Comment 30 for bug 1571209

Slowed down further (lmited to 2 cpus), startup of the guests takes minutes now.
Still no issue to be seen.
The socket is around and working, while in background the guests start slowly but surely.

The test is now:
# cat test-restart.sh
#!/bin/bash
set -uxe
#starts off
date
ls -laF /var/run/libvirt/libvirt-sock
sudo service libvirt-bin status
date
# start service
sudo service libvirt-bin start
date
# check if socket is available immediately
ls -laF /var/run/libvirt/libvirt-sock
sudo service libvirt-bin status
ls -laF /var/run/libvirt/libvirt-sock
# this might take a while as the dameon queues requests
virsh list
date

With 100 Guests shut down, but set to autostart on a 2 cpu system.
That takes about 5 minutes to start the guests, but the service is up and ready on the socket before doing all that.
Did you face something else?

@Ed / @Guessi
I know it is a long time, but I'd need to get something reproducible to go on fixing this for artful. If you can help me with examples that do please let me know.

@Guessi:
I tried with the degraded RAID but it worked for me as well, maybe it is just not the most reliable repro.

@Ed:
the original case lacks some details what actually failed e.g. what dependent services and how it was triggered in your case.

Keeping incomplete status on Trusty for now :-/
