[libvirt] [PATCH 0/5] Refactoring of cgroups usage

[Daniel P. Berrange]

Currently libvirtd creates its basic cgroup hierarchy when it
starts up. This is bad because if people mount cgroups after
libvirtd it is running it doesn't detect this. The second
issue is that the driver code re-creates the virCgroupPtr
instance for a domain over & over again, which is inefficient
and bloats the code. Finally, if the driver is configured to
only use a couple of the cgroups controllers, we are still
creating the directories under all of them
