V tomto případě jde spíše o grow disk, tedy „růst“ disku. V té češtině to zní příšerně, uznávám.
Máme .qcow2 image s virtuálkou pro KVM. Jakékoliv ostatní např. instalační image jsou k dispozici zde.
Na linuxu jsem dal qemu-img resize

Device is mounted read-write; resizing will result in temporary write suspension for /.
It's strongly recommended to make a backup before growing the file system.
OK to grow filesystem on /dev/gpt/rootfs, mounted on /, from 4.0GB to 25GB? [yes/no] yes
