VM-Series on KVM— Requirements and Prerequisites
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.
Data Plane Development Kit (DPDK) Support
DPDK is enabled by default on VM-Series firewalls on KVM if one of the following NIC drivers is used:
