You should probably contact OVM support.

The domain keeps crashing. Xend will retry it a few times but will
eventually give up rather than just keep banging its head against the
wall.

Unfortunately there is no clue as to the reason for the crash in the
logs etc which you have shown here. Perhaps there was something a bit
earlier in the log?

Otherwise you could try adding 'on_crash = "preserve"' to your domain
configuration and see if that lets you see anything e.g. on the VNC etc.
You should also check all the files under /var/log/xen and the xen dmesg
("xm dmesg") for clues. The OVM support guys can likely also direct you
on OVM specific places to look etc.

Ian.
