Hi

Is it possible/supported to upgrade from Ovirt 3.6 straight to Ovirt 4.2 ?

No, you go through 4.0, 4.1.

Does live migration still function between the older vdsm nodes and vdsm nodes with software built against Ovirt 4.2 ?

Yes, keep the cluster level at 3.6.

We changed a couple of the vdsm python files to enable iscsi multipath on direct luns.
(It's a fairly simple change to a couple of the python files).

Nice!

Can you please contribute those patches to oVirt?

We've been running it this way since 2012 (Ovirt 3.2).

Many Thanks

Gary Lloyd
