Renaming a KVM virtual machine

1. View all KVM virtual machines

2. Renaming a KVM virtual machine is best to shut down the virtual machine before exporting its XML file

[[Email PROTECTED]_KVM ~]# cd/etc/libvirt/qemu[[email protected]_kvm qemu]# virsh dumpxml  > Kvm_00.xml

3, in order to let the renamed virtual machine name and disk file name consistent, we can first name the previous disk file to Kvm_00.img

[Email PROTECTED]_KVM ~]# cd/var/lib/libvirt/mv kvm_client00.img kvm_00.img        // Renaming a virtual machine disk file name

4. edit Kvm_00.xml file, modify <name> tag pair and disk File , here we change the disk file into kvm_00.img

<domain type='KVM'> <name>kvm_00</name>      ......     ... The omission of .....<disk type='file'Device='Disk'> <driver name='Qemu'Type='Raw'Cache='None'/> <sourcefile='/var/lib/libvirt/images/kvm_00.img'/>

5. Use the Virsh undefine command to delete the previous virtual machine and define a new KVM virtual machine based on the new XML file

[[Email PROTECTED]_KVM ~]# virsh undefine kvm_client00                // Delete kvm_client00 virtual machine [email protected]_ KVM ~]# virsh define/etc/libvirt/qemukvm_00.xml   // redefine a new KVM virtual machine

6. Finally we can use the Virsh List--all command again to view the results as follows:

The KVM machine, renamed as above, can be started directly, without affecting the files of the Udev dynamic management device. Compared to the previous virtual machine, just the name changed.
