Hyper-V problem.

[ZaForD]

Hi Guys,

I've got a problem with some of the .VHD's in Hyper-V.
I added a bigger HDD to use exclusively with Hyper-V, I moved all the .VHD files to an external drive, added the new HDD, setup Hyper-V to use the new HDD and moved all the VHD's back, everything appeared to go fine. :)

But now i've noticed two of my .VHD's won't load, I get an 'access denied' error. I've looked at the permissions on the .VHD's and there are some users missing (one with a load of numbers and one named Virtual Machines) on the two non-working files. Neither of these users are listed on my machine so I can't add the permissions.

Anybody got, any ideas.

Thanks.

Remove those owners and take ownership of the drive by going into properties and then advanced and in there under Owner, overwrite existing owner, hope that helps

below solution come from microsoft.

1. remove your VM from hyper-v, remain the VHD
2. recreate VM, but use old VHD.

COMPLETE!

very stupid official solution, but WORK! :D

Hi Kingwilliam,
Your right, it is stupid.
And even if it does work, its certainly not a 'solution' :(

If (like me) you had any 'Snapshots' or where using 'Differencing Disks' this 'solution' is useless. :mad:

MS had better find a real solution soon.
As 'XP Mode' in Windows 7 is based on 'Differencing Disks' so this likely to happen alot more offen. :eek:
