State blocked by non-migratable CPU device

[dannybridi]

Hello,
When live-migrating a VM from one node to another, I get the following error message at the end of the copy process:
online migrate failure - VM 110 qmp command ‘migrate’ failed - State blocked by non migratable cpu device (invtsc flag)
This only happens on this VM. All others live-migrate without issues.
Any ideas why?
I have a 3-node cluster running PVE 8.0.4
Thanks

Plugging an error message into google often leads to helpful information, ie https://bugzilla.redhat.com/show_bug.cgi?id=1254124

You should examine your VM configurations, ie "qm config 110" vs "qm config [vmid_that_works]", perhaps removing the flag from the configuration is an easy solution.

Thanks bbgeek17. I actually did first search Google, but did not find anything. The link you specified did help. Thanks. now I know that what I’m looking for is a flag in the confit file. Next step is to learn what these flags are
