[VDDK V2V] Migration of VM that had more than 1 snapshot creates multiple VHDs

MajorP93

Dear Vates team and community,

I am currently in the process of migrating our whole internal VMWare infrastructure to XCP-ng / Xen Orchestra.

I am using the new VDDK based V2V tool for this matter.

I noticed that when having more than 1 snapshot for a VM on the VMWare side the V2V tool will create multiple VHDs even though the VM only has 1 virtual disk on the VMWare side.

After migration the disk layout of the VM looks like this:

My question is: is it possible to merge these into 1 single VHD so the disk layout matches the one of the VMWare side?

And: is it possible to have 2 snapshots per VM on VMWare side and prevent this from happening so that the resulting XCP-ng VM only has 1 VHD per VMWare VMDK?

Thanks a lot in advance!

Best regards
MajorP

@MajorP93 the size are different between the disks, did you modify it since the snapshots ?

would it be possible to take one new snapshot with the same disk structure ?

Sorry it was my bad indeed.
On the VMWare side there are 2 VMs that have almost the exact same name.
When I checked for disk layout to verify this was an issue I looked at the wrong VM.

I checked again and can confirm that the VM in question has 1x 60GiB and 1x 25GiB VMDK.

So this is not an issue. It is working as intended.

Sorry again and thanks for the replies.

@MajorP93 in your screenshot, CA and CA_1 seems to be two disks on the original VM... ?

They're even different in size.

each are suffixed with -000001-delta, indicating one snapshot, on each disk

two vmdk on source gives you two vdis on destination, as intended

Thanks for your reply.

The VM only has 1 virtual disk (60GB) on VMWare side.
Otherwise the situation would be clear and I would not have asked the question

@MajorP93 stress of VM migration XD

good luck with your V2Vs !
