Scenario

Procedure

  1. In the VM OS, enter the (CLI) mode and run the su root command to switch to user root.

  4. Enter ?DHCLIENT_SET_HOSTNAME to locate the configuration item to be modified.

  5. Enter ?DHCLIENT_USE_LAST_LEASE to locate the configuration item to be modified.

    Press i to enter the editing mode, and set the value of the configuration item to no so that the fallback to the last lease is disabled.
