Hello David, Virtio-fs sounds like a natural fit for your situation. Please see this wiki page for details: https://github.com/cloudius-systems/osv/wiki/virtio-fs
In short, virtio-fs lets you mount a host directory on the guest. The OSv implementation is read-only but that shouldn't be a problem since you are using rofs currently. Feel free to check it out and of course come back if you run into any issues or have any feedback!

In my case, the filesystem type used to build the .raw image file is ROFS (selected primarily to reduce startup time). I can see the script being used to generate this filesystem image (gen-rofs-img.py), but I haven't yet seen any way in which I can unpack/mount an existing filesystem image, make changes to the content and re-pack/unmount the image. Is this a facility that is already available in some form? If not, any suggestions on the best approach would be welcome. -- You received this message because you are subscribed to the Google Groups "OSv Development" group.
