DL360P Gen8 Hyper-V

[Rahamim]

Hi everyone,

We have 3 DL360P Gen8 with OS server 2016 and Hyper-V installed on them. Recently, we had an ISCSI network issue which forced us to check for drivers and firmwares ( I thought I installed everything but apparently not...) 2 of the servers went perfectly. The last one did install what was required but, After restarting the server I wasn't able to live migrate my VM's back to that server because of this error "Failed live migrate because "Virtual Machine Name" is using processor-specific features not supported on host "Node 1."".

Since it worked before the updates I don't know what to do. I don't know which update caused this...
The BIOS version is P71 and the processor is Intel XEON E5-2650 V2 on all servers.

I really need help here because it will be too much work to start shutting down servers and allowing to migrate to a different processor version.

Thanks in advance,

UPDATE: Apparently when deploying the firmware it changed some settings that mitigated the Spectre\Meltdown vulnerabilities. I'm running windows updates and will reinstall some drivers to check if that helps.

Apparently the HP updates that I ran changed settings that mtigated the spectre\meltdown vulnerability. I ran windows updates to patch to this month's updates and it repaired the problem. (The server itself was pathced last month)
