Hello,
I am working with a client that has a new Windows Server 2016 box running Hyper-V. We migrated a couple of VM's (one 2008R2 and one 2012) to it and I had difficulty getting them to communicate on the network. The host has 4 NIC's and I created four virtual switches. After troubleshooting for some time I managed to get one VM communicating on the network by disabling VMQ on the host's NICs. However, the other VM still had no connectivity. I had it on the same virtual switch as the one that did have connectivity to rule out any issues with the other NICs or upstream connectivity/VLAN issues etc. After spending a certain amount of time trying to figure out why the second VM had no connectivity, I advised the client to open a case with Microsoft.
He opened the case and it was worked on yesterday. The client reports that they moved the problem VM to another virtual switch and it gained connectivity. I had it on its own switch at one point and it wasn't communicating so I don't know why it suddenly worked.
However, the crux of my post is this: the MS engineer the client was working with told him that you could have ONE AND ONLY ONE virtual machine per virtual switch. I immediately called B.S. on this with the client but said I'd research to see if that changed in 2016, but I seriously doubted it did. I researched and it appears I'm correct. It would be ridiculous to think you had to have one physical NIC per virtual machine on a 2016 host (though it would be great marketing for a move to VMware).
Can someone verify that this Microsoft engineer is completely wrong?
Thank you,
Toni
