This one is weird. You should have two consoles, one of them is hvc0

Try this :
- remove (or mark) those two lines
- setup domU's /etc/inittab to spawn login prompt on hvc0

In my last testing, 2.6.30 somehow won't work (similar simptom as
yours) if I enable Xen frame buffer. If I disable it (comment out vfb
line) it works fine on Xen serial console, so perhaps it the same

If you know that 2.6.18 kernel works, why not use that for domU

doesn't even have to be the same OS.
