DB> mkdir /dev/cgroups/libvirt/lxc/{NAME}
I have a small (and not-yet-working) patch that uses libcgroup[1] to
setup a cgroup per container. This provides the ability to enforce the
<memory> quantity on the group through memory.limit_in_bytes. I've also
got some stubs that I plan to use to provide access to cpu.shares
through the scheduling parameters interface.
DB> echo "a" > /dev/cgroups/libvirt/lxc/{NAME}/devices.deny
DB> echo "c 1:3 rwm" > /dev/cgroups/libvirt/lxc/{NAME}/devices.allow
DB> echo "c 1:5 rwm" > /dev/cgroups/libvirt/lxc/{NAME}/devices.allow
DB> echo "c 1:7 rwm" > /dev/cgroups/libvirt/lxc/{NAME}/devices.allow
DB> echo "c 5:1 rwm" > /dev/cgroups/libvirt/lxc/{NAME}/devices.allow
DB> echo "c 1:8 rwm" > /dev/cgroups/libvirt/lxc/{NAME}/devices.allow
DB> echo "c 1:9 rwm" > /dev/cgroups/libvirt/lxc/{NAME}/devices.allow
Adding this functionality to what I have should be rather trivial, I
think.
I'm still working with the libcgroup folks to get some kinks ironed out,
but I will post the patches when we get something that works against
some version of libcgroup.
