A Windows 2000 server, converted from physical to virtual and hosted by an ESXi 5.0 host member of a vSphere 5.0 infrastructure, reports CPU usage up to 95% during peak hours, while during the rest of the day the CPU usage is very limited.
The guest is configured with 2 (vitrtual) CPU and the CPU priority is High.
What is the best strategy to mitigate che problem without impacting on the hosted, legacy applications and minimizing the impact on other guest VMs?
- Add vCPU or cores?
- Reserve CPU resources?
- What else?
Happy new year!
