Yes.

I am using the binary. Just running it inside a container instead of a VM.

overlay fs?

Yes.

Since originally writing the post I have switched to a rootless podman container. Running it how I did before (inside a VM) would simply yield user_id=1000,group_id=1000 I think.

rw,nosuid,nodev,relatime,user_id=0,group_id=0

Thank you!

I don’t understand what you mean with the content disappearing when you mount the virtiofs on the guest - isn’t the mount empty when bound, untill the guest populates it?

Sorry I made a mistake in the original post. I wanted to say on the host instead of on the guest. My bad.

Yes, you are correct, the folder is empty until I log in insde the cloud application on the guest.

does it require local storage or support remote?

What do you mean? The cloud drive is a network drive basically. It only downloads files on demand.

if guest os is linux, nfs will probably do

This is what others have suggested and what I will probably do if the method below fails.

podman/docker seems to be the proper tool for you here

Yesterday I actually tried to spin a podman container hoping it would work but I encountered the following problem when trying to propagate mounts: https://lemmy.ml/post/22215540

Could you please assist me there if you have further ideas? Thank you :)

Keep in mind that a screwup could be interpreted by the sync client as mass-deletes

I am VERY aware of this *sweating*

This is what I have been trying for the past two days actually: https://lemmy.ml/post/22215540 Could you please assist me there if you have an idea? Thanks :)

do you need them all at the same time?

I need to access all files conveniently and transparently depending on what I need at work in that particular moment.

are they mostly the same size and type?

Hard no.

Why not NFS? Regardless, wouldn’t it be slower anyway compared to virtiofs?

I think NFS would be a better choice if I decide to go that route. Isn’t SAMBA slower and older than NFS?

strace can be very verbose and requires a lot of knowledge that i doubt i can share through comments back and forth.

No worries. Thank a lot nonetheless.

is creating an intermediary like others have commented on in this post an option?

What do you mean by intermediary? Do you mean syncing the files with the VM and then sharing the synced copy with the host?That wouldn’t work since my drive is smaller than the cloud drive and I need all the files on-demand.

It does not, hence my question.

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 :)

That would be impossible since the cloud drive is 2TB and my physical storage space is under 500GB in size.

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.

The cloud drive is mounted inside a virtual machine for security purposes as the binary is proprietary and I do not want to mount it on the host (bwrap and the like introduce a whole lot of problems, the drive doesn’t sync anymore and I have to relogin each time). I do not use the virtual machine per se, I just start it and leave it be.
