VM on VF can not talk to VM on Bridged network


Recommended Posts

I follow the how-to in the forum and using SR-IOV to create some VFs , and create a VM using the VF, but the VM on VF cannot talked to the VM on br0 network

1. VM1 is assigned a direct VF, on network 192.168.2.0/24

2, VM2 is usinn the urnaid default br0  to 192.168.2.0/24

3. VM1 can access unraid host and internet

4. vm2 can access urnaid host and internet

5. other PC on same network can acess unraid host, vm1, vm2

6. But VM1 and VM2 cannot take to each others

 

google search can find some post like below:

https://community.intel.com/t5/Ethernet-Products/SR-IOV-on-82576-on-VM-on-VF-can-not-talk-to-VM-on-Bridged/td-p/196387

 

the solution is to use "bridge fdb add" command to add VF mac addresses and eth0 mac address to bridge forwarding

 

but the issue here is unraid don't have the "bridge" command included,  is there any other sulution for this issue?

Guys, when I using the VF on VM,  it cannot talk to the VM on br0,   do you guys has this issue?

  

I can't reproduce this issue with 82599 or ConnectX-2 SR-IOV.

 

Is your 82576 a dual-interface adapter?  If so, you could potentially get around this by using SR-IOV on the second interface and br0/VMs on the first interface only?
