Hi,

does qemu-kvm's bios intentionally refrain from reporting hpet support via acpi or is this a bug? It works nicely with upstream (tcg & kvm mode).

Hi Jan. HPET is not in qemu-kvm yet because there are some issues unique to qemu-kvm regarding disabling of the in-kernel PIT. I have patches ready to submit and should be able to do so next week (long story), so hopefully this will be resolved shortly.
