How do I resolve the error:
This operation could not be performed because a VDI is in use by some other operation
I see this when trying to (re)start a stopped VM.
(For Xen 6.2) If you have access to XenCenter go to 'view' 'show hidden' and make sure that there isn't a job running for this VM already. If there is, stop and delete it.
This may happen if you tried to export a VM and it didn't complete (for whatever reason).
Previous answer helped me. the only issue is that the hidden job was stating it was running on another vm - a vm not present in my environment, but shut down and than delete the "transfer vm" did the trick. i was able to power on the faulty vm afterwards
