Description of problem: When starting a VM, Xen dies with "ERROR (XendBootloader:43) Disk isn't accessible" when using a block-backed disk and SELinux enforced Version-Release number of selected component (if applicable): F16 Beta How reproducible: Unknown. I'm going to try doing a fresh install of a VM tomorrow, see if that fixes it. Steps to Reproduce: 1. Ensure SElinux is in enforcing mode 2. Start a VM (using xm create config.file or similar) 3. Watch it die Actual results: xm create prints an error ("Error: Disk isn't accessible") and dies Expected results: Xen VM comes up as per normal. Additional info: avc denial in dmesg: [ 887.378877] type=1400 audit(1319126448.379:25): avc: denied { read } for pid=3168 comm="xend" name="dm-6" dev=devtmpfs ino=13634 scontext=system_u:system_r:xend_t:s0 tcontext=system_u:object_r:fixed_disk_device_t:s0 tclass=blk_file This VM was created with virt-install under F15, so SELinux labels should have been set correctly. Also, http://fedoraproject.org/wiki/FedoraXenQuickstartFC6#SELinux (FC6 is ancient, I know) says "Block device backed disks are already labelled correctly to allow them to pass SELinux checks." which no longer seems to be the case.
