Hi Edgar,
Yes, we certainly don't want the xl parser in the hypervisor. We only
need a minimal subset of options. We do already have a device tree
parser that understands cells. We also have a parser for a set of
command line options, some of them similar to the VM options we need to
pass. I think

This hypercall allows the toolstack to present one combined CPUID and MSR
policy for a domain, which can be audited in one go by Xen, which is necessary
for correctness of the auditing.

As with the serialise side, Xen's copy_from_guest API is used, with a
