I had a similar problem some weeks ago. Finally I found out that my VM
running WinXP was working on a non-acpi system (maybe I started kvm
with -no-acpi option during the installation). In the Device Manager
there has to be the entry Computer->"ACPI Multiprocessor PC".

Hi Jason,
We already have patches that implement similar functionality here in

They're not yet committed upstream because they're still quite fresh.

The in-kernel speaker emulation is only a dummy and also unneeded from
the performance point of view. Rather, it takes user space support to
generate sound output on the host, e.g. console beeps.
To allow this, introduce KVM_CREATE_PIT2 which controls in-kernel
speaker port emulation via a flag pa
When using the in-kernel PIT the speaker emulation has to synchronize
the PIT state with KVM. Enhance the existing speaker sound device and
allow it to take over port 0x61 by using KVM_CREATE_PIT2 where
available. This unbreaks -soundhw pcspk in KVM mode.

I thought that one use case of VT-d2 interrupt remapping was to be able to

In both interrupt remapping and no interrupt remapping cases, interrupts from
the passthrough device are still delivered to the host kernel. KVM then
injects the interrupt to guest via vlapic->vioapic->vmcs path.

Does KVM allow passing through a full multi-function PCI device to a guest, and
make that device appear as a whole multi-function device rather than as
