Daniel, My requirement is to get how much memory is free in the guest domain. Can you please let me know, how can I do that?
Do you enable cgroup memory subsystem? If so, something wrong in lxc driver of 0.8.0. BTW, 'Used memory' includes both RSS and caches, so if you need total-RSS value, you should use dommemstat.
And also, as you said it's quite easy to implement dommemstats for lxc driver, is there any possibility to implement that?
We can get statistics of dommemstat easily through memory.stat of cgroup.memory subsystem except statistics of page faults. ozaki-r

Thanks for the reply Daniel. Virsh dominfo dommand showing following results:
Id: 32473 Name: vm1 UUID: f13bc513-15f2-1dd1-74f6-18c47931ece9 OS Type: exe State: running CPU(s): 1 Max memory: 5000000 kB Used memory: 5000000 kB Autostart: disable
Though whatever services running on the domain, every time used memory
is showing as 5000000 kB. Is that result is correct?
The 'Max memory' 5000000 KB is the hard limit that is allocated to the container. I thought that the 'used memory' field would be lower, but its possible we don't have the actual stats for used memory so just set both the same. I'd have to research the code again to answer for sure...
