Lost image on reboot - Re: Solved - Re: F38 - QEMM image migration problem

[Robert Moskowitz <rgm@xxxxxxxxxxxxxxx>]

Just did a reboot.  After 2 kernel updates and what looks like a qemm 
update last night.

QEMM is not showing any available virtual machines.

What do I do?  The create below?  Again?

thanks
