Hi,
We have buy a new AMD (EPYC 7413 24-Core Processor + 512 Go de RAM and Full SSD) server (we working with intel only before) but we want to try AMD...
We have installed Windows Server 2022 on this server (all other Hyper-V (x4) server are on Server 2016)
Yeterday, I have to rollback my migration because after move 10 vm hyper-v on this new server, it had become unstable :
Can’t control VM at all (if they are online, I can’t stop it for example, and some of them who are stop can’t be start.. I have status stuck on « starting… »), it’s like the vmms it’s completely stuck (I tried to restart the process (vmms service) many times, but doesn’t work)...
If I restart the whole server the process works again I can start VM fine but after few minutes it’s broken again… I'm loosing the control of the VMs.
I can't open settings parameters of VM for example.. Need to restart whole server again to retake the control..
At the first time, I was thinking that a VM in the lot crashed Hyper-V (I had the problem once on another server, but It was not exactly the same symptoms, I was not able to launch console for example in this case...).
It was a VM with a network card who cause the issue, and I had to delete the card and add a new one.. I'm wondering if it's not the case again... I have found a similair problem on a website, the user had a BSOD caused by linux VM on a AMD server.. No BSOD in my case however.
In the problematic server, I have found warning info in the log many times :
VMs Utilization Plan Vport QueuePairs adjusted from the request number 16 to real number 4.
Reason:
The number of requests exceeds the maximum number of QP per VPort supported by the physical network.
Event ID => 280
I found nothing on the web about this event, do you what is it ? The time log seems to fit the problem.
I have planned to reinstall the whole server in Windows server 2019 and reinstall hyper-V role to know if it's caused by a sort of incompatibility between OS and drivers ? I didn't find drivers for Windows server 2022 and I'm wondering if it can be the problem.
If you have any idea...
Thanks again !!
