It's better to put your system info here, like CPU. Besides, you may use "selinuxenabled ; echo $?" to check if selinux is enabled. Status 0 means selinux is enabled, otherwise not. Hi, I have exact the same error after an update yesterday. Before this update F12Beta - released yesterday! :-) - was running fine. 1. My smolt profile can be found here [1] 2. I'm running selinux in permissive mode, so I get AVC-messages. Actually I get tree messages, see [2] [1] http://www.smolts.org/client/show/pub_18cdf89a-040b-44e0-9859-907a28d290f7 [2] BZ: #530189, #530191, and #530192 Hope this info helps. Martin Kho [SOLVED] Hi, Danial Walsh has responded on bug report: #530192: He said: "This is a leaked file descriptor from qemu which should be changed. But the error is caused by a bad entry in your /etc/fstab, that was introduced in F11. Your /etc/fstab devpts line should look like grep devpts /etc/fstab devpts /dev/pts devpts gid=5,mode=620 0 0 Otherwise svirt through glibc will attempt to fix the labeling of the pty. Fixing this and executing mount -a should fix the problem." This also fixed the original issue. Martin Kho Thanks for the hints Martin Gianluca, could you check your devpts entry in /etc/fstab? Mark, I confirm Martin's hint fixed my issue related to devpts. Many thanks to both of you! ;-) Ciao, Gianluca Thanks Gianluca *** This bug has been marked as a duplicate of bug 515521 *** |
