I have an issue with a Windows 2012 Standard server running Hyper-V in a Cluster that will only allow one VM use networking. The server is a Dell R710 with 4 x Broadcom network ports and 4 x Intel network ports. I have the 4 Intel ports used for SAN storage, and the Broadcom’s for Hyper-V. I have tried with Windows 2012 NIC teaming, Broadcom teaming, and also without teaming on a single network interface. I currently have two VM’s, both are attached to the same External Switch, and both see the virtual nic, but only one gets network/internet connectivity.
I have verified the Bios and all firmware is up to date, and all 2012 updates are in place. I’ve deleted the virtial switch and re-created, removed connectivity to System Center 2012… aside from rebuilding this server, I do not know what to try next.
As far as I can see I am not receiving any errors. Any assistance would be greatly appreciated. I’ve built a few 2012 Hyper-V server, clustered and connected to System Center, and have not seen this issues before.
