KVM VM Rename and Logical Volume Rename

November 5, 2012
1 min read

I recently provisioned a Virtual Machine in a KVM Hypervisor with a typo in the name. Even worse I also created the storage LV with a typo. Here is how I fixed it. Off course shut the VM down first.

LV Rename

  Renamed "oldLVname" to "newLVname" in volume group "VolumeGroup"

Change reference to storage in VM XML

Domain oldVMname XML configuration edited.


# grep newLVname oldVMname.xml
      <source dev="/dev/VolumeGroup/newLVname"></source>

Recreate VM

# virsh undefine oldVMname
Domain newVMname has been undefined


# grep newVMname /tmp/newVMname.xml
  newVMname
      <source dev="/dev/VolumeGroup/newVMname"></source>


# virsh define /tmp/newVMname.xml
Domain newVMname defined from /tmp/newVMname.xml


# virsh list --all
 Id Name                 State
----------------------------------
  7 aVMname            running
  - newVMname         shut off


# virsh start newVMname
Domain newVMname started
