[Xen-users] xen 4.1.3, EFI boot and "no console to OS" problem

Hello All!

I have a new OpenSuse 12.2 (with 3.4.33-2.24-xen kernel) + Xen 4.1.3 install on an IBM x3550 server. The system is booted via EFI with Grub2 bootloader and it boots up normally, either with or without Xen.
But i have one trouble with it: I can't get console access working with Xen.

The strange thing is, despite the "WARNING: no console will be available to OS" appearing during xen loading, the console actually starts, the graphical login screen does even appear... and then freezes. Just the console; the system iself continues to run normally.
Booting the system up without xen leaves also the console working.

Yet i do need this console: after some testing i have to implement this new Suse/Xen install on a distant server (which has a management module for remote console access) and I just can't risk being blinded and cut off in case there will be some confusion with network interfaces, for example.

Some googling on this matter didn't give any help also. It did reveal some opinions, though, suggesting that this console problem is related to EFI.. but, unfortunately, nothing useful.

Can anyone please tell me if/how it's possible to get console access with Xen 4.1.3 and EFI boot? And if not, what would be the closest solution? Xen 4.2?, Xen 4.1.2?, ELILO?

With best regards,
