The problem is that this image is incompatible with virt-resize: $ virt-builder ubuntu-20.04 $ virt-filesystems -a ubuntu-20.04.img --all -l -h Name Type VFS Label MBR Size Parent /dev/sda1 filesystem vfat - - 511M - /dev/sda5 filesystem ext4 - - 5.3G - /dev/sda1 partition - - 0b 512M /dev/sda /dev/sda2 partition - - 05 1.0K /dev/sda /dev/sda5 partition - - 83 5.5G /dev/sda /dev/sda device - - - 6.0G - Note the root filesystem is on a logical partition (/dev/sda5) which virt-resize cannot handle: https://libguestfs.org/virt-resize.1.html#logical-partitions I wonder if there's a way to make Ubuntu templates that don't use logical partitions?
