When using pre-built images to boot XEN with the ZCU106 PetaLinux BSP, a kernel panic is observed:

This is due to the CMA memory reserved for VCU OOB functionality.
1) Adjust the CMA size to 256MB from the 1000MB default by adding cma=256M to the kernel command line args.
2) Increase the DOM0 memory to 1.2G from the 768M default.
