Fotis, Thanks a lot!
I have updated this page to include the information about ARM - virtio-fs works on this arch as well which is great! The virtio-fs support is probably the single most exciting new feature added to OSv in the last couple of years! I am not aware of any other unikernel supporting it. Thanks a lot, Waldek PS. It would be nice if some other hypervisors (thinking of firecracker) supported virtio-fs as well.
