VDI Migrate Fail

[SchaffnerOnline]

Migrating VM disks from one SR to another SR.

Select the VM that I want to migrate and then goto the "Disk" tab and on the disk, click on the "Migrate VDI". Select the Destination SR and click on "OK". The migration runs to 100% but then errors out at the end.

If I migrate the VM to a new host in the pool along with migrating the Disks to a new SR then it works fine.

Here is the log from when it fails to migrate the VDI only:

@SchaffnerOnline we have the exact same issue.

Can you reproduce the issue with xe CLI?

[SchaffnerOnline]

@olivierlambert ran it from command line and got the same results
