Again, how?

If you didn''t use proper methods to do either, it''s not
surprising
that it won''t work.

Are you using "kernel" line in domU xen config file? Usually
that''s
not what you want.

... especially since newer kernels won''t even have "hda".
sda, maybe.
usually it''s xvda. And it doesn''t look like you use initrd.

... and your incorrect settings cause the domU crashed after loading the kernel

... which made xen refuse to restart it.

These instructions might still be valid:
wiki.xen.org/wiki/RHEL6_Xen4_Tutorial
In particular, if you''re having problem determining what the correct
domU config file should look like, virt-manager will help automate the
process.
