+Attempts to provision VMs for guest clusters are blocked when the resource quotas are reached. Rancher responds by creating a new VM in a loop, in which each failed attempt to create a VM is immediately followed by another creation attempt. This results in a transient error state in the cluster that is not recorded as the VM is recreated.

 ## 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.
