Screencast showing the issue

See the attachment. Using spice resize-guest in F22 virt-manager, with F22 Beta workstation in the VM.

Resizing the window up, the VM will change resolution accurately. But shrinking the window doesn't generate any change in the VM. 100% reproducible for me (sorry the video doesn't show more, gnome-shell screencast crapped out)

Same setup works fine with a rhel6 guest, so I don't think it's a virt-manager issue
Comment 1 Marc-Andre Lureau 2015-04-15 21:13:13 UTC 
Can you check xrandr has the correct + preferred and * current during resize? If yes, it's a gnome/shell regression, if not it's a qxl drm driver regression.
Comment 2 Cole Robinson 2015-04-15 21:40:01 UTC 
Sorry not entirely sure what I'm looking for. Here's the raw output.

drm driver regression, sticky prefered resolution, gnome-shell takes the largest

Did you resend this with the signed-off-by and stable CC'd?
Comment 6 Jonathon Jongsma 2015-08-20 19:07:18 UTC 
Hi Josh,

I was unfamiliar with what Dave meant by "cc stable", so I was waiting for his answer before re-sending. But I found some kernel docs suggesting to add a CC: tag to the git commit. So I've just re-sent my patch with that included. Hopefully I did it correctly. (the email may be stuck in the moderation queue, though...)
Comment 7 fulminemizzega 2015-08-26 22:41:03 UTC 
Hi,

I tried the fix you posted on f22 and it works, when will it be accepted? Will it be in linux-4.3 or f23?
Thanks,
fmiz
Comment 8 Josh Boyer 2015-08-27 14:57:44 UTC 
I've applied v2 of the patch to all branches in Fedora.  This will be in the rc8-git2 builds in f23/rawhide and in whatever build we do next on f21/f22.
Comment 9 fulminemizzega 2015-08-27 21:36:01 UTC 
Hi,

I did some other testing, and tried the same patched kernel on xfce and lxde f22 spins, but it did not solve the issue. I don't have tried rawhide.
I also found this, from February: https://ask.fedoraproject.org/en/question/63490/fedora-21-lxdexfcekde-guests-with-qxlspice-dont-auto-resize/

I don't know if this "helps", but I also tried debian 8.1 stable + xfce 4.12 (from testing), and resizing works. Debian stable is on linux 3.16.
I used virt-install to create both guests, used --os-variant=fedora22 for Fedora and --os-variant=debian7 for debian, the main difference I noticed is that the debian xml definition does not have a qemu-ga channel device.
