Title:
Windows 7 guests hang on bootup when qxl video is used
Status in QEMU:
New
Status in qemu package in Ubuntu:
Fix Released
Bug description:
I installed libvirt-bin and virt-manager on Ubuntu 16.04. I created a
new VM for Windows 7, basically with default settings, which includes
qxl video.. The Windows boot process hangs with the "Starting
Windows" animation. CPU and disk I/O drop to zero, and it continues
animating.... forever and ever... It never finishes booting. But it
doesn't fully "hang" either: the animation continues to animate.
As a workaround, I set the video mode to "Cirrus" and then Windows
boots but it is slow and limited. And also apparently to be avoided:

harmful/
I can confirm it's only when qxl is enabled, because if I switch from
Cirrus back to qxl, it hangs again - and going back to Cirrus again
"fixes" the problem.
