Hyper-V Program Manager
A little while ago I published a number of posts discussing the process I used to move my virtual machines from using dynamically expanding virtual hard disks to using fixed-size virtual hard disks. There were some interesting questions / discussions in the comments – so I thought I would try to sum them up here:
The last time i tried to enlarge a fixed vhd (exchange database disk) i did exactly as described (shut down, expand, resize partition in guest) but afterwards the disk was empty...?
This was anyhow a good method to test the recovery from our backup, but still more than a little annoying...
I have no idea why that would have happened. I promise that I manually followed these steps before posting :-)
Don't you think fixed size VHD with Undo disks enabled would have been more appropriate for the XP Mode Base VHD than using a differencing VHD? That way users would have had an easy option to give lots more free disk space to the XP Mode VHD, great performance and the differencing VHD not expanding like crazy.
I use dynamic to keep BackupExec hyper-v backups small. Am I missing something or do all products transfer the entire vhd before compression?
Sorry for the dumb question but...
i use several VHD on Win7, basically one for each client's setup. Where do i access the Virtual Machine settings? My VHD's are on my C:/ Drive.
Thanks for your help
@XPclient, how would having undo drives allow the end user more free space (the max you can go is 127GB with VPC regardless of differening or undo drives) and instead of your diff drive expanding, your undo drive would. Plus, how do you deal with the end-users that inadvertently discard their undo drives losing all their data? That would be a huge problem for PSS.
@Daniel, how did you create these VMs? The settings are in the same folder ( %userprofile%\virtual machines ) as the menu for creating a new VM.
