/.autorelabel is gone. I don't have access to the tty but on the serial console I get: *** Warning -- SELinux targeted policy relabel is required. *** Relabeling could take a very long time, depending on file *** system size and speed of hard drives. So I assume the relabeling is happening. libvirtd is still not happy though. ...Juerg > - Cole >
