What is CPU reservation in VMware?
A reservation specifies the guaranteed minimum allocation for a virtual machine. vCenter Server or ESXi allows you to power on a virtual machine only if there are enough unreserved resources to satisfy the reservation of the virtual machine.

Displays the minimum processing power in GHz available to a virtual machine. Assigning a CPU reservation ensures that even as other virtual machines on the same host consume shared processing power, there is still a certain minimum amount for this virtual machine.
What is a bad CPU ready time?
CPU ready time is dependent on the number of VMs on the host and their CPU loads. It is normal for a VM to average between 0–50 ms of CPU ready time; anything over 1000 ms is considered to lead to VM performance problems.

What is reserve all guest memory VMware?

What is acceptable CPU Ready?
It is normal for a guest to average between 0–50ms of CPU ready time, which is called the “guest heartbeat.” Anything over 300ms can lead to performance problems. On average, up to 300ms CPU Ready Time is acceptable, with a high water mark of 500ms.
Is vCPU the same as core?
Each vCPU is seen as a single physical CPU core by the VM’s operating system. If the host machine has multiple CPU cores at its disposal, then the vCPU is actually made up of a number of time slots across all of the available cores, thereby allowing multiple VMs to be hosted on a smaller number of physical cores.
