In order to have the guest agent installed correctly, follow these steps:
Go to <virtio_cd>\guest-agent and install the agent for your system
Reboot the VM
Open Device Manager (Start->Device Manager)
For ANY unknown device (showing the little warning icon ⚠), right-click on it, Update Driver, Browse my computer for drivers
Select the virtio_cd mounted CD drive and make sure Include subfolders is checked and click next.
Windows should automatically find the correct driver and install it for you.
For Linux (Bazzite specifically), this is what I did:
Open a terminal
write sudo rpm-ostree install qemu-guest-agent. if you get a message saying error: "qemu-guest-agent" is already provided...You can continue to the next step
Write sudo systemctl enable --now qemu-guest-agent.service to start the service immediately and tell it to run on boot
That's it! You should see a ...is added as a dependency... message
