I started udev with /sbin/start_udev, as in the init script, but that seems
to have no effect ("ps aux | grep udev" gives me no output.)
The fact that /sbin/start_udev doesn't work is obviously a problem.
Does the script exist? Does it run? Does it give errors? 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?
If I start the
guest with
qemu-kvm -kernel kernel -initrd initrd -hda root -device virtio-serial
-serial stdio -chardev
socket,path=/home/uckelman/projects/lightbox/supermin/foo,id=channel0
-device virtserialport,chardev=channel0,name=org.libguestfs.channel.0
what should I expect the device connected to the pipe on the guest side to
be called?
/dev/virtio-ports/<name>
