Hi Fabian,
Would be possible to use mmap(2) around libvmmapi to map a file (MAP_PRIVATE) and or shared memory segments (MAP_SHARED) into guest physical address space?
It currently isn't - doing that will just insert the mappings into the user process's view, and not into guest address space.
Bhyve currently uses a separate vmspace for guest address space. While this simplifies the EPT code internally, it also prevents direct manipulation of the address space using standard system calls.
A possible solution to this would be to have the ability to apply address-space manipulation calls to an arbitrary address space - this was brought up in Linux a long while back: https://lwn.net/Articles/19047/
later, Peter. _______________________________________________ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
