[libvirt] [PATCH 0/8] Support cgroups in QEMU driver (v2)

[Daniel P. Berrange]

This is an updated series of the v1 patches here:

http://www.redhat.com/archives/libvir-list/2009-July/msg00435.html

I have re-ordered the patches a little to put the generic refactoring
all first. I identified some bugs in the existing LXC driver schedular
parameter handling which I fixed. Also fixed virsh to use the correct
data types when setting schedular parameters instead of hardcoding
a bogus type. Finally, I've made QEMU's use of cgroups configurable.

Daniel P. Berrange (8):
  Use enums for cgroup controller types / labels
  Use virFileReadAll/virFileWriteStr for key cgroup read/write helpers
  Make cgroups a little more efficient
  Refactor cgroups to allow a group per driver to be managed directly
  Place every QEMU guest in a private cgroup
  Implement schedular tunables API using cgroups
  Use cgroups for block device whitelisting in QEMU guests
  Make QEMU cgroups use configurable
