So, I discovered that some devices (i.e. phone’s virtual drive with drivers), which already attached to a VM, but somehow not being used (mounted?), appears in devices menu, so, we able to reattach them again or somewhere else.
I wonder how it works? Does it work with fuse?
I found this useful, so, if we can create one vm that encapsulates all mounted filesystems, crypto containers or anything, and exposes some drives to this menu to attach them somewhere else.
I know there is the Qubes Shared Folder but in current state it doesn’t work or even builds
Here it seems to be unmounted, but the veracrypt’s utillity says otherwise and this unlocked container became system-wide exposed, so, you can attach it anywhere.
In a file manager, unmounting usually only closes the filesystem but does not close the underlying encryption layer (which, without an opened filesystem using it, now becomes available for attaching to another VM). So it’s normal that you still need to close the encryption layer through the VeraCrypt program. Confusingly, VeraCrypt also calls this operation “unmounting” because it will close the filesystem first if it is still open (meaning, you don’t actually need to unmount manually in the file manager) and then it will close the encryption layer too.
