Advanced Storage and Networking Features - Getting Started with Red Hat Enterprise Virtualization - page 128

Now we can use the created QoS profile and attach it to a VNIC, also known as a Virtual
Machine ( VM ) interface profile. Starting with Red Hat Enterprise Virtualization 3.3,
when you create a new logical network from the manager, a VNIC profile of the same
name as the logical network is automatically created under that logical network. We can
also create multiple VNIC profiles, and apply those profiles to respective virtual ma-
chines.
To create a new VNIC profile, perform these steps:
1. Log in to the Administrator console and navigate to the Networks resource tab.
2. Select the appropriate logical network and click on the Profiles tab in the bottom
pane.
3. Click on New and this will open a new VM Interface Profile window.
4. Insert some meaningful content in the Name and Description fields, and select
the QoS profile you created from the drop-down menu.
5. Optionally, one can enable the Port Mirroring option; this will copy layer 3 net-
work traffic on a given logical network and host to a virtual interface on a virtual
machine, which can be used for network tuning, debugging, and more.
6. Finally, enable or disable Allow all users to use this Profile , and click on OK to
save this profile and close the window.
