I tried installing XEN while running SElinux in enforcing mode, probably not a good idea but.... When I tried creating the first virtual machine (using virt-manager), I got an SELinux error flagged in setroubleshooter. I compounded my errors by applying the fix suggested in setroubshooter (basically relabelling the /lib directory if my memory serves). This generated about 70 more se errors before I could get to the ^C keys. Now on reboot I get the following error which pops me in to the fsck shell. /sbin/dmsetup error while loading shared libraries libdevmapper.so.1.0.2 If I apply the grub option selinux=0 the system boots just fine, but of course selinux is disabled. I tried disabling selinux from the GUI, reboot, re-enable reboot. I was hoping the re-label on re-enable would fix the issue, but the system does not boot far enough to get to the relabeling phase. Can anyone tell me how to fix the selinux setup so that it can be re-enabled? Thanks, Mal. Im running a fully updated FC6 on Core 2 Duo 6600/Asus P5W motherboard, which works great except for having nothing in /proc/acpi/thermal_zone.
