Questions[amd-v](server)

I'm currently faced with the problem of a Windows Server 2019 Standard Server hanging under heavy system load. The server in question is a host for windows docker containers that are used to compile and test .NET applications.

The server itself is a 2 socket system with two AMD EPYC 7451 processors and 128 GB of memory. The version of Windows used is Windows Server 2019 Version 1809 (Build 17763.1158).

The problem presents itself when the system is under heavy load, meaning around 90% load on both CPUs and like 90GB of memory usage, while at the same time creating and destroying docker containers. When the problem occurs the entire system suddenly stops, how ever while being connected to the physical VGA port of the server I noticed that the desktop was still working. I had the process explorer open at this time. The process list and all the graphs stopped dead, but the UI was still working. I was able to move the windows and switching the tabs in the system information of the process monitor was still working. How ever all functions that caused a new window to be opened instantly caused the process monitor ui to freeze up as well. The CTRL+ALT+DEL is not working anymore once the system is frozen, also I enabled CTRL+ALT+SCRLK to trigger a BSoD without success. How ever the mouse cursor is still working and switching num lock on the keyboard works as well. The event log shows no entries once the system is frozen and no errors right before. The last entry in the event log is usually a message from the Hyper-V VMSwitch, either creating or deleting a Hyper-V network. My guess was that the issue may be related to the system handles, because starting applications and creating windows did not seem to work anymore, but at the time of the system freezing there were only around 250k Handles active on the system.

To resolve the issue I already updated basically all the drivers for the hardware, I updated the firmware of all the hardware components that allow it and I updated the BIOS to the latest version, all without changing the situation. I also ran a stress test for the CPUs and memtest for the RAM. Both did not reveal any issues.

I'm running out of ideas what else to do or even what to look for at this point. Anyone here who had a similar issue or any advice what else I could try in order to resolve the issue?

I am not a hardware expert and am seeking help from them. I bought a Dell PowerEdge T105 server to run a Hyper-V setup for my Dev work. I did not want the OS from them as I already have the OS. So when I configured it on Dell's website I chose it without the OS and when I got it and tried to enable the Hyper-V role on Windows 2008 it gave me an error saying that I have to enable the Virtualization option in the BIOS. To my dismay that option was not there. I called Dell and they said that I would require another processor (AMD Opteron 1214 2.2 GHz Dual Core Processor for Dell PowerEdge T105 Server) instead of what I have. It's going to cost me $289.00 so I checked around locally and the processor was selling for $105, but it came in two options 65W and 103W. I have two questions - which processor should I buy for this? I could not find any information anywhere as to the wattage of the processor and if I put this new processor does the BIOS have to be updated or the Virtualization option would show up in the current BIOS version? I really appreciate any input on this as I sitting with this machine not able to use it for my purpose. Thanks.

I know it'd likely be more cost effective to buy a new system with AMD-V or Intel VT-x, but to prove it, I need to know if there are any 939 socket chips that feature AMD-V and if so what they are. This would allow one to run a windows server guest under Xen.

Update
This question will likely be of little use three years on, when you can't even reliably buy 393 socket chips. But I thought I'd mention that yes, the context was that I owned a socket 939 system and wanted to start running linux primarily with a Xen guest hosted Windows. For that I needed AMD-V, but it language on AMD's site was that all their chps support it, which it's clear from these answers that "ALL" wasn't including 939 chips.
