do you have to provide a username/password or token when you try to access the drive now?

I do but it’s through the proprietary GUI of the binary which has no CLI or API I can use.

I just checked and it is mounted as a fuse drive.

do you know how to use strace?

A very confident NO :)

Then I will try NFS and get back to you. Thanks :)

The cloud binary is proprietary and it’s not supported by rclone unless I find out how the binary works but I doubt it uses something standardized like WebDAV underneath.

I can try but I might end up in the same situation as with virtiofs. The cloud drive will get unmounted and I will end up with an empty folder when I try to access it from the host.

The cloud drive is mounted on the guest, yes, but once I mount it with virtiofs in order to share it with the host it gets unmounted and I end up with an empty folder. bind doesn’t work either.

I have no idea how it is mounted (how can I find out?) because the binary is proprietary. This is why it is contained inside a virtual machine.
