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 ?
