Yes, Marc-Andre Lureau, nothing after. The Xorg.0.log content is before black screen i caught from guest. reverting patch from 1076728 in rhel6 also solves issue there sent patches to fix rhel7 guest: http://lists.freedesktop.org/archives/spice-devel/2014-August/017182.html http://lists.freedesktop.org/archives/spice-devel/2014-August/017183.html rhel6 is fixed with xorg-x11-drv-qxl-0.1.1-1{1,3}.el6 (12 should never be released) *** Bug 1152593 has been marked as a duplicate of this bug. *** for qa: this bug was easily reproducible at the time of the fixes were provided, you just need to resize in very very large size (bigger than framebuffer) and you reach various issues solves here, kernel/qxl should NOT over allocate framebuffer or it will reach "qemu guest bug" and bad thing happen (black screen usually)! Unfortunately, it is something that #1076728 allows to do in rhel6 too.. so the patches for kernel are tracked in #1158233, and here is a fix for xorg qxl/kms to fallback to previous working configuration. In short, #1076728 is wrong and must be reverted asap, #1158233 is required to avoid reaching qemu "guest bug", and this bug is for xorg qxl/kms driver. Created attachment 970383 [details]
