How reproducible:

Steps to Reproduce:

22:11:40.067: warning : qemudStartup:1150 : Unable to create cgroup for driver: No such device or address
22:11:40.301: warning : lxcStartup:1748 : Unable to create cgroup for driver: No such device or address

Additional info:
selinux in enforcing mode, no AVC denials. i'll be gone for a week without access to this machine, but after that i should be able to answer any questions you may have. sorry about the timing.

also, got this line in /var/log/messages: Jul 26 21:48:25 localhost libvirtd: Could not find keytab file: /etc/libvirt/krb5.tab: No such file or directory

Comment 1 Luc de Louw 2010-09-28 08:09:27 UTC

Add the following to /etc/fstab and libvirtd works again:

cgroup /cgroup cgroup  cpuset,cpu,cpuacct,memory,devices,freezer,net_cls

Comment 2 Stefan Berger 2011-02-04 15:41:25 UTC

I had a similar problem. The reason on my machine was a corrupted qemu binary (some linklib was missing) that libvirt was trying to probe while starting. I believe I found it with 

export LIBVIRT_DEBUG=1

skipping over the iptables errors that libvirt tolerates to fail.

Comment 3 Conrad Meyer 2011-02-04 16:47:28 UTC

libvirtd has gone back to working for me since I filed this (without any action on my part other than installing updates). go figure.
