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.
Given what little information you've provided, it's very difficult to do anything other than speculate about the cause of your problem, but perhaps you're hitting: https://bugzilla.redhat.com/show_bug.cgi?id=689030 Dave
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

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
