Virtualization: How do I share a cloud drive mounted inside the guest with the host? (x-post from [email protected])
Because the executable is proprietary (and a bit legacy I would say) and full of telemetry, undocumented and the cloud service has no CLI, WebDAV or rclone support. I do not want to run something like that on my personal computer and I do not know how to use bwrap properly and don't want to risk it. I have since switched over to a podman container but I encounter the same problem, the folder is empty on the host (See my post here: https://lemmy.ml/post/22215540).
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

Fair. I will try NFS if anything else fails. Thanks :)

I strongly disagree why this would not be beneficial. Could you expand?
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:

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 :)
Access cloud drive mounted inside container from host (Bind/Mount propagation)
Hi everyone! I want to be able to access a (fuse-type) cloud drive mounted inside a container as the binary is proprietary and I do not want to mount it on the host for security and privacy purposes. I have tried to quickly spin a podman container and bind the folder that corresponds with the drive with the rshared flag but the folder appears to be empty on the host while inside the container it works just fine.
I am running the following commands:
undefined
$ podman unshare mount --make-shared --bind /clouddrive /clouddrive
$ podman run -i -t --cap-add=sys_admin --network host \
--security-opt label=type:container_runtime_t \
-v /cloudbinary:/bin/cloudbinary:ro \
-v /clouddrive:/clouddrive:shared \
--device /dev/fuse:/dev/fuse \
-v /bin:/bin:ro \
-v /lib64:/lib64:ro \
--privileged --name=name image /bin/bash
Inside the rootless container I run:
undefined
# cloudbinary login username <enter password> <successful login> # ls /clouddrive file1 file2 file3
But on the host `/clou
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.

What would be the performance implications? Isn't virtiofs theoretically faster?

Every other solution looks more elegant on paper but has lots of pitfalls
A very sane and fair comment.
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 :)

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

Hi everyone! I want to be able to access a folder inside the guest that corresponds to a cloud drive that is mounted inside the guest for security purposes. I have tried setting up a shared filesystem inside Virt-Manager (KVM) with virtiofs (following this tutorial: https://absprog.com/post/qemu-kvm-shared-folder) but as soon as I mount the folder in order for it to be accessible on the guest host the cloud drive gets unmounted. I guess a folder cannot have two mounts at the same time. Aliasing the folder using bind and then sharing the aliased folder with the host doesn't work either. The aliased folder is simply empty on the host.
Does anyone have an idea regarding how I might accomplish this? Is KVM the right choice or would something like docker or podman better suited for this job? Thank you.
