Virsh Commands

From Xen
Jump to: navigation, search

The libvirt toolkit is focused primarily on KVM virtual machines, but it is intended to be usable for multiple virtualization technologies, including the Xen Project Hypervisor. As a result, some commands are essential when using Xen Project software, but others do not apply as they are targeted for KVM concepts.

Some of the essential virsh commands for manipulating Xen Project VMs include:

Common VIRSH commands:
help print help

create create a domain from an XML file
start start a previously created inactive domain

define define (but do not start) a domain from an XML file
domid convert a domain name or UUID to domain id
