Re: [libvirt] 'dommemstat' is not working for LXC hypervisor.



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?
And also, as you said it's quite easy to implement dommemstats for lxc
driver, is there any possibility to implement that?

Regards,
Srikanth.

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...
