Passing accel=kvm:tcg causes it to try KVM first if available with a fallback to TCG (emulated/JIT mode) if it is not available. With this the boot logs gain: +Hypervisor detected: KVM and also -Booting paravirtualized kernel on bare hardware +Booting paravirtualized kernel on KVM Among various other noise. If I rename my host /dev/kvm then this is reversed, although with the following message: Could not access KVM kernel module: No such file or directory failed to initialize KVM: No such file or directory Back to tcg accelerator. Q35 is a more modern emulated platform based on the ICH9 host chipset rather than the default "pc" I440FX (Pentium Pro / Pentium II era) emulation. See http://wiki.qemu-project.org/Features/Q35 for more info. Switching to Q35 is not a requirement for enabling KVM but seemed like a reasonable change.
