BCC'ing xen-devel, since this is clearly a xen-users question at the moment.

It's not 100% clear here -- did you get the same result (Grub says
it's booting Xen then hangs) for both the CentOS packages and your own
build?

It looks like you got grub to attempt to load Xen, so as far as that
goes it looks like you did OK.

But there's not nearly enough information in this report to move
forward, and it looks like you've actively removed some important
information. :-)

What Linux kernel version are you using?  What version of CentOS, and
what Xen packages?  What hardware is it running on?  What does your
grub config look like?  Do you have a serial console attached?  Are
you using encryted (LUKS) disks?

Thanks,

 -George
