[libvirt-users] API for retrieving resource metrics from VMs?

[BYEONG-GI KIM]

Thank you indeed!

That information would be really great help for me. I'll look for the
libguestfs. By the way, you mentioned that the tool would be better not to
use frequently, so... Does the tool have any performance issue?

Best regards
