[[6.12.3] VM Getting Multiple MAC Addresses]

@limetech  would you happen to know if that is possible?

[[6.12.3] VM Getting Multiple MAC Addresses]

Okay thank you so much. There has to be a way to tell Unraid treat it as one NIC and pass it to the VM as one and not have multiple dns records on the network. 

Again, thank you for all your help. @limetech would you happen to know if that is possible?

I haven't those multiple port / controller NIC, it have some different behavior if compare to general NIC, but this also work with Unraid.

Mutliple MAC on a switch port not a problem. 

So, this is normal and there is no way to tell Unraid to treat it as one nic for the VM so the switch does not think is multiple devices on the same port?

[[6.12.3] VM Getting Multiple MAC Addresses]

I will leave it like this for a while to see if it falls off. However, how can we make this work with the pcie two port nic card? That port I have a different used for it.

But why 00:07:43 Chelsio Communications instead AQC107 ?

 

Okay so I just noticed something. That NIC is built to the motherboard and is the one I was using for my 10gigabit folder share.

 

However, I do see that is getting a 10.10.50.4 with the name of the server. Also, now on the Windows OS it has assigned 10.10.50.6.

Pls note I never touch your router / switch part, because according previous post, the VM ( br2 ) was connect to port #7. Pls understand the test are use same setting, just only change the eth2 ( br2 ) to use AQC107 NIC.

I apologize for the confusion. Everything is still the same other than the Interface Rules your advice to change. eth2 (br2) is connected to Port #7 still.

Does eth2 connect to port #7, btw no problem on network setting.

Eth2 is connected to port #7. 

 

[[6.12.3] VM Getting Multiple MAC Addresses]

Now the VM is not getting an IP address. See below. @Vr2Io

Yes

Okay I just did that. Ill let you know if it stops reporting that there are three devices. Dude thank you so much for your help. Fingers crossed.

[[6.12.3] VM Getting Multiple MAC Addresses]

Do you mean set this Interface eht2: to Atlantic on the Interface rules? @Vr2Io

 

[[6.12.3] VM Getting Multiple MAC Addresses]

Yes, if you insist one MAC and IP ( VM )  in standalone switch port i.e. #7, set eth2 ( br2 ) to use AQC107, VM use br2.

The VM is set to BR2 and it saying there are three MAC Addresses and two with different IP and the other one does not have an IP Address. See screenshot below. Back to square one.

Pls found I have edit the post.

So you want me to place it back to BR2 and see if the multiple MAC address happens and multiple IPs?

[[6.12.3] VM Getting Multiple MAC Addresses]

For ping issue, Windows firewall default were disable , pls check does this is the case.

 

For still found two different MAC, it show 70:85:C2 is Asrock physical NIC ( eth0 ), so you have add it to VM actually. Pls check VM XML.

 

The firewall issue is the windows os. But the issue with multiple MAC on the same Port on the switch still exist. I don’t know what you are wanting me to try.

Understand that, the test is to identify the problem source. Virtual NIC won't change MAC address self, but I notice you have some call trace relate GPU, this may cause problem too.

Okay. So I went to the VM template and switched it to BR0 and it got an IP of 10.10.1.158 but I cannot ping it from my desktop which is on the same subnet.

 

So technically the problem is the same just that the server has 10.10.1.43 and the VM has 10.10.1.158 and both are showing on Port # 6. It also has two different MAC Addresses.

Thank you so much for your help @Vr2Io.

I can also try to bind together the chelsio ethernet card and pass it through, but there are way too many controllers, and I don't know which ones to bind. It is a 2 nic card and common sense would be 2 ethernet controller per nic but I tried that, and it didn't work. See image below.

Try swap eth1 & eth2, so, Aquantia Corp. AQC107 be eth2 ( br2 ), of course, you need connect it to switch port #7 too.

 

Or more simple, change VM NIC using br0 ( then IP will be 10.10.1.43/24 ) and check back same problem happen or not.

 

Why try not use Chelsio NIC, because it have multiple ethernet controller.

One of them is the Unraid IP address and Docker containers. I want that VM on a different subnet so I can controlled the traffic on that VM. I don’t want to place it on the same IP as Unraid because then I won’t have control over that VM traffic. I hope that makes sense.

@bonienl do you have any idea of what the issue could be?

I have not seen anythink at the point have you tried new 6.12.4 rcs as may help @bonienl any other suggestions

Hello @bonienl and @SimonF,

 

I just updated to 6.12.4 stable version and issue still persist. I downloaded new 6.12.4 diagnostics file. I also grabbed a screenshot of the VM network setting. On my Unifi network, it shows up as 3 different machines. When I sign in into the Windows VM it says the IP Address is 10.10.50.4 and when you ping the VM it doesn't respond. But when you ping 10.10.50.3 which is the one that the Unifi controller says is up, it responds.

 

 

Also, on this screenshot you can see that it says three machines, but only two got IP addresses, however, the connection switch port #7 is correct but no IP address.

@SimonF have you had the chance to review the logs and the answers to your questions?

[[6.12.3] VM Getting Multiple MAC Addresses]

My network looks like this:

 

Modem -> UDM Pro -> USW Enterprise 24Port -> Unifi 8 Port Switch -> Unraid server. 

My unraid server motherboard NIC is connected to a port for webui and docker containers. I then have a separate 2 port NIC on a PCIE port on the motherboard. The other NIC on the mother board is connected straight to my personal computer. 

 

I hope this is what you are wanting. If not let me know. 
 

I have three VM but only one is used all the time. The others are just there for testing purposes. I believe two of the bridges should be using DHCP. 

[[6.12.3] VM Getting Multiple MAC Addresses]

@limetech are you able to review or guide me to someone that can help me with this please? I appreciate anything on this issue.

Looks like it, you can post the diagnostics to see if there's something visible there.

Hey @JorgeB were yo able to review the logs and see anything that stood out?

[[6.12.3] VM Getting Multiple MAC Addresses]

Good morning @JorgeB, here is the diagnostics. I also changed the network model from E1000 to virtio and my unifi still reports multiple Mac Address. Thank you for your help!
