Hi,

Ah, I see, here is the xen reset vector dependency.
I'm wondering whenever there are plans for cloudhv to also support sev
and/or tdx some day. If so, then it probably isn't a good idea to
switch to the xen reset vector. There is the work area used for by
confidential computing code, I think it would be an option to store a
pointer to the pvh_start_info there.
take care,
Gerd
