Environment

  • Platform9 Managed OpenStack - All versions

  • Nova

  • Libvirt

hashtag
Cause

The libvirt service is not able to setup a TLS connection with the destination host because the certificates were rotated recently. This is an upstream limitation and has been fixed in libvirt v6.2.0.

hashtag
Resolution

  1. Restart the libvirtd service on the destination host where the instance was being migrated.

# sudo service libvirtd restart

hashtag
Additional Information

Starting v6.2.0, the libvirtd service restart will not be needed as per the libvirtrelease notesarrow-up-right.
