Once you download the update from here your MVS 2005 Host will be upgraded to Version 1.1.629.0:
The update also updates your Virtual Machine Additions to Version 13.820 so be prepared to begin getting warnings about all your VMs once you upgrade your HOST. Looking at the VM Additions, it seems like they updated the seven core files/drivers. PER the KB article, the main changes are probably to just add support for Server 2008 and the latest Service Packs for Vista and XP:
So far, I’ve had no issues. I’ve updated about 6 or 7 Guest VMs. I’ve even built a new Windows Server 2008 Enterprise box, and it’s up and running without issues on my old Virtual Server 2005 Host. Yes, yes I know…many of you are wondering “Why does MrGroove care about MVS 2005 when he already has a few Windows Server 2008 Hyper-V Boxes?” BECAUSE, half my VM Hosts that have SICK amounts of memory are running with CPUs that don’t support VT technology. This support is a requirement for Server 2008 Hyper-V. So, with that in mind, I’ll be running MS Virtual Server 2005 until those boxes die or get replaced. KB948515 Details describing ALL the added Guest OS Support: Tags: hyper-v, microsoft-virtual-server, download, kb948515 , virtual-pc-2007-sp1 If you install MS Virtual Server 2005 R2 Sp1 w/all the updates on a x64 HOST, you should have no problem installing x64 guest systems. Just make sure you have all the latest updates and you install the x64 version of the Virtual Server App. Comment
