@olivierlambert both VM's were in a halted state, but didn't want to initiate the migration until I made a snapshot.
So it is really an AND statement, until phase 3 is rolled out

Struggled to get it to work until someone pointed out that you need a snapshot of the VM first before executing the command.

Running esxi 6.7.0 Update 3 (Build 14320388)

So far only linux vm's transferred without issue.
Don't have a windows VM to test with, will create one and test the migration.

Re: xcp-ng CPU low performance issue

Found the linked issue and it resolved it for one of our other HP (ProLiant DL380p Gen8) hosts, but for some reason selecting OS Controlled or even Maximum Performance doesn't change the Avg freq results for the watch 'xenpm start 1 | grep -i "Avg freq" command.

Currently running XCP-8.1.0 with latest patches (as of writing this)

Every 2.0s: xenpm start 1 | grep -i "Avg freq"Tue Mar  2 21:54:22 2021

Xen Orchestra stats does show it performing though so I'm assuming all is well?

Any advise will be greatly appreciated. Thanks
