This has to do with libvirt now running VMs as the unprivileged 'qemu' user. Probably a result of not being able to set an selinux label on the media. You might be able to work around it by temporarily disabling selinux with 'getenforce 0' I also tried using the actual RHEL 5.5 and 5.4 > CD's that I have to install from, but even though it's mounted and I > can view the contents in Nautilus, virt-manager says that /dev/sr0 has > no media present. > I believe F13 doesn't do CDROM media polling by default anymore. On F12 at least this can be changed with: hal-disable-polling --device /dev/sr0 --enable-polling There is also a virt-manager fix upstream to allow using a CDROM device even if no media was detected. Fix will be backported shortly: https://bugzilla.redhat.com/show_bug.cgi?id=583616 > So I tried to store the (preallocated raw) VM image on my external > driver, but that fails too.

We don't create one of the latter out of the box. - Cole _______________________________________________ virt mailing list [email protected] https://admin.fedoraproject.org/mailman/listinfo/virt
