Re: [libvirt] 'dommemstat' is not working for LXC hypervisor.
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?
Regards,
Srikanth.

Hi Daniel,
I am using libvirt version 0.8.0. I created a domain 'srikanth_vm'
using 'lxc' hypervisor. I am able to start the Domain. But, I am not
able to get the memory stats for that Domain.
If I issue 'dommemstat Srikanth_vm' in the virsh console, the
following error is throwing:
error: Failed to get memory statistics for domain srikanth_vm
error: this function is not supported by the hypervisor:
virDomainMemoryStats
That is expected - no one has implemented the dommemstat API for the LXC
driver yet, though it should be really quiet easy todo so. All the info
should be available already via the memory cgroup controller
Can you please let me know, how can I get memory stats for a
particular domain in libvirt?
The virDomainGetInfo API / virhs dominfo command shows you the overall
allocated memory. The dommemstats command gives you a finer breakdown of
usage of that memory by the guest
