Create a VM Class in
vSphere Supervisor

You can use the
vSphere Automation
 Kubernetes
REST
APIs to create custom VM classes to be used for VM deployment in
vSphere Supervisor
.

A VM class specifies the CPU, memory, and resource reservations for a VM.
vSphere Supervisor
 offers several preconfigured VM classes which you can use as is, edit, or delete. You can also create a custom VM class in your
vCenter Server
 instance and it will be available to all
Supervisors
 and the namespaces created in these clusters. Note that even though a VM class is available to all namespaces, a DevOps user can only use the VM classes associated with the namespaces that he/she can access.
  1. Create the specification of the VM class object by defining the following options.
    Option
    Description
    id
    The identifier of the VM class must follow these DNS requirements:
    • A unique name in the current
      vCenter Server
       instance.
    • An alphanumeric name with maximum 63 characters.
    • No uppercase letters of spaces.
    • A dash can be used anywhere except as a first or last character.
    Note that after a VM class is created, you cannot edit its ID.
    cpu_count
    The number of virtual CPUs (vCPUs) configured for a VM that are deployed with this VM class.
    memory_MB
    The memory in MB configured for a VM that are deployed with this VM class. The value must be between 4 MB and 24 TB and a multiple of 4.
    description
    Optional. The description of the VM class.
    cpu_reservation
    Optional. The percentage of total available CPU resources reserved for the VM deployed with the VM class. The percentage you specify with this attribute is multiplied by the minimum CPU available among all cluster nodes to get the CPU resources guaranteed by vSphere for a VM. The resulting value is in MHz.
    memory_reservation
    Optional. The percentage of available memory that is reserved for a VM deployed with this VM class. The value can be from 0 through 100%.
  2. Create the VM class object.
    Use the
    POST https://
    <vcenter_ip_address_or_fqdn>
    /api/vcenter/namespace-management/virtual-machine-classes
     HTTP request and pass the created VM class specification in the request body.
After you create the custom VM class, you can edit its parameters or delete it from your environment. See Editing or Removing a VM Class from Your Environment.
You can make your VM class available to DevOps engineers by associating it with a namespace. See Associating a VM Class with a vSphere Namespace.
