BIG-IP may not be able to its their licensed throughput limit on VE guests with SR-IOV interfaces. In this situation a subset of the guest CPUs will report 100% cpu usage when measured from the command line with the 'top' command.
Virtual Edition guests with SR-IOV interfaces may exhibit throughput lower than the licensed limit.
11.5.0-release VE guests with SR-IOV interfaces on Xen, VMware, and KVM hypervisors.
There is no known workaround. Switching an 8-core guest to a 4-core guest may slightly improve throughput.
