If you load a FreeBSD VM into KVM, and turn on host-guest sharing, you'll see a VirtIO function for Plan 9's v9fs exposed on the PCI bus. This speaks a Linux-specific variant of the 9P protocol, 9P2000.L. FreeBSD currently does not understand how to talk to it, nor do our existing 9p ports. BHyve doesn't support host-guest sharing (yet). Note: I neither claim nor argue that this is the most efficient host-guest solution -- there are anecdotal reports that the claims IBM have made in published papers cannot be verified in production -- but it makes sense to re-use (and perhaps improve upon) what IBM have done here, for the sake of interop more than anything else. There is a FUSE-based implementation in Python, py9p, which might serve as the basis for a prototype. NetBSD have a newer alternative but it looks like more work to make it talk to the VirtIO function. -- BMS (sent via webmail) _______________________________________________ svn-src-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
