Description of problem: I have a 16:9 screen, but my (kvm) guests aspect ratio is 4:3. When I use "scale display", I get a deformed scaled-screen of my guests. Version-Release number of selected component (if applicable): I've tried only 0.7.0. Expected results: I see two possible resolution for this bug: 1) make guests run with the same aspect ratio of the host; or 2) make "scale display" maintains the aspect ratio of guests.
Thanks for the report Does this still happen in 0.8.0? Maybe you could attach a screenshot to show how bad it looks?
FWIW, virt-viewer 0.2.0 has completely re-written from scratch scaling / auto-resizing behaviour, which will always show guest at 1:1 where space exists on host, and if it needs to scale down/up to fit, it will always maintain aspect ratio unless explicitly overridden by the user. We should probably make virt-manager implement the exact same logic. The original logic for scaling vs scrolling & auto-resizing was pretty crude by comparison.
Created attachment 357351 [details] my guest at fullscreen w/o scale Here is my 4:3 guest running in a 16:9 host. Note the two thin black bands at the top (just under virt-manager menu) and at the bottom.
Created attachment 357352 [details] my guest at fullscreen w/ scale Here is my 4:3 guest running in a 16:9 host. Now the two thin black bands are no more, but aspect ratio of the guest is not preserved.
I've taken those screenshots with virt-manager 0.8.0, so problems still remains.
Addressed upstream now. Moving to POST, we will be cutting a new release soon.
This should be fixed in virt-manager-0.8.1-1.fc13 which will be in the next rawhide compose.
