Hello all
Trying to install Hyper V machines to win server 2012
ANd i activated the Hyper V role and assigned the network card of the server to be used a virtual card for the virtual machines.
BUt when i add the machines i get the not connected option for the machines.
And when accessing the switch manager i get the error
an error occurred while trying to retrieve a list of virtual switches.
Please help, stuck on this for a week now. Tried almost all the tricks found on the net.

"Tried almost all the tricks found on the net."
This is not very definitive, so we have to ask. Did you try removing and re-installing the Hyper-V option on the host? Is your system a supported system? See www.windowsservercatalog.com and search for your system for support of Windows Server 2012.
"i activated the Hyper V role and assigned the network card of the server to be used a virtual card for the virtual machines."
I understand that you are new to Hyper-V and may not know all the proper terminology. One does not assign a physical network card of the host "to be used a virtual card for the virtual machines". One creates a virtual switch on a physical NIC, and virtual NICs assigned to that virtual switch can then be created for the virtual machines. Could you give a synopsis of the steps you followed to create the virtual switch and assign the NIC to the VM?

Add roles and features > Hyper V> extra features> assign network> finish >restart
Yes tried removing and reinstalling an all
Same steps followed in a win 2016 server and all works fine without any issues.
Nothing different from my part and it works in 2016 http://prntscr.com/lr2uup
For some reason the DC wont allow me to install anything other than 2012 on the server which is facing the issue.

Question remains - is this system a supported system for Windows Server 2012?

Not sure how can i know if i ts supported or not. I am not understanding what to do in the https://www.windowsservercatalog.com/.
The server is use is a Intel Xeon E3-1245v2 4c / 8t 3.4GHz 32GB DDR3 1333 MHz SoftRaid 2x480GB SSD

www.windowsservercatalog.com is a repository of systems and components that have been validated by the hardware vendors to run specific versions of the Windows Server operating system. If a system or a component does not exist for the version of the operating system you are running, you are running an unsupported piece of hardware. That does not mean it will not work, but it does mean that the hardware vendor has not validated it for that version of the operating system. This could be a marketing decision by the vendor, i.e. they no longer want to support an older component/system on a newer release, or they have determined there are problems with that component/system and they do not want to invest in building a fix that would overcome the issue.
The only component you have listed is the Intel processor. The E3 is an older processor, and it looks like you have an early version (v2) of that processor. current version of that processor is v6 (https://www.intel.com/content/www/us/en/products/processors/xeon/e3-processors/e3-1245-v6.html). But since you are trying to install an older version of the OS, you might be OK.
Since you are listing components, is this a system you built yourself? If it is a vendor's system, you simply need to search for the vendor's system on Windows Server catalog web site. If the vendor supports Windows Server on their system, it will list which versions of the OS are supported.
If it is not found, then the vendor does not support it. If it is a system which you built, then you need to ensure all the individual components in the system are supported by the individual hardware vendors. Building systems leaves the responsibility for integration testing up to the system builder.
Self-built systems that are built from verified components should work fine. But there may be issues with integration. The biggest issue with self-built systems is the requirement for self-support. When an error occurs, about the only recourse is to contact the vendor of the failing component to see if they have any suggestions.
What you should do is make sure that all firmware and drivers for all components is at the level recommended by the vendor for the operating system version you are running.

Its a so you start server.
I have two of them same config as above. One runs on win 2016 (has no issues with the virtual switch)
Second one is on win 2012 which faces this issue.
I have installed 2012 on same spec servers in the past, but now :(
Have asked the SYS support, but they take 5-6 days to make one reply.

Okay, I had never heard of that organization before. But it does mean that you have to contact them with your problem. They need to be able to tell you that the hardware they are providing you supports Hyper-V on Windows Server 2012.

Hi,
OK, I'm wondering of reviewing and confirming the current situation of this issue.
1) You reinstalled the Hyper-V role on your OS?
2) Your OS version is windows server 2012?
3) Did you check your OS subversion by typing "winver" in the RUN? Would you mind posting the subversion here? And did you check the 2012 update history and have it up to date?
4) You've checked your hardware is supported for windows server 2012?
5) Now current error is still the same as the former error?
6）We need to also check if there's any other errors regarding Hyper-V in the event viewer. We could refer to the following link,
Looking at the Hyper-V Event Log (January 2018 edition)
Highly appreciate your effort and time, if you have any question or concern, please feel free to let me know.
Best regards,
Michael

1) You reinstalled the Hyper-V role on your OS?
Yes a dozen times, even tried reinstalling the OS (2012)
2) Your OS version is windows server 2012?
Yes
3) Did you check your OS subversion by typing "winver" in the RUN? Would you mind posting the subversion here? And did you check the 2012 update history and have it up to date?
Version 6.2 (build 9200) Datacenter
Yes , all updates are installed. Checked once again right now and no updates pending
4) You've checked your hardware is supported for windows server 2012?
NO sure how to do that.
This is the server i have
https://www.soyoustart.com/ie/offers/1801sys47.xml
5) Now current error is still the same as the former error?
Yes , same error
6）We need to also check if there's any other errors regarding Hyper-V in the event viewer. We could refer to the following link,
Hyper-V Setup: Post-install configuration task could not complete because one or more Hyper-V components are not available.
'Network Virtualization Service Provider' driver required by the Virtual Machine Management service is not installed or is disabled. Check your settings or try reinstalling the Hyper-V role.
The virtualization infrastructure driver (VID) is not running.
These are the 3 errors in the event viewer
Thanks for the help and time you are taking

The information provided there is insufficient for determining if the platform is supported. It basically provides a processor model. Yes, the processor is a supported model, but it does not mention any of the other necessary components, for example the NICs. Nor does it specify firmware and driver versions. Your problem is with a function related to the physical NIC, and there is no information about the NIC in what you have provide.
This is why I keep saying that you need to contact your service provider and have them certify that the platform they are providing is a certified platform. It looks like they are using self-built servers. In which case, it is up to them to support any hardware integration issues. They need to ensure all components are at the OEM component firmware/driver level recommended by the OEM vendor for use with 2012. Then they need to certify the system to ensure all the parts work together.

Hi,
How are things going on?
Yes, we need to assure your hardware is supported for virtualization and Hyper-V deployment as Tim said.
Furthermore, please check the following thread which is in a similar situation like yours. Hope this helps.

Hi,
Any movement on this??
Question: WHERE does this list of virtual switches exist?? It's corrupt in some way.
