Description Andrei Stepanov 2015-10-19 15:40:00 UTC 
virt-viewer with --full-screen parameter on 4k monitor doesn't update resolution of guest VM

virt-viewer v2.0-48 (Windows 7 32)

client's native resolution is: 3840x2160
virt-viewer -f spice:\\xx.xx.xx.xx:3000 -f

It works as expected on the same client/monitor with resolution 1920x1080

Comment 8 Andrei Stepanov 2015-10-19 16:02:57 UTC 
Switching from window mode, using menu View->Full Screen also is broken.
Resolutions stays the same as it was for window mode.
Comment 9 Pavel Grunt 2015-10-20 06:17:58 UTC 
the client is virt-viewer v2.0-48 (Windows 7 32), changing product & component to rhevm
Comment 10 Pavel Grunt 2015-10-20 06:23:26 UTC 
How the VM was created?

Most likely it doesn't have enough memory for the 4k resolution. In that case the RHEL guest fallbacks to the previous used resolution.

Changing from

<model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='1'/>

to

<model type='qxl' ram='131072' vram='131072' vgamem='32768' heads='1'/>

-vga qxl -global qxl-vga.ram_size=134217728 -global qxl-vga.vram_size=134217728 -global qxl-vga.vgamem_mb=32

Allows to go in 4k full screen mode

Was it tested? What's the overall performance of a VM with more graphics memory? What's the graphics performance?
Can it be migrated, for example?
