Public bug reported: [Impact]
virsh command is hang if there is broken VM on broken NFS This is affected to Xenial [Test Case] 1. deploy VM with NFS storage ( running ) 2. block NFS via iptables - iptables -A OUTPUT -d NFS_SERVER_IP -p tcp --dport 2049 -j DROP ( on host machine ) 3. virsh blkdeviotune generic hda => hang 4. virsh domstats => hang 5. virsh list => lang [Regression] After patch, we can command domstats and list with short timeout. and libvirt-bin needs to be restarted. so if there are many VMs it will be affected short time while it is restarting.
