I have a need where I am running a virtualized OPNsense (pfSense fork) instance and have redundant gateways, thus I need two WAN ports and the man LAN port. It appears that the kernel itself does not recognize more than two network cards, at least lspci only sees 2 when I have 3 installed.

 

Is there any hope of supporting 3 (or more) NICs at any point, or should I be looking at separate hardware?

 

Cheers!

Intel 4 port nic. I use one with my pfsense vm.

Are you using that 4 port NIC w/hardware passthrough?

Yes, worked with opnsense as well.

On a side note, You should be able to see all cards in the system. Just bind them to the vfio, then assign to the vm. There is no limit as far as I know. The 4 port nic card is in a server with another mellanox 10gbe card as well as 2 onboard ports.

 

the 4 port card ids itself as : Intel Corporation 82576 Gigabit Network Connection (rev 01) and I believe it was on eBay as a Dell 4 port intel pro 1000 brand or something similar.

Makes me think the fact that the two are el-cheapo Realtek's may be why only one (Realtek) is listing in lspci, the other is an Intel e1000 82566DM. Maybe I will re-seat the card just in case. But I will keep an eye out for that 4-port.

 

Thanks!
