To change the hostname of an OpenVZ container, follow these steps:
1. Log into your OpenVZ Host Node. This is the server that hosts your OpenVZ containers.
1. Find the Container ID (CTID) of your OpenVZ container. You can do this by running the command `vzlist -a`.
1. Stop the container using the command `vzctl stop CTID`, replacing “CTID” with your Container’s ID.
1. Set the new hostname using the command `vzctl set CTID —hostname newhostname —save`, replacing “CTID” with your Container ID and “newhostname” with your chosen hostname.
1. Start the container with the command `vzctl start CTID`.
You have now set a new hostname for your OpenVZ container. Make sure to replace “newhostname” with your desired hostname.
