View source for Changing security groups (Advanced Console)

'''This article will explain how to change an existing virtual machine/instance's or network port's security group.'''

Sometimes you may want to change which network security group a virtual machine/instance belongs to, or change an individual network port's security group membership. Changing security group membership will change what ports an instance can communicate over.

== Change an instance security group ==
If an instance only has a single network port, or if you want all network ports connected to an instance to be in the same security group, you can change the security group easily with these steps.

First, login to the [https://cloud.datatenant.com DataTenant Cloud]. Navigate to the Project, Compute, Instances menu.

== Change a network port security group ==
If your instance has multiple network ports, and you want different ports to have different security postures, you can edit each network port's security group membership individually.

To begin, follow the steps from the previous section, but in the 'Actions' menu, choose 'Edit Port Security Groups' instead.

In the 'Interfaces' screen, you will see all of the network ports attached to your instance. Click on 'Edit Security Groups' for any available network port to be brought to a screen where you can edit the port's security group membership. Save when completed.
