[libvirt] [PATCH 0/6] Add BlkIO and CPU/mem stat API implementations for lxc

This patch set adds block io, memory and domain cpu statistics API slot implementations to the LXC driver, in order to get linux container monitoring and accounting a bit closer to qemu standards. The last patch is a tad quirky (happy to hear suggestions on alternative ways), in that it widens the permissible value set at the .domainBlockStats slot: for lxc guests, it is relatively likely to have zero disk devices, since host filesystems can be used via passthrough bind mounts. Therefore, passing the null ptr or the zero-length string as device path, is interpreted as 'return summary stats for the entire domains's block io'. Thorsten Behrens (6): Add util virCgroupGetBlkioIo*Serviced methods. Implement domainMemoryStats API slot for LXC driver. Make qemuGetDomainTotalCPUStats a virCgroup function. Implement domainGetCPUStats for lxc driver.
