Regression tests on ppa complete, I'm good to sponsor this once the security updated are complete.
Since those are complex that might be a few more days.
I'll keep an open todo on this to check the status.

virsh api is stuck when vm is down with NFS broken
Status in Ubuntu Cloud Archive:
Status in libvirt:
Status in libvirt package in Ubuntu:
Status in libvirt source package in Xenial:
virsh command is hang if there is broken VM on broken NFS
This is affected to Xenial, UCA-Mitaka
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
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.
This bug is fixed in redhat bug report and mailing list and git
and it is merged 1.3.5 upstream
