Correct location for bug report: KVM domain hangs after loading initrd with Xenomai kernel

I'm not sure if this bug is located in userspace or in the kernel.
Could you let me know where to file it?

Bug:
Attempting to boot a 32 bit Debian guest with a Xenomai kernel inside
KVM causes it to hang and spin (using 1 full CPU core) after loading
the initrd, as determined by serial console output. The only error
message is "KVM internal error. Suberror: 1"/"emulation failure".
Booting a regular Debian kernel succeeds, as does running the Xenomai
kernel with software emulation (-no-kvm).

Info:
CPU: Intel Core i7-2670QM
Emulator: qemu-kvm 0.14.1
Host kernel: 3.0.0-15 (Ubuntu build), x86_64
Guest OS: Debian Squeeze, kernel.org 2.6.37 kernel with Xenomai 2.6.0
(config attached)
Qemu command: kvm -M pc-0.14 -enable-kvm -m 1024 -drive
file=/var/lib/libvirt/images/eve.img,if=none,id=drive-ide0-0-0,format=raw
-device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0
-netdev tap,fd=21,id=hostnet0 -device
e1000,netdev=hostnet0,id=net0,mac=52:54:00:b5:f4:00,bus=pci.0,addr=0x3
-chardev stdio,id=charserial0 -device
isa-serial,chardev=charserial0,id=serial0 -usb -device
usb-tablet,id=input0 -vga cirrus
Effects of flags: Adding one or both of --no-kvm-irqchip or
--no-kvm-pit has no apparent effect. Adding --no-kvm appears to
correct the problem.

Trace will be attached to the final bug submission.

Thanks,
