Greetings, This is my first stab at this mailing list. Forgive me if I am over/under verbose. We have been running KVM for a while now and love it. Recently I have noticed a weird anomaly that is getting on my nerves. When I clone (GUI or virt-clone from CLI) both* virt-manager* and *virsh* enquiries get extremely sluggish. Using top I cannot see any resource issues. No I/O wait, the load average show noting outside of the normal, nothing taking CPU or Memory. I have notice that in a couple of the instances the libvirtd daemon was stopped. We have more than twenty (20 +) VM's running - they all seem fine. The metal server is a beast of an 820 with 192GB of RAM and 64 CPU's. The load average rarely creeps above 2 or 3. Do not think it is a resource issue. I can write a test file to the filesystem/volume where the images live at over 350MB/s. The sluggishness disappears after a reboot. If I clone a VM ... back again ... Any ideas? Thanks in advance, Tom Ainsworth RHCSA
