 ## Overhead memory of virtual machine
 Upon creating a virtual machine (VM), the VM controller seamlessly incorporates overhead resources into the VM's configuration. These additional resources intend to guarantee the consistent and uninterrupted functioning of the VM. It's important to note that configuring memory limits requires a higher memory reservation due to the inclusion of these overhead resources.
