected to Hyper-V Hosts via IP address
  • Mange Windows Server 2012 Hyper-V, Windows Server 2012 R2 Hyper-V and the next version of Hyper-V from the latest console

Power Management improvements

SleepStudy Report Connected Standby Transitions

Microsoft updated the hypervisor power management model to support new modes of power management. And this is one of the reasons I run Windows 10 Technical Preview on my Surface Pro 3. Surface Pro 3 is a device which can run Connected Standby, but if you install Hyper-V on Windows 8.1 Connected Standby stops working. In the next version of Hyper-V Connected Standby will work.

Rolling Cluster Upgrade

Hyper-V vNext Rolling Cluster Upgrades

With this new feature you are finally able to upgrade a Hyper-V Cluster from Windows Server 2012 R2 Hyper-V to the next version of Hyper-V without new hardware, no downtime and the ability to roll-back safely if needed. In Windows Server 2012 R2 you had to create a new Hyper-V Cluster while the old Hyper-V Cluster was still running and migrate a Hyper-V Cluster via Cluster Migration Wizard or Live Migration. You can now have Windows Server 2012 R2 Hyper-V Hosts and the next version of Hyper-V running in the same Hyper-V Cluster. To make this scenario possible, the Hyper-V team had to do some changes to the Virtual Machine Upgrade Process

New Virtual Machine Upgrade Process

Hyper-V vNext Update VM Configuration Version

To support Rolling Cluster Upgrades Microsoft had to make some changes to the Virtual Machine Upgrade Process. In the current versions of Hyper-V, Virtual Machines were automatically upgraded from the old to the new version, which means that if you once moved a Virtual Machine to a new Hyper-V host you couldn’t move it back again. In a mixed cluster environment this does not work. In the next version of Hyper-V, Virtual Machines will not be upgraded automatically. Upgrading a virtual machines is a manual operation that is separate from upgrading the Hyper-V host. This allows you to move virtual machines back to earlier version of Hyper-V until they have been manually upgraded.

New way how VM Drivers (integration services) get updated

Since Windows Server 2012 R2 Hyper-V, VM drivers (integration services) were updated with each new host release, and it was required that the VM driver version matches the host version. When new Hyper-V integration services were shipped you had to update the Hyper-V host and form there you could upgrade the VM drivers inside the virtual machine. With Windows Server vNext Hyper-V Microsoft brings VM driver updates over Windows Update. This means also that you now don’t have to have the VM integration services matching the host version, you simply need the latest version of the integration services released.

Secure Boot Support for Linux

Microsoft is pushing hard to bring more and more supported for Linux operating systems such as dynamic memory and other features. With Hyper-V vNext Microsoft bring Secure Boot support for Linux which works with Ubuntu 14.04 (and later) and SUSE Linux Enterprise Server 12.

PowerShell to enable Secure Boot Support for Linux:

Distributed Storage QoS

Hyper-V vNext Storage QoS

In Windows Server 2012 R2 Hyper-V we got the possibility to limit maximum IOPs for an individual virtual hard disk which was a great feature. Everything worked great when you were running the Virtual Machine on a single Hyper-V host, but when you were running multiple Hyper-V hosts with multiple Virtual Machine against the same storage, the Hyper-V host didn’t know that he had to compete with other servers for Storage IOPs or bandwidth. For example the scenario of a minimum IOPs setting did only work on standalone Hyper-V servers. With the next release of Hyper-V and Windows Server Microsoft adds a lot of new stuff. Together with the Scale-Out File Server and Storage Spaces, Microsoft now allows you to define IOPs reservation for important virtual hard disks and a IOPs reserve and limit that is shared by a group of virtual machines / virtual hard disks. This intelligence, build by Microsoft Research, enables a couple of interesting scenarios especially in service provider environments and large scale enterprises.

Virtual Machine Compute Resiliency

Hyper-V vNext Compute VM Reciliency

Microsoft invested heavily into VM resiliency, especially to hardware failure. One of them is the VM Compute Resiliency feature. This feature allows Virtual Machines to run on a host even if the cluster node is not available to the other nodes in the cluster. For example in Windows Server 2012 R2, if the cluster service couldn’t reach the node in the cluster for 30 seconds, the cluster would failover all the virtual machines to another node. If the same things happens in Windows Server vNext Hyper-V, the node would go into isolated mode for the next 4 minutes (default setting) and when the node comes back in four minutes all the virtual machines will still be running. If it doesn’t come back within four minutes the VMs will failover to another node. If a node is flapping from Isolated Mode to running the cluster service will set the node to quarantined and will move all the virtual machines from the node to another node. This should help keep your workloads running even if there are some hardware or network failures.

Evolving Hyper-V Backup

If you are working in IT you know that Backup is always a issues. And things didn’t really get better by running Virtual Machines running on Storage Systems. With the next release of Hyper-V Server Microsoft will release a completely new architecture to improve reliability, scale and performance of Virtual Machine backups. There are three big changes in the backup architecture:

  • Decoupling backing up virtual machines from backing up the underlying storage.
  • No longer dependent on hardware snapshots for core backup functionality, but still able to take advantage of hardware capabilities when they are present.
  • Built in change tracking for Backup of Virtual Machines

RemoteFX

Microsoft also did some improvements on RemoteFX which now includes support for OpenGL 4.4 and OpenCL 1.1 API. It also allows you to use larger dedicated VRAM and VRAM in now finally configurable.

Hyper-V Cluster Management

This is maybe something you will never use by yourself but there is another great improvements in terms of automation and development. If you have ever used WMI against a Hyper-V Cluster you always had to run it against every Hyper-V Host in the cluster to get all the information. In the next version of Hyper-V you can finally run WMI against Hyper-V Cluster and it will handle it as it would be a single Hyper-V host, so you get all the information from all hosts in the cluster.

This was a quick overview over just some of the feature and improvements which are coming in the next release of Windows Server Hyper-V which will be released in 2016. There will be much more coming until Microsoft officially releases the next version of Hyper-V and of course some of the stuff I wrote about will be improved as well.

If you want to know more about the next version of Hyper-V checkout Ben Armstrong’s TechEd Europe session or visit some of our TechNet events.

 



Microsoft KiPi

Microsoft Learning: Know it. Prove it. Challenge for Hybrid Cloud

Some weeks ago I passed Microsoft Exam 70-533 Implementing Microsoft Azure Infrastructure Solutions which means I am now Microsoft Certified on Microsoft Azure technology. Microsoft has just lunched a new certification challenge called Know it. Prove it. which leverages free resources at the Microsoft Virtual Academy and take  Microsoft exams afterwards.

A few things about the challenge:

  • There are 8 different learning tracks, ranging from Cloud Development over Web Development to Hybrid Cloud or Office 365.
  • Each track consists of a learning module which is accessible from anywhere so learners can watch video tutorials and do assessments whenever is easy!
  • During KiPi, learners can track their progress, earn badges and points, compete against other challenges, and share experiences with others who are participating.
  • Although the challenge officially kicked off on February 1st, it’s not too late to get started.
  • The “Know It” portion of the challenge runs all of February and the “Prove It” part (i.e. get certified) will start March 1st and end on March 31st

For all Virtualization and Cloud Architects and Engineers this makes really sense to prepare what is coming next for Microsoft Cloud or Windows Server as well as System Center and Hyper-V. So checkout the the Know it. Prove it. challenge on the Microsoft Virtual Academy.

Update Rollup 5 for System Center 2012 R2

Summary: Update Rollup 5 for System Center 2012 R2 and Azure Pack now available

Yesterday Microsoft released a new Update Rollup for System Center 2012 R2 and Azure Pack called Update Rollup 5. Update Rollup 5 has a lot of fixes and new features especially for Windows Azure Pack and System Center Virtual Machine Manager and Data Protection Manager.

Components that are fixed in this update rollup

  • Data Protection Manager (KB3021791)
    • Protect SharePoint with SQL Always on Configuration
    • Protect SharePoint Server, Exchange Server, and Windows Client workloads to Microsoft Azure by using Data Protection Manager
    • Support for multiple retention ranges for long-term backup on Microsoft Azure
    • Ability to transfer initial backup copy offline to Azure
    • Support for protecting Microsoft workloads that are hosted in VMware
    • Display missed SLA alerts on the Data Protection Manager console
    • Enhanced reporting with Data Protection Manager central console
  • Operations Manager (KB3023138)
  • Service Manager (KB3009517)
  • Virtual Machine Manager (KB3023195)
    • Differencing disk as an option in the Windows Azure Pack VMRole deployment
    • New operating system support
    • New ExplicitRevokeRequired parameter to control IP address management when Grant-SCIPAddress is used
    • Support for SQL Server 2014
    • Azure Site Recovery
  • Windows Azure Pack (KB3023209)
    • Adds support for SQL Governor in the SQL Server Resource Provider.
    • Adds administrator support for disabling native Network RP to allow for third-party network provider
    • Provides detail on Virtual Machine Memory type, Memory Startup and Maximum values in the Tenant Portal.
    • Fix to the Get-MgmtSvcRelyingPartySettings PowerShell cmdlet.
    • Fix to the issue of failing to establish Remote Desktop Connection to virtual machines put behind a Network Address Translation (NAT) device.
    • Fix to the Attached Network dialog box where the network entries in the list were disabled.

As you can see you get several new feature with Update Rollup 5. In Data Protection Manager you finally get support for SharePoint, Exchange and Windows Client workload protection to Microsoft Azure, and support for workloads running on VMware infrastructure. Virtual Machines Manager not only brings new features such as support for the Virtual Machine Manager Database to run on SQL Server 2014 it also includes a lot of fixes and a security update (3035898
MS15-017: Vulnerability in Virtual Machine Manager could allow elevation of privilege: February 10, 2015). Some of the most interesting fixes for me are:

  • DHCP extension: Currently, users have to manually update the DHCP extension after update rollup installation on all hosts. This is now automated. After the DHCP extension is replaced in the Virtual Machine Manager server’s installation folder to the latest version, Virtual Machine Manager automatically checks the DHCP extension against all hosts. If the host has an older version of DHCP extensions, the agent version status will be displayed as “DHCP extension needs to be updated in host properties on the Status page.” The user calls the update agent and updates the DHCP extension on the Hyper-V host in the same way that the user did this for the Virtual Machine Manager agent. Also, if the VSwitch is a logical switch, the status will be shown in “logical switch compliance.” The user can remediate the logical switch. This will also update the DHCP extension on the host.
  • Bare-Metal Deployment: If a physical computer profile is created by using vNic (and by using a virtual machine network) and if there are more than one hostgroup for a logical network that also has that virtual machine network when you add a host resource on the “Provisioning Options” page, the host profile will be displayed for only one host group. The profile won’t be displayed for the rest of the host groups.

For Windows Azure Pack also includes some important fixes and improvements on of the is in the Tenant Portal, users can now see details on Virtual Machine Memory type, Memory Startup and Maximum values.

Update Rollup 5 for System Center 2012 R2 brings a lot of new features and important fixes to the table, however before deploying the fixes in your production environment, I recommend to test the Update Rollup and maybe wait for some reports about issues from other users.

InstantGo powercfg

Troubleshoot Windows InstantGo (Connected Standby)

In Windows 8 Microsoft released a feature called InstantGo (formerly know as Connected Standby) which should bring smartphone like Power Management features to your Windows tablet or notebook. Devices such as the Surface Pro 3 do offer this feature. This post should help you troubleshoot issues with InstantGo or Connected Standby.

InstantGo requires the following:

  • Windows 8.1 Operating System (In Windows 8 this is called Connected Standby)
  • A firmware flag indicating support for the standard
  • The boot volume must run on a SSD disk
  • Support for NDIS 6.30 by all network devices
  • Passive cooling on standby
  • Secure Boot
  • Memory to be soldered to the motherboard
  • The Hyper-V Hypervisor role must be disabled on Windows 8 and Windows 8.1 systems. Windows 10 Hyper-V will allow you to use Hyper-V and InstantGo at the same time.

Check if the hardware supports InstantGo

To check if your hardware supports InstantGo you can run the following command:

InstantGo powercfg

InstantGo Issues / Connected Standby Issues

In some case you can run in some issues where you have your battery draining more than expected during the InstantGo or Connected Standby time. This could be of the following reasons:

  • Drivers – Make sure you have the latest drivers installed
  • Firmware – Make sure you have the latest Firmware (BIOS) installed
  • Mails –  The Windows communication app keeps the broker infrastructure (BI) system active. BI, in turn, keeps the WLAN network up so that the system stays up-to-date with emails. If you get a lot of emails this can end up in a higher power drain.
  • Software –  Some installed legacy Software which does not let you go into the InstantGo modus.
  • VPN Clients – Some older VPN Clients can also cause issues with InstantGo
  • Network Activity – The WLAN device might have a challenging radio environment and the Windows system might not be able to establish a reliable Internet connection. We see how these events affect the WLAN device, which, in turn, impacts the battery.
  • Hyper-V – If you run Hyper-V in Windows 8 or Windows 8.1 you can not run InstantGo, this is solved in Windows 10.

Troubleshooting InstantGo / Troubleshooting Connected Standby

To get some more information about your device and InstantGo or Connected Standby you can use the following tools and reports.

powercfg /SleepStudy

Powercfg SleepStudy

The maybe best way to Troubleshoot Connected Standby or InstantGo issues, is to use the powercfg /SleepStudy command. This will generate a Sleep Study report which allows you to analyze different things about Conncted Standby:

Connected Standby / InstantGo Overview

SleepStudy Report

Connected Standby Transitions

SleepStudy Report Connected Standby Transitions

Connected Standby Sessions

Here you can analyze which application or driver did use battery resources during the Connected Standby session.

SleepStudy Report InstantGo

powercfg /batteryreport

powercfg batteryreport

With powercfg /batteryreport you can generate a report about how your battery is used.

Battery Report

And you can also see what kind of state drained your battery, if this was an active session or a Connected Standby session.

Battery Report Battery Usage

powercfg /energy

PowerCFG Engery

With powercfg /engery you can see not only InstantGo or Connected Standby issues, you can see what other applications, drivers and more does could drain your battery.

Energy Report

I hope this helps you to troubleshoot Connected Standby issues.

DPM Deduplication

Deduplication in System Center Data Protection Manager

Today Microsoft announced support for Deduplication in System Center Data Protection Manager (DPM). To use Deduplication together with System Center Data Protection Manager you have to meet the following criteria:

  • The Server running System Center Data Protection Manager must be virtualized.
  • DPM Server has to use Windows Sevrer 2012 R2
  • The Hyper-V Sever where the DPM VM is running on has to be Windows Server 2012 R2
  • System Center Data Protection Manager must be version 2012 R2 with Update Rollup 4 (UR4) or higher.
  • The Data Storage of the DPM Server must be VHDX Files attached to the DPM VM.
  • DPM VHDX files need to be 1TB of size.
  • The VHDX files of the DPM Server must be stored on a Scale-Out File Server Cluster using SMB 3.0
  • All the Windows File Server nodes on which DPM virtual hard disks reside and on which deduplication will be enabled must be running Windows Server 2012 R2 with Update Rollup November 2014.
  • Deduplication is enabled on the CSV of the Scale-Out File Server
  • It is recommended to use Storage Spaces but it is not required
  • Use Parity Storage Spaces with enclosure-awareness for resiliency and increased disk utilization.
  • Format NTFS with 64 KB allocation units and large file record segments to work better with dedup use of sparse files.
  • In the hardware configuration above the recommended volume size is 7.2TB volumes.
  • Plan and set up DPM and deduplication scheduling
  • Tune the File Server Cluster for DPM Storage

DPM Deduplication

The combination of deduplication and DPM provides substantial space savings. This allows higher retention rates, more frequent backups, and better TCO for the DPM deployment. The guidance and recommendations in this document should provide you with the tools and knowledge to configure deduplication for DPM storage and see the benefits for yourself in your own deployment.

To get more information checkout the following TechNet Article: Deduplicating DPM storage
