Before starting any guest, the QEMU driver needs to figure out what version of QEMU is in use & thus determine whether it supports particular command line flags. We currently do that just by calling /usr/bin/qemu, since all the various qemu-system-XXX binaries share the same syntax. The only problem is that qemu-kvm does not neccessarily match the version of qemu installed. So we detect QEMU version 0.8.2, but KVM is 0.9.0 based. The result is that we pass the wrong style VNC argument to KVM & it fails to start. The second problem is that even if you only ever want to run KVM guests, you still have to have KVM itself installed. This patch tweaks the feature/version detection so we do separate detection just for KVM. With this applied I can successfully start KVM guests if the QEMU version is different, or even if QEMU is not installed.
