SCVMM Bare-Metal Fails

Add drivers to SCVMM Bare-Metal WinPE Image

A long time ago I wrote a blog post on how you can use System Center Virtual Machine Manager Bare-Metal Deployment to deploy new Hyper-V hosts. Normally this works fine but if you have newer hardware, your Windows Server Image does may not include the network adapter drivers. Now this isn’t a huge problem since you can mount and insert the drivers in the VHD or VHDX file for the Windows Server Hyper-V image. But if you forget to update the WinPE file from Virtual Machine Manager your deployment will fails, since the WinPE image has not network drivers included it won’t able to connect to the VMM Library or any other server.

You will end up in the following error and your deployment will timeout on the following screen:

“Synchronizing Time with Server”

SCVMM Bare-Metal Fails

If you check the IP configuration with ipconfig you will see that there are no network adapters available. This means you have to update your SCVMM WinPE image.

First of all you have to copy the SCVMM WinPE image. You can find this wim file on your WDS (Windows Deployment) PXE Server in the following location E:\RemoteInstall\DCMgr\Boot\WIndows\Images (Probably your setup has another drive letter.

WDS SCVMM Boot WIM

I copied this file to the C:\temp folder on my System Center Virtual Machine Manager server. I also copied the extracted drivers to the C:\Drivers folder.

After you have done this, you can use Greg Casanza’s (Microsoft) SCVMM Windows PE driver injection script, which will add the drivers to the WinPE Image (Boot.wim) and will publish this new boot.wim to all your WDS servers. I also rewrote the script I got from using drivers in the VMM Library to use drivers from a folder.

Update SCVMM WinPE

This will add the drivers to the Boot.wim file and publish it to the WDS servers.

Update WDS Server

After this is done the Boot.wim will work with your new drivers.

Azure Site Recovery

Microsoft Azure Site Recovery Preview

Microsoft today announced the preview of Disaster Recovery to Azure called Microsoft Azure Site Recovery. This also replaces HRM (Hyper-V Recovery Manager). Microsoft Azure Site Recovery (ASR) allows you to orchestrate disaster recovery to a second site or directly to Azure.

Microsoft ASR

Both solutions use Microsoft on-prem technology like Windows Server Hyper-V Replica and System Center Virtual Machine Manager and you can start using them via the Microsoft Azure Management Portal.

In addition to enabling Microsoft Azure as a DR site in multiple geographies, this preview also includes an impressive list of features for enabling virtual machine replication to Azure:

  • At-Scale Configuration
    You can configure the protection and replication of VM settings in a private cloud and configure and connect on-prem networks with Azure Networks. Those VM’s are then only replicated to customer-owned and managed geo-redundant Azure Storage.
  • Variable Recovery Point Objective (RPO)
    This feature provides support for near-synchronous data replication with RPOs as low as 30 seconds. You can also retain consistent snapshots at desired frequency for a 24-hour window.
  • Data Encryption
    VM Virtual Hard Disks can be encrypted at rest using a secure, customer-managed encryption key that ensures best-in-class security and privacy for your application data when it is replicating to Azure. This encryption key is known only to the customer and it is needed for the failover of VM’s to Azure. Simply put: All of this service’s traffic within Azure is encrypted.
  • Self-Service Disaster Recovery
    With ASR you get full support for DR drills via test failover, planned failover with a zero-data loss, unplanned failover, and failback.
  • One-Click Orchestration
    ASR also provides easy-to-create, customizable Recovery Plans to ensure one-click failovers and failbacks that are always accurate, consistent, and help you achieve your Recovery Time Objective (RTO) goals.
  • Audit and Compliance Reporting with Reliable Recovery
    DR testing and drills can be performed without any impact to production workloads. This means you get risk-free, high-confidence testing that meets your compliance objectives. You can run these non-disruptive test failovers whenever you like, as often as you like. Also, with the ability to generate reports for every activity performed using the service, you can meet all your audit requirements.

ASR does not only help you in terms of Disaster Recovery, it also allows you to quickly and easily migrate your Virtual Machines to Azure or create a new dev environment.

Check out the ASR session at TechEd 2014 and Brad Andersons blog about the release of the Azure Site Recovery Preview.

Once you’re ready to see what ASR can do for you, you can check out pricing information, sign up for a free trial, or learn more about the product specs.

Savision Whitepaper

Whitepaper and Webinar “VMM (fabric) Management and Resource Pooling”

One of the most challenging things during the shift to Cloud Computing is to manage Fabric Resources efficiently. Together with Savision I have worked on a whitepaper in which it is outlined how Fabric resource like Compute, Storage and Network can be managed efficiently and how System Center Virtual Machine Manager provides a solution to build a datacenter abstraction layer.

The whitepaper is focused on building a datacenter abstraction layer of your fabric resources, self-service and service deployment. If you would like to know more about it, join our webinar.

Hyper-V Network Virtualization NVGRE: No connection between VMs on different Hyper-V Hosts

I have worked on some project with Hyper-V Network Virtualization and NVGRE, and today I have seen an issue with Encapsulated Task Offloading on some HP Broadcom Network adapters.

 

Issue

I have Hyper-V Hosts running with 10GbE Broadcom Network Adapters (HP Ethernet 10Gb 2-port 530FLR-SFP+ Adapter) with driver version 7.8.52.0 (released in 2014). I have created a new VM Network based on Hyper-V Network Virtualization using NVGRE. VM1 is running on Host1 and VM2 is running on Host2. You can ping VM2 from VM1 but there is no other connection possible like SMB, RDP, HTTP or DNS. If you are using a NVGRE Gateway you can no even resolve DNS inside those VMs. If VM1 and VM2 are running on the same Hyper-V host everything between those VMs works fine.

Advanced Driver Settings

If you are using Server Core, which you should by the way, you can use the following command to check for those settings:

PowerShell NetAdpater Advanced Property

 

Resolution

The Broadcom Network adapters have a feature called Encapsulated Task Offloading which is enabled by default. If you disable Encapsulated Task Offloading everything works fine. You can disable it by using the following PowerShell cmdlet.

After that connection inside the VMs started to work immediately, no reboot needed.



Savision Cloud Advisor VMM Tuning Tips

Cloud Advisor for System Center Virtual Machine Manager

As you may know I do a lot of work around Hyper-V, System Center and Windows Azure Pack. One of the most critical parts of the Microsoft Cloud is System Center Virtual Machine Manager. VMM is the component where mostly everything comes together in some way. From the Fabric resource such as Storage, Compute and Networking up to the Virtual Machines and Services running on top of the Fabric layer. Virtual Machine Manager basically allows you to pool resources and offer them to tenants which can than deploy services and virtual machines to the pools.

This means VMM manages not only your Virtual Machines, Virtual Machine Manager also manages your network environment, your storage and a lot more. So wouldn’t it be great to use the data Virtual Machine Manager collects to review your environment and get some tips you can optimize it? This is exactly what Savision did with their Virtual Machine Manager Add-in called Cloud Advisor which includes tuning and optimization recommendations.

Savision’s Cloud Advisor looks for problems like:

  • “Virtual Machine Appears to be Unused”
  • “Prediction: All Available Memory Will Be Consumed By…”
  • “Virtual Guest Services Are Not Installed”
  • “Starting Memory Is Too High”
  • “Low Disk Space On Cluster Shared Volume”
  • “Dynamic Memory is not enabled”
  • and a lot more…

Most of you will think okay, this sounds great but how much will this thing cost. Well that’s the great part, the Savision Cloud Advisor for System Center Virtual Machine Manager is absolutely free. So there is absolutely no reason why you shouldn’t deploy the Savision Cloud Advisor in your Virtual Machine Manager environment.

Simply go the Savision homepage, download the Cloud Advisor and import it to VMM.

Import Cloud Advisor Addin into VMM

After that you will have to connect to the VMM database and to let the Savision Cloud Advisor his job, showing you tips and recommendations for your environment.
