How to Prepare a Domain With an SR-IOV Ethernet Virtual Function for Migration

When you create an SR-IOV Ethernet virtual function or assign it to a guest domain, you must ensure that the virtual function has a user-assigned virtual function name by specifying it as the name property value.

In addition, the domain to be migrated must be configured with a multipath route for the SR-IOV Ethernet virtual function and a virtual network device. Both of these virtual interfaces must be able to access the same network.

1. Ensure the SR-IOV Ethernet virtual function is associated with a user-assigned virtual function name.
   • New SR-IOV Ethernet virtual function: Create the virtual function with the user-assigned virtual function name.

     source:primary# ldm create-vf name=user-assigned-name pf-name

   • Existing SR-IOV Ethernet virtual function: Associate the user-assigned virtual function name with the virtual function.

     source:primary# ldm set-io name=user-assigned-name vf-name

2. Assign the SR-IOV Ethernet virtual function to the guest domain.

   source:primary# ldm add-io vf-name guest-domain

3. Create an active-standby IPMP group for the SR-IOV Ethernet virtual function and the virtual network device.

   The SR-IOV Ethernet virtual function is the active interface and the virtual network device is the standby interface.
