This patch (2914caa088e3fbbd) breaks autotest when a guest reboots after install; instead of rebooting, the guest is stuck in the bootloader or kernel. This was discovered in qemu-kvm, but applies to plain qemu too. The commit above is broken, it's parent is good. -- error compiling committee.c: too many arguments to function
