<qyliss> And now I mounted it in another VM over virtio-fs!
<qyliss> So non-boot filesystem isolation isn't looking too bad
<IdleBot_f5e87eb2> This is in the model where you have host touch all the filesystems as filesystems, if only via 9p and virtio-fs?
<qyliss> Yeah
<qyliss> Every other model is a simpler version of this, so if this works, I can be pretty sure that direct guest<->guest 9p would also work for example
<IdleBot_f5e87eb2> Well, guest-guest virtio-fs is probably trickier
<qyliss> Not really!
<qyliss> As long as you don't want DAX, which is out of the question
<qyliss> Might have to write a program that proxies virtio-fs/FUSE over a network connection, but that would be very easy if it doesn't exist already
<IdleBot_f5e87eb2> Without shared cache it is unclear if virtio-fs provides actual benefits over in-kernel 9p mount
<qyliss> agree
<qyliss> So for guest<->guest 9p would probably be fine
