VS Disks

POST /virtual_machines 

Create a new VS


Request Parameters

memory* - amount of RAM assigned to the VS

cpus* - number of CPUs assigned to the VS

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

hostname* - set the host name for this VS

label* - user-friendly VS description

primary_disk_size* - set the disk space for this VS

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

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

primary_disk_type - set the storage type "HDD" or "SSD" for the primary disk

swap_disk_type - set the storage type "HDD" or "SSD" for the swap disk

primary_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. Optional parameter: if none set, the system sets port speed to unlimited

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")

required_ip_address_assignment* - set "1" if you want IP address to be assigned automatically after creation. Otherwise set "0"

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

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

hypervisor_id - the ID of a hypervisor where the VS will be built. Optional: if no hypervisor ID is specified, the VS will be built on the hypervisor 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 [ _ ]. You can use both lower- and uppercase letters

NOTE: It is not possible to set VS password when creating a Windows-based VMware virtual server without running a sysprep.

custom_variables - an array of custom variables with the following details:

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