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.

[abudef]

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...
