Performance metrics within a Virtual Machine's Guest OS are different (higher or lower) than the same metrics reported by Veeam ONE.
Virtual machine’s guest OS is unaware of hypervisor resource overheads. This occurs because the guest OS is only permitted to view a certain portion of all available resources as determined by hypervisor’s scheduler.
Resource overheads often change based on workloads.
There may be a time difference between performance data displayed at the guest and hypervisor level. Additionally, the time intervals at which performance data is recorded and displayed may differ between the guest OS’s resource monitor and the hypervisor’s resource monitor.
Because a virtual machine’s guest OS is unaware of its hypervisor’s resource distributions, it is therefore unaware of being “de-scheduled” while idle.
