| If your OS is Ubuntu and the version is newer than 16.04, the network configuration is very likely handled by `netplan` by default. Please `Edit Config` > `Advanced Options` on your VM before creating backup, and take the following network-data as reference for DHCP configuration. |

Edit config means the VM needs to be restarted in general.
Add this hint to vm creation page too?

Yup. The VM needs to be stopped before Edit Config. I'll add to the vm creation.

| The restored VM will retain the same machine ID as the original, which will cause it to receive the same IP address from the DHCP server if `dhcp-identifier: mac` is not specified since `netplan` use machine ID as dhcp identifier by default. It is essential to configure the network-data before performing a VM backup for Ubuntu systems. Failure to do so will result in unexpected behavior and potential network conflicts. |

A further question, is it possbile to mutator the VM to change dhcp-identifier when restoring? That will benefits all users.

I tried w/o luck. They will need to modify the netplan config and do netplan apply

Thanks. I revised the backup-restore part per the suggestion and add the same in create-vm. |
