[libvirt] vm tunable memory and cgroup

[yue]

hi,all
1.
is there any relationship between cgroup and tunable memory ? if i adjust vm's memory, if cgroup has any responding action?
<memory unit='KiB'>1048576</memory>
<currentMemory unit='KiB'>524288</currentMemory>
2. it seems that  the memory.limit_in_bytes of a vm in cgroup is twice over vm's assigned memory?
addtional, blkio.sectors  does not equal  sectors calculated from inner vm.
how limit_in_bytes, sectors   are calculative?              what is the relationship between them? 
 
thanks
