Cannot import VHD disks while VMDK can

abudef

Hello, I cannot import a VHD with the following error:

When I click on Show logs, there is no entry related to this in the Logs area.

Using qemu-img I converted the VHD to VMDK and it is now importing normally:

Tested with XO commit 07024 and XOA 5.96.0

Good news is Hyper-V can convert this to a dynamic disk, or at least it could, has been a minute since I've done it myself lol. If you edit the VHD in Hyper-V, you can select Convert, then VHD (don't use VHDX), and then select Dynamic.

Hi,

Maybe your VHD was not in the sparse format.

I'm not quite sure what you mean. The disk can be used in Hyper-V and VirtualBox without any problems. Are there any special requirements for imported VHDs?

olivierlambert

Yes, the VHD needs to by dynamic, not static.

I see. It's a pre-allocated disk image. Thank you for the explanation.

olivierlambert

Yes, that's the problem. See https://docs.xcp-ng.org/installation/migrate-to-xcp-ng/#-from-hyper-v

Oh, yeah, I missed that somehow... I looked it up in the Xen Orchestra documentation...
