Re: [libvirt] virsh sechedinfo/memtune with libvirt-0.8.8
Hi
The bugzilla advice/patch below is not relevant here . Please see what
is the reason for virsh schedinfo / memtune not woking with libvirt-0.8.8
and libcgroup-0.36 while it does work with libvirt-0.8.3 and same
libcgroup .
Please dispatch to the appropriate person if you know the guy in charge.
thanks

Sorry . I have'nt got an answer from the user's list .
I have fedora14 installed with its standard libvirt-0.8.3. I can start
VM
using .xml files and also run: virsh schedinfo. the cgroup CPU
controller is mounted and active . In fact I have the path to the
Virtual
machine : /dev/cgroup/cpu/libvirt/qemu/<vm name>
I now upgraded to libvirt-0.8.8 from a tar ball ( configure , make ,
make
install) . I rebooted , new libvirtd started . virsh is working ok
(I can create a vm) except for the commands : schedinfo and memtune
that
e.g.
say upon ' virsh schedinfo<vm name>'
Scheduler : Unknown
error: Requested operation is not valid: cgroup CPU controller is not
mounted
But the CPU controller is mounted because I have the path :
/dev/cgroup/cpu/libvirt/qemu/ .
What I am missing is the<vm_name> group which is not generated despite
that the VM was generated ok by virsh create and I can access it.
Any idea what is missing ?
AFAIK, it's some problem of libcgroup:

Guess following will work for you:
# cgclear
# cgconfigparser -l /etc/cgconfig.conf
