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.
