Public bug reported:
As has been reported multiple times (*), there were a regression in
qemu-kvm from 0.11 to 0.12, which causes significant slowdown in cirrus
vga emulation. For windows guests, where "standard VGA" driver works
reasonable well, -vga std is a good workaround. But for e.g. linux
guests, where vesa driver is painfully slow by its own, that's not a
solution.
