acceleration_allowed - true if acceleration is enabled for the VS; otherwise false

memory* - amount of RAM assigned to the VS, MB

cpus* - number of CPUs assigned to the VS. For KVM compute resources, this parameter sets CPU sockets by default, unless CPU topology is enabled.

cpu_shares* - required parameter. For KVM compute resource the CPU priority value is always 100. For XEN, set a custom value. The default value for XEN is 1

cpu_units - the amount of CPU units per core if the CPU priority is replaced with CPU units in user bucket.

cpu_sockets - the amount of CPU sockets. This parameter can be set for KVM compute resources only by those users who have Enable CPU topology permission granted.

hostname* - set the host name for this VS

domain - specify the domain for this VS. The default value is localdomain. You can edit the default value for domain in /onapp/interface/config/on_app.yml. This parameter is not applicable to Windows virtual servers. 

instance_package_id - ID of the instance package that will be used to build the VS

label* - user-friendly VS description

location_id - set the ID of the location where the VS should be created

primary_disk_size* - set the disk space for this VS, GB

swap_disk_size* - set swap space. There is no swap disk for Windows-based VSs

primary_disk_min_iops - minimum number of  IO operations per second for primary disk (this is a SolidFire related parameter)

swap_disk_min_iops - minimum number of  IO operations per second for swap disk (this is a SolidFire related parameter)

type_of_format - type of filesystem - ext4. For Linux templates, you can choose ext4 file system instead of the ext3 default one

data_store_group_primary_id - set the ID of the data store zone to which this primary disk is allocated

data_store_group_swap_id - set the ID of the data store zone to which this swap disk is allocated

network_id - the ID of the primary network. Optional parameter that can be used only if it is assigned to the network zone.

primary_network_group_id - the ID of the primary network group. Optional parameter

required_automatic_backup - set 1 if you need automatic backups

rate_limit - set max port speed in Mbps or set 0 to get maximum port speed allowed by your bucket. If this parameter is omitted or sent without value, the default port speed will be configured for the VS. The default port speed depends on the maximum port speed set in your bucket and the Max network interface port speed parameter at Control PanelSettings >Configuration. The system identifies which of the two values (in the bucket or in the configuration) is lower and sets it as the default port speed during VS creation.

required_virtual_machine_build * - set 1 to build VS automatically

required_virtual_machine_startup - set 1 to start up the VS automatically, otherwise set 0 (default state is "1")

time_zone - the time zone set for the VS. This parameter is applicable only to Windows virtual servers.

Currently, the time zone is set at the Compute resource side only. Therefore, users need to set the target time zone inside a Windows VS manually. Setting the correct time zone at the Compute resource side helps to keep the correct time inside a VS after starting it if time synchronization is not completed for some reason.

selected_ip_address - an IP address to assign to this VS

admin_note - enter a brief comment for the VS. Optional parameter

note - a brief comment a user can add to a VS

template_id * - the ID of a template from which a VS should be built

Make sure that a template is located on a backup server attached to the compute resource on which you wish to build the VS, otherwise, the creation of the VS will fail.

licensing_server_id * - the ID of a template group where the KMS server details are indicated and to which the template belongs (either directly or through the child group). This parameter is for Windows virtual machines with KMS licensing type only

licensing_type * - the type of a license: makkm, or user own license. This parameter is required for Windows virtual machines only

licensing_key * - the key of a license, required if you have selected own licensing type, and not required for MAK and KMS licensing types

hypervisor_group_id - the ID of the compute zone in which the VS will be created. Optional: if no compute zone is set, the VS will be built in any available compute zone

hypervisor_id - the ID of a compute resource where the VS will be built. Optional: if no compute resource ID is specified, the VS will be built on the compute resource with the least available RAM (but sufficient RAM for the VS)

initial_root_password - the root password for a VS. Optional, if none specified, the system will provide a random password. It can consist of 6-32 characters, letters [A-Za-z], digits [0-9], dash [ - ] and lower dash [ _ ], and the following special characters: ~ ! @ # $ * _ - + = ` \\ { } [ ] : ; ' , . ? /. You can use both lower- and uppercase letters.

The following characters are not allowed for Windows-based virtual servers:

  • percent sign [%]
  • double quotation marks [“]
  • brackets [<,>]
  • vertical bar [|]
  • caret [^]
  • ampersand [&]
  • parentheses [(,)]

initial_root_password_encryption_key - specify the password encryption passphrase

recipe_joins_attributes - an array of recipes to run on the virtual server provisioning with the details:

  • sequence_number - must be unique
    • recipe_id - the ID of the recipe 

custom_recipe_variables_attributes - an array of custom variables with the details. 

  • enabled - true, if the variable is enabled, otherwise false
  • name - variable name
  • value - variable value script

service_addon_ids - an array of service add-on IDs, which you want to add to VS
