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
