Example of using virtio network interfaces from application code

Hi, Is there a good example that uses the virtio network interfaces direct? ie. an application that uses ‘assign-net’ and talks directly to the network interface code in OSv? I’m looking for a sample I can learn from. Cheers, Rick -- You received this message because you are subscribed to

Is there an equivalent to SO_BINDTODEVICE? I’m trying to get an implementation of VRRP working and the first issue is that the sending socket requires to be bound to the appropriate interface. After that, I’ll probably run into issues relating to the virtual IP and mac address - but the
