Virtualization Short Take #26, Hyper-V Edition

I’ve been seeing an increasing amount of coverage on Hyper-V, especially with all the hype (sorry, no pun intended) surrounding Windows Server 2008 R2 and the next version of Hyper-V. Kudos to Ben Armstrong aka “Virtual PC Guy”, who pumped out almost all of these articles and is really generating some good content. I don’t want this to be a blatant rip-off of his content, but I did want to share this information with my readers. All the credit goes to Ben!

  • Hyper-V and 3-D graphics in the parent partition apparently don’t mix. There isn’t really a workaround. You can’t really fault Microsoft for this—Hyper-V wasn’t intended to be a high-end graphics workstation.

  • Having problems with a corrupted virtual hard disk? This information may help.

  • If you use Windows Sidebar, you might find the Hyper-V Monitor Gadget handy. I don’t use Windows Sidebar—I don’t even use Windows unless I have to—so I can’t provide any direct feedback on this tool.

  • This blog post has information on how to merge snapshots back into a single VHD.

  • If you’re using Hyper-V on a laptop, I would first ask you, “Why?” Then I would point you to this article by Ben on how to enable/disable the Hyper-V hypervisor so as to allow the laptop to sleep or hibernate. These functions are disabled when the hypervisor is active.

  • Running Windows 7 on Hyper-V works, but creates some spurious event log entries that can be ignored.

  • In this post, Ben provides more information on the upgrade path from Windows Server 2008 to Windows Server 2008 R2, including Hyper-V.

  • Here’s a guide on how to migrate virtual machines from Virtual Server to Hyper-V (link via Ben, again!).

  • Via Ben, if you have a VM running Hyper-V but it’s not showing up under the virtual machine list in the Hyper-V management console, restarting the virtual machine management service (VMMS) will likely correct the problem.

  • For users looking forward to the live migration functionality included in Windows Server 2008 R2, Ben provides a link to this step-by-step guide to setting up live migration. There’s in-depth information on configuring Cluster Shared Volumes (CSV) and setting up the cluster network for live migration.

That does it for now. Again, thanks to Ben Armstrong—and some of the other Microsoft bloggers who didn’t make this list but whom I’ve referenced before—for putting out good information on their virtualization products. Keep up the good work!
