Public bug reported: 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: https://www.kraxel.org/blog/2014/10/qemu-using-cirrus-considered- 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.
