The following command extend the image (the hard disk in the virtual machine) with 1024 gigabytes.

qemu-img resize vm-215-disk-1.qcow2 +1024G

Ok, virtual size: 1.26 TiB

qemu-img info vm-101-disk-0.qcow2
image: vm-101-disk-0.qcow2
file format: qcow2
virtual size: 1.26 TiB (1382979469312 bytes)
disk size: 229 GiB
cluster_size: 65536
Format specific information:
    compat: 1.1
    compression type: zlib
    lazy refcounts: false
    refcount bits: 16
    corrupt: false
    extended l2: false

After reboot VM, we can see the /dev/sda : 1.26 TiB

We need extend partition 2 first and then partition 5
