Method 1 – Rename KVM VM with virsh

The syntax is:
# virsh domrename {domain} {new-name}
To rename VM from foo to bar, type:
# virsh shutdown foo
Domain foo is being shutdown

Now rename a VM, run:
# virsh domrename foo bar
Domain successfully renamed

Start a VM/domain, enter:
# virsh start bar
Domain bar started

Method 2 – Rename KVM domain with virsh

First get domain information in XML and save it to a new file:
# virsh dumpxml foo > bar.xml
Edit the XML file and change the name between the <name></name>
# vi bar.xml
Update it as follows from foo to bar:

<name>bar</name>

Shutdown the foo domain/vm:
# virsh shutdown foo
Domain foo is being shutdown

You need to undefine the old VM name:
# virsh undefine foo
Domain foo has been undefined

Finally, import the edited XML file to define the VM bar:
# virsh define bar.xml
Domain bar defined from bar.xml

Start the domain bar, enter:
# virsh start bar
Domain bar started

    Thanks for the post. I wouldn’t have discovered “virsh domrename” otherwise which is soooo much easier!

      Apparently this useful domrename is not always available – at least not in the CentOS 6 or 7 platform so far, where I have KVM environments. But the alternate procedure works quite fine.
      (Or may I be looking in the wrong place for it?)
      Thanks!

    “Edit the XML file and change the name between the ”

    I would not recommend this.
    It is much safer to

    virsh edit

    That will land you in vi too, but the difference is, if you have a typing error, no changes will be saved.
