@Former user el7/fc24 label can be removed as they are used by various jobs that can all run in VMs.

All x86_64 VM slaves now have the "Use this slave as much as possible" policy set. ppc64le VMs and bare metals on the other hand run just labeled jobs.

On the other side - we've got a bunch of el7 VM slaves all having the "Only build jobs with label expressions matching this node" so they are currently idle while they could be running check-patch jobs (after double-checking this job does not attach to a label). Will change this setting on VMs to get the queue processed faster.

I haven't changed the labels, only the setting to only build jobs with label expressions matching the slaves label.
@Former user should we just leave the 'integ-tests' label for those slaves?

Not sure what you changed, but I still see extra labels on bare metal slaves, for example:
http://jenkins.ovirt.org/computer/ovirt-srv20.phx.ovirt.org/

fc24 integ-tests phx physical

check-patch runs due to existance of "fc24" label on the node.

Other bare metals having extra labels:
