[9fans] xen -> direct 9p channel

[Enrico Weigelt]

Hi folks,

I've found some discussions about an direct 9P channel in xen
(so all devices can be served from dom0 via 9P, w/o hw emulation).
Does anyone know some bit more about this ?

it's an ericvh and lucho project, and it will be very nice when done!

the code is in the kernel, if you want to hack, start with lguest
because they're all the same devices in the end.

This was done in the context of an internal IBM project with a now
ancient version of Xen.  There was some share memory support added to
Inferno so it could act as a server.  Until recently these were
available in my home machine's Inferno repository.  A system reinstall
later and those public repositories are gone, but I should still have
the code in my IBM repositories.

However -- the better approach here would be to use virtio, but I'm
not what the current Xen stance is on virtio.  All that being said,
you'd probably be better off looking at KVM or lguest versus Xen for
Plan 9 hosting (which support virtio).
