Configure Para-Virtualization Without Live Migration

1. Using VM, assign the MAC address to the bridge that the NEM port has been assigned.

   This MAC address will be used in the guest's OS as the virtual port of the NEM.

   Alternatively, you can assign the MAC address by editing the vm.cfg file using XEN.

   Example: To edit vm.cfg file to set eth4 as the NEM port, you would enter the following in the file:

   vif = ['type=netfront,mac=00:14:4F:85:BE:8f,bridge=eth4']

2. Log in to NEM using the CMM CLI. See Start NEM CLI from CMM ILOM CLI.
3. Set each MAC address to the NEM port that will be used as the para-virtualized port, based on the firmware version:
   • For version 1.040 or older:

     set -b x -p y -f z -m xx:xx:xx:xx:xx:xx

     where

     
     

     x is the blade number (0-9) running Oracle VM guests y is the NEM port number (0 or 1) assigned to the Oracle VM guest z is always 0 for the para-virtualization environment xx:xx:xx:xx:xx:xx MAC address (the same MAC address that you assigned to the guests using Oracle VM or by editing the vm.cfg file

     For example, if NEM port 0, which is eth1 in the DOM0, is assigned the MAC address of 00:21:28:40:38:FE for blade 3, you would enter the following command:

     set -b 3 -p 0 -f 0 -m 00:21:28:40:38:FE

     ---

     Note - Only 15 VM MAC addresses (including bonded MAC addresses) can be configured per NEM port.

     ---

   • For version 1.050 or newer:

     set -b x -p y -f z -m 00:11:22:33:xx:xx

     where

     
     

     x is the blade number (0-9) running Oracle VM guests y is the NEM port number (0 or 1) assigned to the Oracle VM guest z is always 0 for the para-virtualization environment 00:11:22:33:xx:xx is the MAC address (the same MAC address that you assigned to the guests using Oracle VM or by editing the vm.cfg file

     For example, if NEM port 0, which is eth1 in the DOM0, is assigned the MAC address of 00:21:28:40:38:FE for blade 3, you would enter one of the following commands:

     set -b 3 -p 0 -f 0 -m 00:21:28:40:38:xx

     Or

     set -b 3 -p 0 -f 0 -m 00:21:28:40:xx:xx

     ---

     Note - The last two bytes of a MAC address are used as mask bits that allow you to use up to 64K MAC addresses per NEM port per blade. For example, from 00:11:22:33:00:00 to 00:11:22:33:FF:FF.

     ---

4. Disable promiscuous mode on the blade's port that is assigned to the guest. See Promiscuous.
5. Disable SR-IOV mode. See SR-IOV.
6. Repeat Step 3 to Step 5 for each port of each blade.
