can not start "-vga std" after upgrade to git snapshot

[John Wong <johnw@wonghome.net>]

After upgrade to snapshot
"http://git.kernel.org/?p=virt/kvm/qemu-kvm.git;a=snapshot;h=db311e8619d310bd7729637b702581d3d8565049;sf=tgz",
i can not see the "-vga std" screen, kvm will start the vnc instead vga.

my kvm command like this:

${KVM} -drive
if=virtio,media=disk,cache=none,format=qcow2,file=${IMG},boot=on \
-drive if=ide,media=disk,cache=none,format=qcow2,file=${NTFSDISK} \
-net nic,vlan=${NUM},model=virtio,macaddr=00:AA:BB:CC:DD:0${NUM} \
-net
tap,vlan=${NUM},ifname="${iface}",script=/etc/kvm/kvm-ifup,downscript=/etc/kvm/kvm-ifdown
\
-localtime -smp 2 \
-usb -usbdevice tablet \
-soundhw all \
-k en-us -monitor stdio \
-mem-path /hugepages \
-enable-kvm \
-m 2048 -vga std -boot order=c,menu=off


please help, and thank you.
