how to map a host virtual address (hva) to guest address space (gva/gpa/gfn)

[sheng qiu]

Hi all,

is there any existing function in KVM that can map a host virtual
address (hva) to the guest address space. So that the guest VM can
access it.
i.e. translate hva to a gpa or gva or gfn, so the guest VM can use
that converted address to access?

Thanks,
Sheng
