Every actions with VMs (attach disk, poweroff, resume, migrate & etc) takes from 30 to 60 seconds.
Host is not loaded.
Sometimes Sunstone stopes and process migrate to another host without errors.
Logs are clean. Maybe it is the problem with libvirt? But there are no problems with VMs and libvirtd log same clean.
How i can find problem?
