Thanks for the quick response Ruben.
When I change to Kernel, One requires "Initrd", "Root", and "Kernel commands" parameters. These are not needed in my implementation using the hvmloader kernel. How do I circumvent using them or what would the appropriate values be when using hvmloader?
Thanks,
Marshall

There are a couple of difference, that can be set in the opennebula template as:
1.- Drivers, in your example all the disks are "file:" you can set that in the DISK with DRIVER (DISK=[ DRIVER="file:"...]). Default driver can be set in vmm_exec_xen.conf
2.- The target using in your file are of type xdva. You can either use TARGET in DISK (DISK=[TARGET="xvda"]) or DEV_PREFIX=xdv in your Image Templates
3.- In your example you are using kernel and not bootloader, change that in the OS attribute.
4.- The other missing parameters if needed can be specified with RAW
For further reference check the specific attributes supported for Xen [1], and the general Template definition file [2]

Good Luck
