- vpci - (optional) virtual vPCI address to assign at the VM. Can be ignored depending on VIM capabilities
- model: (optional and only have sense for type==virtual) interface model: virtio, e1000, ...
- mac_address: (optional) mac address to assign to this interface
- type: (mandatory) can be one of:
- virtual, in this case always connected to a network of type 'net_type=bridge'
- 'PCI-PASSTHROUGH' or 'PF' (passthrough): depending on VIM capabilities it can be connected to a data/ptp network ot it
- can created unconnected
- 'SR-IOV' or 'VF' (SRIOV with VLAN tag): same as PF for network connectivity.
- VFnotShared - (SRIOV without VLAN tag) same as PF for network connectivity. VF where no other VFs
- are allocated on the same physical NIC
- bw': (optional) only for PF/VF/VFnotShared. Minimal Bandwidth required for the interface in GBPS
- port_security': (optional) If False it must avoid any traffic filtering at this interface. If missing or True, it must apply the default VIM behaviour
- vim_id': must be filled/added by this method with the VIM identifier generated by the VIM for this interface. 'net_list' is modified
- elastic_ip - True/False to define if an elastic_ip is required
- cloud_config': (optional) dictionary with:
- key-pairs': (optional) list of strings with the public key to be inserted to the default user
- users': (optional) list of users to be inserted, each item is a dict with:
- name': (mandatory) user name,
- key-pairs': (optional) list of strings with the public key to be inserted to the user
- user-data': (optional) string is a text script to be passed directly to cloud-init
- config-files': (optional). List of files to be transferred. Each item is a dict with:
- dest': (mandatory) string with the destination absolute path
- encoding': (optional, by default text). Can be one of:
- b64', 'base64', 'gz', 'gz+b64', 'gz+base64', 'gzip+b64', 'gzip+base64'
- content' (mandatory): string with the content of the file
- permissions': (optional) string with file permissions, typically octal notation '0644'
- owner: (optional) file owner, string with the format 'owner:group'
- boot-data-drive: boolean to indicate if user-data must be passed using a boot drive (hard disk)
- security-groups:
- subnet_id
- security_group_id
- disk_list': (optional) list with additional disks to the VM. Each item is a dict with:
- image_id': (optional). VIM id of an existing image. If not provided an empty disk must be mounted
- size': (mandatory) string with the size of the disk in GB
- Returns a tuple with the instance identifier and created_items or raises an exception on error
- created_items can be None or a dictionary where this method can include key-values that will be passed to
- the method delete_vminstance and action_vminstance. Can be used to store created ports, volumes, etc.
- Format is vimconnector dependent, but do not use nested dictionaries and a value of None should be the same
- as not present.
