We have been using Virtualization Manager for a while and we realized that the Memory and CPU utilization which it is displaying for each VM is not matching the actual/real utilization.
We checked and verified this issue with multiple VM's (Windows, Linux etc.) and everywhere the results are similar.
Any idea why this is happening?
Is Virtualization Manager showing different than vCenter or the Guest OS?
Virtualization Manager gets it data from vCenter or the ESX servers in your environment, so we are looking at how the VM's are loading your virtual infrastructure, which can be different than how the OS on the VM is reporting its usage. This is the true load of the VM, and how your VM's are managed (vmotion, storage vmotion) by VMware.
Does that help?
