I wound up manually changing the network configs on my hosts during other updates, one at a time. Then I migrated off the lower MTU host and repeated. Seemed to be minor extra bit of pause after migration completed, then things were fine (and I manually updated MTU settings on the VMs at that ti

3.5.1. It’s really a “clean and tidy” thing now that I’ve got the network cleaned up, so not urgent but nice to have. Thanks for the info! > On Jan 28, 2015, at 4:05 AM, Dan Kenigsberg wrote: > > On Wed, Jan 28, 2015 at 11:03:14AM +0200, Lior Vernia wrote: >> Hi Darrell! >> >> There's currentl

Hi Darrell! There's currently no clean way to do this - we'll be looking to fix this in 3.6 (https://bugzilla.redhat.com/show_bug.cgi?id=1055454). You haven't mentioned which version of oVirt you're running - if it's 3.4 or lower, I think it would suffice to change ifcfg files on your hypervisors

I finally got a couple of networks our from behind a wan based layer 2 bridge that required me to run at MTU 1448, and would like to get back up to MTU 1500. I see the GUI won’t let me do that while the network is in use. Any way around this, clean or otherwise? Restarting VMs to update them is
