Virtual Switch on Hyper-V Server (Core) fails

Question

I've installed Hyper-V Server on a Dell R630. Updated drivers and ran updates, restarted. Everything seems OK, but I cannot create a Virtual Switch because of a very strange error.

Answer 1

I'd check that the chipset has been installed. The chipset allows an operating system to find and use devices integrated into the mother board.

Answer 2

Hi,
Please tell me which type of virtual switch did you create, external or internal?
Since you are using Hyper-V Server Core and create the virtual switch by cmdlet, please show me the screenshot to help check.
Or you can use Remote Server Administration Tools (RSAT) to remotely manage Hyper-V hosts and VMs from another computer, and try to create the virtual switch.
If the above doesn't work, please check if there’s any event ID in Applications and service logs>Microsoft>windows> Hyper-V-VmSwitch/Hyper-V VMMS, if yes, please provide the detailed error information.
Thanks for your time!
Best Regards,
Mico Mi

Answer 3

This server has an add-in NIC card, a 4 port Intel, which is an exact duplicate of the same card in a PE R730xd. I decided to pull out that card from the R630 and I am now able to create a Virtual Switch (External). Mico Mi, if I was creating an internal, it would ignore the need for a NIC port. I am using RSAT, and I suspect that because there was so many NIC ports available, powershell was maxing out it's characters on a single line. I have now created two virtual switches that work fine. I need to put the Intel card back in and see if it still works or not since now two of the NIC ports are in use, in addition to the physical server's nic port.
