-------------------------------------
Adding more information from the email thread(probably missed here):
{quote}Hi Milan, sorry for missing this.
In short, it looks like a libvirt/qemu error, I guess it lays
somewhere in the nested environment the Jenkins slave runs at. I was
able to extract the libvirt log from this specific run, but there is
nothing useful there, except that there was no proper termination.
From reading here[1] it might be related to a load on the hypervisor,
and the timeout configured for libvirt to wait for qemu. Unfortunately
looking at the this[2] thread, it seems that a patch to configure the
timeout never got into libvirt, which leaves us with a default of 30
seconds, and that might not be enough in our nested environment. I
presume that if the hypervisor which the Jenkins slave runs is highly
loaded, then when we try to start the vdsm_functional_tests_lago VM,
it might take more than 30 seconds for qemu to respond.
Another indication of this "hypothesis" is that I never seen this
error on OST - which uses bare-metal slaves.
Evgheni, do we have the load monitoring on the hypervisor that runs
vm0065.workers-phx.ovirt.org? Not sure if we added that eventually.
