virsh^[1]^[2] is a command line utility for managing virsh guest domains/virtual machines and the hypervisor^[3]. Can be used to operate vm like create, list, start, shutdown or suspend and to manage storage, snapshots and checkpoints^[4] among other actions. virt-manager is a graphical alternative to virsh. It supports Xen, QEMU, KVM, LXC, OpenVZ, VirtualBox and VMware ESX.

virsh is include in libvirt-client package in RHEL and Ubuntu and uses libvirt management API. Binaries included:
