PHX updates - hypervisors in Jenkins datacenter

Hi all, As part of the upgrade process to 3.6 I will be rebuilding all hypervisors to CentOS7, and I'm starting with the Jenkins Datacenter. For this, I am evacuating slave VMs by shutting them down and restarting in the new cluster with CentOS hosts. I'm currently working on ovirt-srv04 so please don't schedule any VMs on that host until it's rebuilt. I found several VMs running on that host which are not listed on Jenkins so I can't mark them offline there for the update period: fc21-vm01.phx.ovirt.org el6-vm06.phx.ovirt.org If anyone knows what these VMs are used for - please tell me, otherwise I will just restart them as well. Also this VM is present on this hypervisor: artifactory.phx.ovirt.org Is it used by the slaves? Can it be shut down for a few minutes? I'm not sure I will be able to live migrate it even as the F20 hosts we have in the old cluster have issues with live migration even to other F20 hosts. Regards, Evgheni Dereveanchin
