Hi,
I'm new in this vmware world. We are using vSphere Client 4
We have a host machine (2 chips with 6 CPUs (2.4 mhz) and hyperthreading=>24 rcpu ) with 2 vm running asterisk where CentOS is th OS.
One of the VM is showing high CPU usage, it was configured with 4 vCPUs and 9575 MHz, memory 7396 MB. I tried to increase the amount of vCPUs but I read this warning: "changing the number of CPUs after OS installed may make vm unstable".
So what I did was:
adding more shares in CPU (from 4000 to 6000) and adding reservation: 9572 Mhz.
After that I saw a change in the perfomance graph, (I attached the figure).
Are that actions solve my problems? Do I have to add more vCPUs anyway?
If I add more vCPUs will I have a problem with my VM?
Regards,
Rafael
