Hi all,

I am trying to get kernel to run within a domU and am in need of some help.  Here is my current setup/status:

-Successfully boot Xen 4.0.1 with in dom0
-Can successfully boot kernel in domU and in domU

The reason I need to get to run in domU is so that I can test out Remus fault tolerance (and I don't have the ability to run HVMs on my current machine). 

I used mercurial to clone what I think is the latest version of from pointers on the Xen wiki.

A few questions:

1. Should this configuration (of dom0 and domU) work in principle?
2. Does anyone have a sample .config file that might work for 2.6.18.x (64-bit Intel machine).  I've tried using my others as a starting point, but when I try to boot the domU, it gives the following errors:

PCI: Fatal: No config space access function found i8042.c: No controller found
error getting signalfd
udevd[261]: error getting signalfd

udevadm[331]: error sending message: Connection refused

plymouthd: ply-keyboard.c.450: ply_keyboard_add_input_handler: Assertion 'keyboard != ((void *)0)' failed


I also see:
FATAL: Module scsi_wait_scan not found

Any advice would be greatly appreciated.  I've done all that I can think of based on reading various (many!) posts online.

Note that my newer .config files (e.g., for 2.6.32.x) have CONFIG_XEN_KBDDEV_FRONTEND set.  I can't seem to find a way to set this when using "make menuconfig" to build kernel  Not sure if this is relevant.
