update: its not only happening with smp guest, but with non-smp guest.
mcelog is empty. the commandline for a debian lenny im using is:

/usr/src/kvm-84/qemu/x86_64-softmmu/qemu-system-x86_64 -S -M pc -m 512
-smp 1 -name vm03 -uuid 0b5e3a60-9111-0289-84b5-98cdf27450ac -monitor
pty -boot c -drive
file=/kvm/domains/linux-test/image.img,if=ide,index=0,boot=on -drive
file=,if=ide,media=cdrom,index=2 -net
nic,macaddr=54:52:00:0b:a1:26,vlan=0 -net
tap,fd=12,script=,vlan=0,ifname=vnet0 -serial none -parallel none -usb
-vnc 127.0.0.1:0

(i know the path looks weird but its ok, i didnt want to do a make
install, the right modules are also loaded)

if i add -no-kvm the host just seem to run fine..
