Sorry if this has been discussed before, but did you consider doing all
this in qemu rather than Xen?

Unless there are frequent accesses to these things then qemu would be
the default best place for this sort of thing, especially since as
you've observed there is some pretty complex memory management and
string handling which it would generally be better to avoid in the
hypervisor.

Your description of HVM_PARAM_VMPORT_RESET_TIME suggests they aren't
typically accessed very frequently.

Ian.
