Yes, you need to remove builder, xen_platform_pci and
device_model_version, and add a kernel and ramdisk parameters that point
to the actual kernel and ramdisk that you want to use. The file should
look like:

Got it now. It's a PVH config to start, not an HVM -- different than PVHVM ...

But checking cpu,

     hwinfo --cpu | egrep "Arch|Model"
       Arch: X86-64
       Model: 6.60.3 "Intel(R) Xeon(R) CPU E3-1220 v3 @ 3.10GHz"

You CPU is perfectly capable of running both a PVH Dom0 or DomU, check:

Look for EPT and VT-d which are the main requirements for PVH.

Clear enough. Guess it's presumed in 'modern' VT-x; odd that cat /proc/cpuinfo provides no indication
