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

apt install libguestfs-tools

# 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
