Re: RFC: Kernel virtiofs driver

Do both p9fs and virtiofs both support mmap() such that two or more guests, and the host, can all map a file on the host for read/write access, and each see writes made by the others? This is my pain point with nfs and smb.

Is either one as lightweight as zvol and ufs, such that I could consider using it for the os?

I appreciate all the effort both teams have put in.
