What do you mean by "fails"? What is the failing operation (move disk when vm is running or not?) and how does it fail? ... > It appears that the VM fails to start on the new host, but it's not > obvious why from the logs. Can anyone shed some light or suggest further > debugging? You move the disk when the vm is not running, and after the move the vm will not start? If this is the issue, you can check if the disk was copied correctly by creating a checksum of the disk before the move and after the move. Here is example run from my system: $ cat ~/.config/ovirt.conf [myengine] engine_url = https://engine-dev username = admin@internal password = mypassword cafile = /etc/pki/vdsm/certs/cacert.pem $ python3 /usr/share/doc/python3-ovirt-engine-sdk4/examples/checksum_disk.py -c myengine 3649d84b-6f35-4314-900a-5e8024e3905c { "algorithm": "blake2b", "block_size": 4194304, "checksum": "d92a2491f797c148e9a6c90830ed7bd2f471099a70e931f7dd9d86853d650ece" } See https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/checksum_disk.py Nir _______________________________________________ Users mailing list -- [email protected] To unsubscribe send an email to [email protected] Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/[email protected]/message/KLD5NMFNJGBXEXUPVQCD4BHQXZXO4RHF/
