6. Create a virtual machine using the Virtual Machine Manager utility and install the
RHEL 6.x operating system on the VM.
7. Shut down the VM.
8. Reload the newly installed Ethernet driver in the host (hypervisor) with the number
of VFs/PF as module parameter, where “X” is the number of VFs per PF:
rmmod be2net
modprobe be2net num_vfs=X
The possible values are 0 to 63 per physical port. The default value is 0 (SR-IOV is
not enabled).
The total number of VFs can be distributed among available ports as required, but
each port has a maximum of 63 VFs. Table 3-5 on page 841 lists the total number of
VF counts that are supported for various adapter configurations.
