Resize KVM (qemu) disk
On host machine: To expand the size of the image, we would run the following command: $ qemu-img resize disk1.qcow2 30G As an alternative, instead of the absolute size, we could specify the size increment: $ qemu-img resize disk1.qcow2 +10G On guest linux operating system: Using gparted extend the partition with the additional space. Or growpart /dev/xvda 1 # Grows the partition size resize2fs /dev/xvda1 # Grows the filesystem ( growpart is part of cloud-util )
