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, but this exposes another thing that I report
even if I'm not sure it's an error: if I create a domain with 1.0.5.1 (I
use the latest virt-manager to do this), in the xml of the domain there's a
line that doesn't seem to have the close tag
<controller type='pci' index='0' model='pci-root'/>
If I revert to 1.0.4 the domain with this line in the xml doesn't even get
listed between the available domains and I got this in libvirtd.log
virDomainControllerDefParseXML:4838 : internal error Unknown controller
type 'pci'
deleting the interested line make it available again.
Please let me know if you need further informations on the matters.
