Some quick notes on setting up a shared folder between a host computer and a virtual machine Manager (and VM dependencies) - Install virtiofsd to allow shared folders between host and guest. This may just be a path: Some reasonably meaningful string; I chose host-share - Finish setup and installation - In the VM, allow mounting the share. - Pick a mountpoint (it doesn't need to already exist). I chose /home/USER/vmshare.

Create a folder somewhere for sharing. I chose /home/USER/vmshare.

Create a virtual machine, using Debian 13 for both host and guest. This is great if you're working with untrusted files and want a safe place to work with them. (Another option is something like magic-wormhole, if network access is permitted.)

The only really unintuitive thing is the virtiofs "target". I thought this was supposed to be a VMM UI bug.

On host:

• Install virt-manager for the actual Virtual Machine:

• Use Debian 13 live/installer ISO

• Configure:
  • Memory: Enable shared memory
  • Add Hardware: Filesystem
    • Driver: virtiofs
    • Source path: /home/USER/vmshare.
