Updated to CentOS-6.6, but I still get the same issue.

By the above I assume you're using the xen4 repo rather than the xen-c6 repository referred to by http://wiki.centos.org/QaWiki/Xen4?
Is the xen-c6 repo now considered broken or deprecated with the xen4 repo used in preference?

The same hardware (cluster of 10 machines) was successfully working with the xen-c6 repository previously; I'm not sure what issue might have occurred to cause this failure on all hosts which is why I think it's a software issue.  Possibly a driver issue although the last successful run was using the same kernel so I assume had roughly the same drivers installed.  Note that the 3.4 kernel boots fine without Xen, it is only under Xen that the boot fails and the machine restarts.
