Prefered Host to start VM instead of Pinned Host
Hi Guys, Is it an idea to have an option, not the first boot option, to set a prefered host for a VM to start on ? If you remove this host that it also does not complain about a pinned VM as it should faillback on "any host in cluster" in that way ? It's nice for static VM's on hosts that might be started on other hosts when the prefered host is gone, dead or whatever. Cheers, Matt
You can define a default cluster for this use case.

I don't get what you mean here, if there are two host in this cluster without pinning it would chose whatever it wants. If I create a seperate cluster for each host, I cannot have VM's which coult be running on each. It's more an and/and/or issue 2016-08-25 5:17 GMT+02:00 Yaniv Dary <ydary@redhat.com>:

In the edit VM dialog, if you show advanced options, there is a 'host' sub tab on the left. If you select that, there is a 'start running on' option. You can select the specific hosts(s) radio button. That will enable the multi select box that allows you to select a list of hosts this VM can run on. I think that will do what you are trying to do?

Hi, Yes, I'm aware of that, the issue there is. If you want to remove a host you first need to edit all pinned hosts, a fall back to Any Host In Cluster would be nice when you remove the host. Maybe I should have asked my question different :) 2016-08-25 13:53 GMT+02:00 Alexander Wels <awels@redhat.com>:

Matt you can use 4.0 labels feature. It does not give a 'preffered' selection behaviour but it does abstract the selection of vm and host. So all you need is to label your VM, in say label 'Web Sever' and then label the hosts you want to run this VM with the same label.
