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.

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...
