7. Choose the number of CPUs that will be used by the partition. You have to
decide whether to use dedicated or shared CPUs. When a dedicated CPU is
used, no load can be moved to other currently free CPUs because this may
lead to a performance issue. In Figure 6-18 you see that we configured two
CPUs and shared processor mode. Click Next to proceed.

8. Depending on the setup of the network in the BladeCenter chassis and in the
Virtual IO Server, you may have different settings. When you define host
Ethernet adapters to the partition then no Ethernet bridge in the Virtual IO
Server is required. The disadvantage is that you are not able to use partition
mobility. For partition mobility it is a requirement that the partition be
configured with virtual Ethernet adapters. The Ethernet bridge is configured in
the Virtual IO Server. For more details about this see 4.5.2, “Virtual Ethernet
Adapters and SEA” on page 103.
