i had a similar question since i've been happy with p9fs.  the virtiofs 
faq states (https://virtio-fs.gitlab.io/):

"Existing solutions to this problem, such as virtio-9p, are based on 
existing network protocols that are not optimized for virtualization use 
cases. As a result they do not perform as well as local file systems and 
do not provide the semantics that some applications rely on.

Virtiofs takes advantage of the virtual machine’s co-location with the 
hypervisor to avoid overheads associated with network file systems."


that seems super reasonable to me.  i also think there is windows 
support for virtiofs which is probably another benefit.
