According to QEMU/KVM graphics developers, when all things are considered (driver support in guest OSes, performance, features, etc.), VGA is clearly preferable fallback choice over Cirrus when using VNC on x86*. So it should be considered switching the default choice in oVirt.
Please note the switch shouldn't be done before SPICE QE tests it and confirms the change is OK.
introduce in new cluster level
convert on cluster upgrade with a warning
need to keep supporting 3.6-level clusters(and VMs) with cirrus, also on import
David & David - thoughts?
the current patch changes VNC to QXL, but there are issues with QXL on older guests. We need to either change that to VGA or revert back to CIRRUS
or keep CIRRUS as an option for people who have issues. I would still prefer to change the default away from CIRRUS to nudge users into more modern card
I tried to verify this RFE on version: 184.108.40.206-0.1.el7ev
The import flow work, but the CL upgrade is not working - means after CL upgrade the VNC/Cirrus do not switch to VNC/VGA.
Target release should be placed once a package build is known to fix a issue. Since this bug is not modified, the target version has been reset. Please use target milestone to plan a fix for a oVirt release.
hm, there was some discussion about changing existing VMs. Apparently it is not done right now, but we may still want to do that.
Changing to 4.0 CL is a good time to do that
Not included in 4.0.4 rc1, please don't move to QE until next build
I've been ignored. Moving back to modified.
Verified on version : 220.127.116.11-0.1.el7ev
Now the CL upgrade works properly.
