This works for me on Qemu 4.1.0 (and current git head). It has worked 
unmodified since prior to v2.9.

qemu -enable-kvm \
 -m 8192\
 -rtc base=localtime\
 -vga qxl\
 -device qxl\
 -net nic,model=virtio\
 -net tap,ifname=tap0,script=/etc/qemu-ifup,vhost=on\
 -usbdevice tablet\
 -spice port=5930,disable-ticketing\
 -device virtio-serial\
 -chardev spicevmc,id=vdagent,name=vdagent\
 -device virtserialport,chardev=vdagent,name=com.redhat.spice.0\
 -smp 3,maxcpus=3,cores=3,threads=1,sockets=1\
 -cpu qemu64,hv_relaxed,hv_spinlocks=0x1fff,hv_vapic,hv_time \
 -drive 
file=/server/VM/Cadbox.raw,if=virtio,aio=threads,format=raw,cache=unsafe 
-boot c \
 -drive 
file=/server/VM/Cadbox_swap.raw,if=virtio,aio=threads,format=raw,cache=unsafe 
\

This gives me a Windows 7 guest with dual-head.

Brad
