## Everything lives here
mkdir -vp /var/lib/libvirt/images/hassos-vm && cd /var/lib/libvirt/images/hassos-vm

# See netplan config below, apply with "sudo netplan apply"
# If you already have docker running, your bridge might not work as expected because it manages your iptables rules in a way which causes problems with forwarding, below command will fix that
sudo iptables -P FORWARD ACCEPT

# Install HassOS with the QCOW2 image from https://www.home-assistant.io/hassio/installation/#alternative-install-on-a-generic-linux-host
# The below command also allows you to log in using VNC, useful for debugging
sudo virt-install --name hassos --graphics vnc,listen=0.0.0.0 --memory=2048 --vcpus=2 --disk=/var/homeassistant/hassos_ova-4.11.qcow2,format=qcow2 --boot uefi --import --os-variant=debian9 --network=bridge=br0

# ------------
# ATTACH USB DEVICES (e.g. zwave)
# -----------
# See zwave.xml below for an example
virsh attach-device hassos --file usb_stick_nortek.xml --persistent

# ------------
# RESIZE IMAGE
# -----------

# The default disk size is only 5 GB, you can extend it with the commands below

# 1) Show all partitions in the QCOW2 image, you probably want /dev/sda8 but make sure you do
sudo virt-filesystems -l  -h --all -a hassos_ova-4.11.qcow2

# 2) Resize image, below will increase with 5GB
sudo qemu-img resize hassos_ova-4.11.qcow2 +5G

# 3) Make a copy of the image (required for next step)
cp hassos_ova-4.11.qcow2 hassos_ova-4.11-orig.qcow2

# 4) Resize, this might take a while
sudo virt-resize --expand /dev/sda8  hassos_ova-4.11-orig.qcow2 hassos_ova-4.11.qcow2

# 5) Check if everything went as expected
sudo virt-filesystems -l  -h --all -a hassos_ova-4.11.qcow2
