I'm not entirely sure why Libvirt is checking to see if the target file exists for LVM but it is a problem. Empty volume groups do not appear in /dev. When libvirt starts these pools then fail to autostart because their path does not exist. This is not useful, this is the patch we are running to resolve this issue.

The patch makes sense, but it's missing SoB line which is required per https://libvirt.org/hacking.html#patches point 6. I can polish the commit message a bit and add your SoB if you reply to this e-mail with it.

BTW: how did you send the patch? It's base64 encoded and git-am can't apply it.
