Yes.  I removed support for '-c' in vm-create in favor of doing it at 
the vm script level.  It just doesn't make sense for vm-create to be 
exec() another process.

You're missing the "root=" part of the command line.  It should be:

# vm-create /boot/vmlinuz-2.6.9-xenU -m 96 -C "root=/dev/hda1 ro" 
--attach-vif=aa:00:00:02:00:00 -B 0707:0301

This means your system started up properly.  While I do not like the 
fact that libxc dumps out to stdout a lot I have to admit it's very 
useful :-)

I very recently fixed the buffering problems in vm-console.   They 
probably didn't make the last release.  I'm planning on updating latest 
this evening.  vm-console was accidently flushing the tty when it opened 
it up.  The output you should be seeing is a VFS error from the kernel.
