  I can't get X to work on the guest.  Text console is OK, but no X.  I
ticked support for cirrus, bochs, qxl, and vmware emulation in the guest
kernel.  I wonder if I missed something.  I also emerged the
corresponding X drivers.  vmware was a pain because I had to rebuild mesa
and other stuff to emerge the vmware video driver.

  File-attached are Xorg logs for failed attempts with vga=
cirrus/std/vmware.  QEMU refused to start when I specified -vga qxl.
The vmware log looks like it started X properly, but it immediately
dumped me out, and gave an all-red QEMU window.  I ssh'd in from the
host to set up the next card.  I know that the all-red window was a text
console.  To reboot, I blindly typed "su -", followed by root password,
followed by "halt -p", and the QEMU session halted.

  I use the following script to boot up Gentoo on the guest.  I cycled
through all 4 cards...

#!/bin/bash
qemu-system-i386 -enable-kvm \
   -cpu host -display gtk -vga cirrus \
   -drive file=gentoo32.img,format=raw \
   -drive file=linuxswap.img,format=raw \
   -net nic,model=virtio \
   -rtc base=localtime,clock=host \
   -net user,hostname=gentoovm,hostfwd=tcp::2022-:22 \
   -m 3G -monitor stdio -name "Gentoo VM" \
   -parallel none \
