Problem :
On MacOSX Ethernet connection has problems when KVM used.

MacOSX guest cannot communicate without -kvm-irqchip option.

Os recognizes Ethernet card properly but cannot communicate with host, cannot
get IP (like 10.0.2.15 from qemu), etc.

The command I use to launch the vm is:
qemu-kvm -hda ./MacOSX.vdi

The problem also appearing with -no-kvm-pit.
The problem stops appearing with -no-kvm-irqchip and -no-kvm.

Software:
Host:OpenSUSE 11.3 with Vanilla 2.6.38-rc3/AMD64, 
Guest: MacOSX 10.6.0
KVM: QEMU emulator version 0.14.50 (kvm-0.14.0.rc0-69.1) (From OpenSUSE repos)

Hardware configuration:
AMD Phenom II x4 2.6 Ghz.
Biostar 790GX A2+
4GB DDR2 PC800 RAM
