This is my full command line, where $qemudir is my qemu git directory.

$qemudir/i386-softmmu/qemu -L $qemudir/pc-bios \
  -drive file=/tmp/test.img,cache=off,if=ide \
  -m 500 -no-reboot \
  -kernel /tmp/libguestfsivUi3g/kernel -initrd /tmp/libguestfsivUi3g/initrd \
  -append 'panic=1 console=ttyS0 udevtimeout=300 noapic acpi=off 
guestfs=10.0.2.4:6666 guestfs_verbose=1' \
  -nographic -serial stdio \
  -net channel,6666:unix:/tmp/libguestfsivUi3g/sock,server,nowait \
  -net user,vlan=0 \
  -net nic,model=virtio,vlan=0 \
  -no-hpet -rtc-td-hack

The above works with qemu 0.10.4, but not with qemu 0.10.5 where there
is a hang (which I'm investigating - first send from guest -> host
works, response from host -> guest disappears into the ether
somewhere).

Good to know, thanks.
