Install default setup in ubuntu when ran into UTM, qemu based virtualization

utm_basic_install.sh

#!/bin/bash
# Install prerequisites
sudo apt install -y ubuntu-desktop
sudo apt install -y qemu-guest-agent, spice-vdagent, spice-webdavd, davfs2

# Check if spice vdagent is enabled to get right click/clipboard working through utm
sudo systemctl start spice-vdagent
sudo systemctl enable spice-vdagent
sudo systemctl status spice-vdagent

# If you want to use webdav (not recommanded) you can check if it is working with
# sudo systemctl start spice-webdavd.service
# sudo systemctl enable spice-webdavd.service
# sudo systemctl status spice-webdavd.service
# Check directory sharing through webdav, ie once SPICE WebDAV is installed and running, you should be able to access http://127.0.0.1:9843 from inside the guest. This is a WebDAV share that you can mount using something like davfs2.

# We'd rather use VirtFS, faster, and easier to setup (see https://docs.getutm.app/guest-support/linux/#virtfs)
mkdir /home/gnthibault/shared
sudo mount -t 9p -o trans=virtio share /home/gnthibault/shared -oversion=9p2000.L
# Automate with
echo "share        /home/gnthibault/shared 9p      trans=virtio,version=9p2000.L,rw,_netdev,nofail 0       0" | sudo tee -a /etc/fstab
