Note that the bond has a MAC address that is the same as both member interfaces. Note that the bond and it’s member interfaces have the same MAC address that does not come from the Hyper-V host pool Well, let’s look at the nic interfaces and the bond. I did check the option “Enable this network adapter to be part of a team in the guest operating system” on both member vNICs. I have created a bond using eth0 and eth1, and we should get an IP address from DHCP. In Ubuntu, we use netplan to configure our networking and in the image below you can see a sample configuration. So, what could be the cause? Configuring an interface bond in a Ubuntu Hyper-V guest But, much to my surprise, I did not get an IP address from my DHCP server on my Ubuntu 20.04 guest bond.

For example, recently, on Ubuntu 20.04, I went through my typical motions to get in guest NIC teaming or bonding in Linux speak. But sometimes, I need to have a NIC team inside a Linux guest virtual machine.

Do test failover to make sure you got it right? As you can see in the image below, both my LAN NIC and the NIC get an address from the DHCP server. There is nothing more you need to make it work perfectly in a Windows guest VM. Enable NIC teaming o the vNIC that are going to be team membersthe Hyper-V settings Otherwise, you will see a “The virtual switch lacks external connectivity” error on the remaining when failing over and packet loss. The big caveat here is that each member must reside on a different external vSwitch for failover to work correctly. NIC teaming inside a Hyper-V Guestįor each vNIC member of the NIC team in the guest, you must put a checkmark to “enable this network adapter to be part of a team in the guest operating system” there is nothing more to it. That is the case for Windows Server 2012 and later. Als long as that OS supports native teaming. Hyper-V has a setting for your vNICs, enabling them to be functional members of a NIC team in a Windows guest OS. However, you might have a valid reason to use NIC teaming for lab work, testing, documenting configurations, teaching, etc. In-guest teaming is rarely used for production workloads, that is, bar some exceptions with SR-IOV, but that is another discussion.
