Title:
cannot block migrate old style instances libvirt complains
Status in OpenStack Compute (Nova):
Fix Released
Status in OpenStack Compute (nova) grizzly series:
Fix Released
Bug description:
I have recently upgraded from folsom to grizzly. I tried executing a
block migration. This fails with libvirt complaining:
qemuProcessPrepareChardevDevice:2635 : Unable to pre-create chardev
file '/var/lib/nova/instances/instance-000000ae/console.log': No such
file or directory
In the logging of nova I can see nova creates a UUID style directory.
Obviously this does not match where libvirt is looking. Upon failure
"instance disappeared" (which is a very non descriptive error message)
this UUID directory remains and is not cleaned up.
I tracked it down to libvirt_utils.get_instance_path which also takes
"forceold", but this parameter is not used at all anywhere in the
code.
So I see two possibilities: 1) use original path structure or 2) make
libvirt aware that is should use another path
