Virtual machine crashed while migrating to a new host

Solution Verified - Updated -


  • The live migrate procedure fails.

    # virsh migrate test-vm qemu+ssh://test-destination-host/system
  • The VM showed up temporary on the destination server but disappeared.

  • During the migration the VM crashed and it looks like qemu-kvm crashed while starting the VM.
  • The libvirt/qemu log file for the VM that crashed. Lines below show when the crash occurred.
