#create(args = {}) ⇒ Object

Creates a virtual machine using provided paramters: :vm_name [String] - name of a vm :cpus [String] - number of cpus :memory_size [String] - amount of memory :memory_unit [String] - memory unit to use, default to ‘M’ :image [String] - name of a container disk :pvc [String] - name of a persistent volume claim :cloudinit [Hash] - number of items needed to configure cloud-init :networks - networks to which the vm should be connected, i.e:

[ { :name => 'default', :pod => {} } ,
  { :name => 'ovs-red', :multus => { :networkName => 'red'} }
]

:interfaces - network interfaces for the vm, correlated to

                   :networks section by network's name, i.e.:
[ { :name => 'default', :bridge => {} },
  { :name       => 'red',  # correlated to networks[networkName]
    :bridge     => {},
    :bootOrder  => 1,      # 1 to boot from network interface
    :macAddress => '12:34:56:AB:CD:EF' }
]

Parameters:

  • :image (String) —

    name of container disk.

  • :volumes (Array) —

    the volumes (Fog::Kubevirt::Compute::Volume) to be used by the VM

  • attributes (Hash) —

    containing details about vm about to be created.
