| QEMU PC emulator version 0.11.1 (qemu-kvm-0.11.1), Copyright (c) 2003-2008 Fabrice Bellard
from the debian package qemu-kvm (0.11.1+dfsg-1~bpo50+1)

/usr/bin/kvm -S -M pc-0.11 -enable-kvm -m 512 -smp 1 -name zoe -uuid 1885e784-c831-4ef8-9576-8eaa9abf3a8b -monitor unix:/var/lib/libvirt/qemu/zoe.monitor,server,nowait -boot c -drive file=/dev/vg_sookie_system/zoe-boot,if=ide,bus=0,unit=0,boot=on -drive file=/dev/vg_sookie_system/zoe-root,if=virtio -drive file=/dev/vg_sookie_system/zoe-swap,if=virtio -net nic,macaddr=00:16:36:40:00:0b,vlan=0,model=virtio,name=net0 -net tap,fd=25,vlan=0,name=hostnet0 -net nic,macaddr=00:16:36:40:05:0b,vlan=1,model=virtio,name=net1 -net tap,fd=28,vlan=1,name=hostnet1 -serial none -parallel none -usb -vnc 127.0.0.1:10 -vga cirrus -balloon virtio

And I had added "-cpu qemu64,-kvmclock" to that at either the front or the end.

Cheers,
