[libvirt] [RFC][PATCH 0/2] Fix zero cpu shares handling

Hello, This series tries to fix the behavior of <cputune><shares>0</shares></cputune> (means default shares of 1024) and virsh schedinfo --set cpu_shares=0 (means minimum of 2) If 0 was explicitly specified, treat it as a valid value (which will get converted to 2 by the kernel) Re-read the shares value to reflect the cpu shares in live XML. In v1, I've tried to change the schedinfo behavior instead, but I have not found a way to reset the value to the kernel default (which is currently 1024 - see ROOT_TASK_GROUP_LOAD in kernel/sched/sched.h in Linux source) other than writing it to the cgroup fs.
