Re: [libvirt] [PATCH] Add support for -enable-kqemu flag

Previously QEMU enabled KQEMU by default and had -no-kqemu. 0.11.x switched to requiring -enable-kqemu. 0.12.x dropped kqemu entirely. This patch adds support for -enable-kqemu so 0.11.x works. It replaces a huge set of if() with a switch() to make the code a bit more readable. This patch was inspired by the one John Lumby send to the list a while ago, but the way I've implemented it is more in line with the logic we have for KVM.
