    Having a VM use multiple bridge interfaces

    in VM Engine (KVM)

    Hello,

        I've been searching the forums and have had no luck, so I'm hoping someone might know what I'm missing. I have a new UnRaid server with two Intel GigE cards, each connected to a different VLAN. I have them both configured in the Web interface of UnRaid as bridging, br0 and br1 respectively. I have created an Ubuntu VM that I need two network interfaces; one from br0 and one from br1. Using the Ubuntu template br0 is the default and that is fine. My issue is adding br1 to the VM. I edited the VMs .xml and added a 2nd interface similar to br0, duplicating the configuration but changing only the slot number to an unused slot and changing the MAC address for the second NIC, so my configuration looks like this:

     

       <interface type='bridge'>
          <mac address='52:54:00:93:57:5f'/>
          <source bridge='br0'/>
          <model type='virtio'/>
          <address type='pci' domain='0x0000' bus='0x02' slot='0x01' function='0x0'/>
        </interface>
         <interface type='bridge'>
          <mac address='52:54:00:93:57:55'/>
          <source bridge='br1'/>
          <model type='virtio'/>
          <address type='pci' domain='0x0000' bus='0x02' slot='0x05' function='0x0'/>
        </interface>

     

    The second interface shows up in Ubuntu upon restart, but it remains in a disabled state and I can't assign it an IP address. The second VLAN contains a traffic intensive application that uses this VM and my router cannot handle the throughput, which is why I need the second interface on that VLAN. In frustration I tried passing through the entire NIC, but the IOMMU groupings won't allow that. Can anyone please point me in the right direction? Thank you very much in advance.

     

     

    Ok, this does work. As soon as I gave the interface an IP it came up. As the GUI didn't give me the option and I'm still coming up to speed on Linux, I didn't realize why it would stay disconnected. Hopefully this post will still help someone else, as I searched for a while and couldn't find the answer here, this Link on an Ubuntu forum showed me the answer, but the only step required was the editing of the .xml file as UnRaid had already taken care of the other steps. Interesting to see how the 2nd bridged interface becomes a drop down in the GUI.

     

    Having two bridge interfaces on Unraid server , BR0 and BR1,  will it be doing inter-bridge routing. Will the interface IPs BR0 and BR1 route be reachable to each other. I am asking because I want a similiar setup but I want inter-bridge communication controlled via external firewall.

    If you don't want any bonding, (3rd option down) Enable Bonding = No

    Array, VM + Docker services will need to be disabled if I remember right.

     

    If you want to pass it through to a VM, you will need to go over to Tools > System Devices and bind to VFIO (find your VM dedicated NIC and check the ticks next to it, press bind selected button)

    I disabled Bonding - changed option to No. After that I loose connection.

    Hi all, 

    I recently installed an additonal 2 PORT PCIe NIC card into my unraid server. It detected it fine, however it automatically puts all ports in Bonding ( see attached Unraid1 ). I cannot however change this config, If i remove bonding the server becomes unreachable. I have to restore network config from backup to get back in.

     

    I don't wan't bonding, i want NIC 1 dedicated to the box ( bridging ). I want to use other NICs for my other VM appliances.

     

    So far everything I tried has failed.. Can somebody help me in this.

     

    Thanks,

    Running ESXi on Unraid

    in VM Templates

    I used the above guide to install ESXi 6.7 and 7.0 up2a.  I had no issues with NIC's . However, I have a weired problem. I cannot copy anything to ESXi "datastores", either using webbrowser or SCP.  Forums attribute this behaviour to certificates, I have tried to resolve that too. However, this still does not work.

     

    No files can be copied to datastores..either during OVA deployment or direct upload to datastores.. Has anybody encountered this type of issue ? any help would be appreciated
