Hi, Is there any zero-copy VM memory access API in libvirt? I see only virDomainMemoryPeek function, which copy some memory from VM and do not permit VM memory modifications. What I'm looking for is xen xc_map_foreign_pages or xc_gnttab_map_domain_grant_refs equivalent/wrapper. IOW map memory pages to dom0 address space, without copy. I know that not every hypervisor supports it, but it is useful to build a high-performance communication channel on top of it.
