It happens even if you start a VM directly with qemu from the command line with the qxl driver (option -vga qxl) independently of virt-manager.
For example, the following command will hang on boot:
/usr/bin/qemu-system-x86_64 -m 2G -smp 2 -localtime -no-reboot -cpu core2duo -enable-kvm -drive file=/tmp/disk.img,if=ide,media=disk -boot menu=on -soundhw all -display sdl -vga qxl -monitor stdio -cdrom /home/j-lallement/iso/ubuntu/artful-desktop-amd64.iso
