The fact that /sbin/start_udev doesn't work is obviously a problem.

Does the script exist?  Does it run?  Does it give errors?

It exists, it runs, it fails silently. The only output from "/sbin/start_udev || echo foo" is "foo".
 Are you
capturing all the errors when the init script runs?  Have you tried adding 'set +x' to your init script?Are you using the full start up method shown in libguestfs's appliance/init?

No, I have exactly the init that you had in your blog post. I'm mounting /sys and then running /sbin/start_udev manually.

See: http://fedoraproject.org/wiki/Features/VirtioSerial


/sys/class/virtio-ports/vport0p1 and its contents are there after I mount /sys, so that's a good sign, I guess.
