Hi Mark,

Out of interest, did you uninstall your old Xen before building a new one?
Sometimes the code of different Xen versions conflicts, which can mess things
up unless the previous copy was properly uninstalled.  This is especially a
problem with the tools.

When i tried to boot any domU on the newly compiled xen 3.1, it won't boot either, giving the same error. This time i took your advise and removed the previous xen rpm's. And yes as you mentioned that removed the error. However it removed virt-manager and all other stuff as well, guess i can't use them without the xen 
3.0.3.

Nowever even trying to boot my old domU, it won't give me that error, however it won't boot as well. When tried, it will show me the grub screen, and the countdown to boot, however once the countdown is  finished, it will just hang there.

Here is the /var/log/xen/xend.log snippet when the domU was tried to be booted.
