[ovirt-users] SPICE and Windows 10

[Colin Coe]

Hi all

We've just updated our dev environment from 4.1 to RHV 4.3 and found that
while a lot better, Windows 10 under SPICE still isn't great.

We're running dual screen VMs at 2560x1440 resolution.  The Windows login
screen is particularly bad although once logged in it gets better but not
great.  The benchmark here is Windows 10 vs Windows 7 VMs.

We've gone into settings / advanced and set "configure for best
performance".  Latest RHV tools (4.3-6) are installed.  We've also created
"/etc/ovirt-engine/osinfo.conf.d/20-overload.properties" containing:
os.windows_10.devices.display.vramMultiplier.value = 4
os.windows_10x64.devices.display.vramMultiplier.value = 4

When we set the multiplier to 8, as recommended in another thread,
ovirt-engine fails to restart.

I know there have been a few threads on this but I'd like to ask what is
the advice for RHV/oVirt 4.3 to make Windows 10 faster?  VDI on RHV makes
up an important part of what we do and RDP, VNC, etc are not an option.

Thanks

There is no Windows 8+ QXL driver, so things are working in some VGA
fallback mode.
