To rename a KVM virtual machine (VM) domain using the virsh command, you can use the following steps:
virsh list command:virsh list
This will display a list of all the current domains and their IDs.
virsh dominfo command to display information about the domain:virsh dominfo domain_id
Replace domain_id with the ID of the domain you want to rename. This will display information about the domain, including its current name.
virsh setmaxmem command to set the maximum memory limit for the domain to its current value:virsh setmaxmem domain_id current_memory --config
Replace domain_id with the ID of the domain you want to rename, and current_memory with the current memory limit of the domain, as shown by the virsh dominfo command. The --config option tells virsh to modify the configuration file for the domain, rather than modifying the running domain.
virsh setname command to set the new name for the domain:virsh setname domain_id new_name --config
Replace domain_id with the ID of the domain you want to rename, and new_name with the new name you want to give the domain. The --config option tells virsh to modify the configuration file for the domain, rather than modifying the running domain.
virsh edit command to edit the configuration file for the domain and change the name in the <name> element:virsh edit domain_id
Replace domain_id with the ID of the domain you want to rename. This will open the configuration file for the domain in your default text editor. Find the <name> element and change the value to the new name you want to give the domain. Save the file and exit the editor.
virsh destroy command to shut down the domain:virsh destroy domain_id
Replace domain_id with the ID of the domain you want to rename.
virsh start command to start the domain with the new name:virsh start domain_id
Replace domain_id with the ID of the domain you want to rename.
This will rename the KVM virtual machine domain using the virsh command.
