I have Four VM (VM1,VM2,VM3,VM4). now I am starting VM1 then VM2 and then others.
VM1 work properly but VM2 face high CPU utilization issue,
if I start first VM2 and then VM1. then issue come in VM1 not in VM2.

Hello @RahiPadariya-0447

Welcome to Microsoft Q&A Platform,

I would check if the Hyper-V host is running with the latest firmware and update drivers if needed
If there is any antivirus please remove it and check again
Using Task Manager you can check which are the apps/processes that consuming more CPU in the VMs

Please check the article below for reference:
https://docs.microsoft.com/en-us/archive/blogs/tvoellm/monitoring-hyper-v-performance

If this issue would need remote assistance & collection of logs for further assistance I would request you file a support ticket if you have a support plan.

I hope this helps!

As i Check server is running with latest firmware and drivers as available on server manufacturing site.

also this issue is not specific VM related, but issue observed in 2nd and 4th powered on VM. same i updated in my earlier comment.
please look in to and give some solution.
