Testing MoM

[Doron Fediuck]

Hi Guys,
since mom is now required by vdsm, we'd like to have Jenkins running a few tests
of vdsm+mom to make sure we have no regressions, etc.

The thing with mom is, that we need a real host to see memory sharing (KSM)
kicks in correctly, and if the host starts swapping mom tunes the VMs memory balloon
to fix it.

So basically the question is, if we have a real jenkins slave, which we can use
as a hypervisor for mom tests. Obviously as a slave it may run other tests while
vdsm+mom tests are not running.

I thought about nested kvm, but IIUC advanced features such as memory balloon
may have issues there.

Appreciate your feedback on this.
