Network Interfaces—Network Interface Cards
and Software Bridges | The VM-Series on KVM supports a total of
25 interfaces— 1 management interface and a maximum of 24 network
interfaces for data traffic. VM-Series deployed on KVM supports
software-based virtual switches such as the Linux bridge or the
Open vSwitch bridge, and direct connectivity to PCI passthrough
or an SR-IOV capable adapter. If you plan to establish connectivity
using PCI-passthrough or SR-IOV, you cannot configure a vSwitch
on the physical port used for SR-IOV or PCI-passthrough. To communicate
with the host and other virtual machines on the network, the VM-Series
firewall must have exclusive access to the physical port and associated
virtual functions (VFs) on that interface. On the
Linux bridge and OVS, the e1000 and virtio drivers are supported;
the default driver rtl8139 is not supported. Open vSwitch version support: Ubuntu 14.04
LTS: OVS 1.9.3 and OVS 2.3.1 Ubuntu 16.04 LTS: OVS 2.5.0 Ubuntu 16.04 LTS with OVS-DPDK: OVS 2.5.1 CentOS/RHEL 7.2: OVS 2.5.0
For PCI passthrough/SR-IOV support, the VM-Series firewall
has been tested for the following network cards: Intel
82576 based 1G NIC: SR-IOV support on all supported Linux distributions;
PCI-passthrough support Intel 82599 based 10G NIC: SR-IOV support on all supported
Linux distributions; PCI-passthrough support Broadcom 57112 and 578xx based 10G NIC: SR-IOV support on
all supported Linux distributions; No PCI-passthrough support. Drivers: igb; ixgbe; bnx2x Drivers: igbvf; ixgbevf; bnx2x
SR-IOV capable
interfaces assigned to the VM-Series firewall, must be configured
as Layer 3 interfaces or as HA interfaces.
