6.2. Virtual Network Interface Cards

Procedure 6.7. Creating or editing a vNIC Profile

1. Click the Networks resource tab, and select a logical network in the results list.
2. Select the vNIC Profiles tab in the details pane. If you selected the logical network in tree mode, you can select the vNIC Profiles tab in the results list.
3. Click New or Edit to open the VM Interface Profile window.
   

   Figure 6.2. The VM Interface Profile window

4. Enter the Name and Description of the profile.
5. Select the relevant Quality of Service policy from the QoS list.
6. Select a Network Filter from the drop-down list to manage the traffic of network packets to and from virtual machines. For more information on network filters, see Applying network filtering in the Red Hat Enterprise Linux Virtualization Deployment and Administration Guide.
7. Select the Passthrough check box to enable passthrough of the vNIC and allow direct device assignment of a virtual function. Enabling the passthrough property will disable QoS, network filtering, and port mirroring as these are not compatible. For more information on passthrough, see Section 6.2.4, “Enabling Passthrough on a vNIC Profile”.
8. Use the Port Mirroring and Allow all users to use this Profile check boxes to toggle these options.
9. Select a custom property from the custom properties list, which displays Please select a key... by default. Use the + and - buttons to add or remove custom properties.
10. Click OK.

Procedure 6.8. Enabling Passthrough

1. Select a logical network from the Networks results list and click the vNIC Profiles tab in the details pane to list all vNIC profiles for that logical network.
2. Click New to open the VM Interface Profile window.
3. Enter the Name and Description of the profile.
4. Select the Passthrough check box. This will disable QoS and Port Mirroring.
5. If necessary, select a custom property from the custom properties list, which displays Please select a key... by default. Use the + and - buttons to add or remove custom properties.
6. Click OK to save the profile and close the window.

Procedure 6.9. Removing a vNIC Profile

1. Click the Networks resource tab, and select a logical network in the results list.
2. Select the Profiles tab in the details pane to display available vNIC profiles. If you selected the logical network in tree mode, you can select the VNIC Profiles tab in the results list.
3. Select one or more profiles and click Remove to open the Remove VM Interface Profile(s) window.
4. Click OK to remove the profile and close the window.

Procedure 6.10. Assigning Security Groups to vNIC Profiles

1. Click the Networks tab and select a logical network from the results list.
2. Click the vNIC Profiles tab in the details pane.
3. Click New, or select an existing vNIC profile and click Edit, to open the VM Interface Profile window.
4. From the custom properties drop-down list, select SecurityGroups. Leaving the custom property drop-down blank applies the default security settings, which permit all outbound traffic and intercommunication but deny all inbound traffic from outside of the default security group. Note that removing the SecurityGroups property later will not affect the applied security group.
5. In the text field, enter the ID of the security group to attach to the vNIC profile.
6. Click OK.

Procedure 6.11. User Permissions for vNIC Profiles

1. Click the Networks tab and select a logical network from the results list.
2. Click the vNIC Profiles resource tab to display the vNIC profiles.
3. Click the Permissions tab in the details pane to show the current user permissions for the profile.
4. Click the Add button to open the Add Permission to User window, and the Remove button to open the Remove Permission window, to change user permissions for the vNIC profile.
5. In the Add Permissions to User window, click My Groups to display your user groups. You can use this option to grant permissions to other users in your groups.

Procedure 6.12. Configuring the Custom Device Property

1. On the Red Hat Virtualization Manager, configure the vmfex custom property and set the cluster compatibility level using --cver.

   # engine-config -s CustomDeviceProperties='{type=interface;prop={vmfex=^[a-zA-Z0-9_.-]{2,32}$}}' --cver=3.6
   

2. Verify that the vmfex custom device property was added.

   # engine-config -g CustomDeviceProperties
   

3. Restart the engine.

   # systemctl restart ovirt-engine.service
   

Procedure 6.13. Configuring a vNIC Profile for UCS Integration

1. Click the Networks resource tab, and select a logical network in the results list.
2. Select the vNIC Profiles tab in the details pane. If you selected the logical network in tree mode, you can select the vNIC Profiles tab in the results list.
3. Click New or Edit to open the VM Interface Profile window.
4. Enter the Name and Description of the profile.
5. Select the vmfex custom property from the custom properties list and enter the UCS port profile name.
6. Click OK.
