That doesn't sound optimal to me.
So, let's clarify things first: those Isolation VMs - are they going to
be the paravisors?
I don't see any other option because the unmodified guest must be some
old windoze....
So, if they're going to be that, then I guess this should be called
CC_ATTR_PARAVISOR
to denote that it is a thin layer of virt gunk between an unmodified
guest and a hypervisor.
And if TDX wants to do that too later, then they can use that flag too.
Yes, no?
