libvirt is an open source API, daemon and management tool for managing platform virtualization. It can be used to manage KVM, Xen, VMware ESX, QEMU and other virtualization technologies. These APIs are widely used in the orchestration layer of hypervisors in the development of a cloud-based solution.
qemu-img create -f qcow2 /var/lib/libvirt/images/test.qcow2 64G
qemu-img resize /var/lib/libvirt/images/test.qcow2 +10G
and then resize partition table and filesystem.
virt-install -r 4096 --accelerate -n test \ -f /var/lib/libvirt/images/test.qcow2 \ --cdrom /CentOS-6.5-x86_64-bin-DVD1.iso \ --network=type=direct,source=eth0 \ --graphics vnc,listen=0.0.0.0,password=somepass \ --noautoconsole
(connect using vnc client to server IP to finish installation)
