Hi,
I've got a small problem using libvirt-1.0.5.1 (with the latest patch in the v1.0.5-maint branch on git added). I'm using slackware64-14.0 but the situation is exactly the same described on a debian bug
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=707201
When trying to start a domain I got
error: Failed to start domain debian-wheezy-xfce error: Unable to initialize /machine cgroup: Invalid argument
with this in libvirtd.log
virCgroupDetect:373 : Failed to detect mounts for /machine qemuInitCgroup:425 : Unable to initialize /machine cgroup: Invalid argument
and the error goes away if I unmount /sys/fs/cgroup.
Reverting to 1.0.4 fixes this,
sorry, just to report the same effect with 1.0.6: this is my /sys/fs/cgroup layout
and this is the corresponding stuff in /var/lib/libvirt/libvirtd.log (with log level 1) when I issue a
# virsh start s64cont
as I've had a look at
http://libvirt.org/cgroups.html
I'm just wondering if systemd is necessary (we don't have it in Slackware) or I'm simply missing something...
No, systemd is definitely /not/ mandatory. Can you provide your /proc/mounts file contents Libvirt seems to be failing to detect the mount points 2013-06-06 15:49:37.688+0000: 29305: debug : virCgroupNewPartition:1248 : path=/machine create=1 controllers=5f 2013-06-06 15:49:37.688+0000: 29305: debug : virCgroupNew:808 : parent=(nil) path=/machine controllers=95 2013-06-06 15:49:37.688+0000: 29305: debug : virCgroupDetect:359 : group=0x7f601007f6e0 controllers=95 path=/machine parent=(nil) 2013-06-06 15:49:37.688+0000: 29305: error : virCgroupDetect:366 : Failed to detect mounts for /machine 2013-06-06 15:49:37.688+0000: 29305: error : qemuInitCgroup:733 : Unable to initialize /machine cgroup: Invalid argument also do you have anything in /etc/libvirt/qemu.conf set for the cgroups controllers setting ?
