First of OSv comes with a simple VGA console driver that allows apps like
rogue run (see apps/rogue).
As far as X11 apps I had not tried to run them before you asked so I had no
idea they would work. So I actually spent some time playing with some of
the simple ones and I got many of those to function on OSv after applying a
small patch which I show later. I tried the following apps: xclock, xeyes,
xlogo, xcalc and they seemed to work after I configured my host - Ubuntu
19.04 - to accept X11 connections over TCP (which is slower than local
socket - I wonder it vsock would work better here) and let unauthorized
traffic using xhost+.
Running chrome I think would be more complicated as it uses GPU
acceleration (you can disable it though) and more importantly forks itself
for each open tab and OSv does not support fork(). New virtio 1.1 spec
defines GPU device but I am not sure how well supported it is and somebody
would need to implement the driver for OSv,
Here is a hacky patch to the networking layer (I need to understand why
this assert fails):

If you are are interested in more details on how to try some of the apps
let me know.
