I tries the following without success:

1. 'con=pts' instead of 'con=pty'.
2. 'con=xterm' instead of 'con=pty'.
3. added 'init=/bin/sh' to both of the above.
4. compiled the guest kernel again with 'make defconfig'.
5. moved away /lib/tls in the guest fs.

I'm still getting the same warning about the console. When I try
with xterm it just opens and immediately closes the xterm and
I don't have a chance to see what's there.
