[Qemu-devel] [PATCH 00/17][RFC] virtio-9p: paravirtual filesystem passthrough

[Anthony Liguori]

This patch series adds a paravirtual file system passthrough mechanism to QEMU
based on the 9P protocol.  This an RFC series with a few known issues.  Right
now, all I/O is implemented in the VCPU thread.  We've modified the protocol
handlers so that we can support dispatch I/O in a thread pool but we wanted to
send out the series for initial review before completing that work.

We also do not have a very good mechanism for specifying the share path.
Suggestions would be welcome here.

This patch set should work with any recent Linux kernel as virtio-9p has been
supported for a few kernel releases now.
