Nova help text for nova boot says that only mandatory arg for cli is
name but thats not true.

<name>
Boot a new server.
Positional arguments:
<name> Name for the new server.
Optional arguments:
--flavor <flavor> Name or ID of flavor (see 'nova flavor-list').
--image <image> Name or ID of image (see 'nova image-list').
--image-with <key=value> Image metadata property (see 'nova image-
show').
--boot-volume <volume_id> Volume ID to boot from.
--snapshot <snapshot_id> Snapshot ID to boot from (will create a
volume).
--min-count <number> Boot at least <number> servers (limited by
quota).
--max-count <number> Boot up to <number> servers (limited by
quota).
--meta <key=value> Record arbitrary key/value metadata to
/meta_data.json on the metadata server. Can be
specified multiple times.
--file <dst-path=src-path> Store arbitrary files from <src-path> locally
to <dst-path> on the new server. Limited by
the injected_files quota value.
--key-name <key-name> Key name of keypair that should be created
earlier with the command keypair-add.
--user-data <user-data> user data file to pass to be exposed by the
metadata server.
--availability-zone <availability-zone>
The availability zone for server placement.
--security-groups <security-groups>
Comma separated list of security group names.
--block-device-mapping <dev-name=mapping>
Block device mapping in the format <dev-
name>=<id>:<type>:<size(GB)>:<delete-on-
terminate>.
--block-device key1=value1[,key2=value2...]
Block device mapping with the keys: id=UUID
(image_id, snapshot_id or volume_id only if
using source image, snapshot or volume)
source=source type (image, snapshot, volume or
blank), dest=destination type of the block
device (volume or local), bus=device's bus
(e.g. uml, lxc, virtio, ...; if omitted,
hypervisor driver chooses a suitable default,
honoured only if device type is supplied)
type=device type (e.g. disk, cdrom, ...;
defaults to 'disk') device=name of the device
(e.g. vda, xda, ...; if omitted, hypervisor
driver chooses suitable device depending on
selected bus; note the libvirt driver always
uses default device names), size=size of the
block device in MB(for swap) and in GB(for
other formats) (if omitted, hypervisor driver
calculates size), format=device will be
formatted (e.g. swap, ntfs, ...; optional),
bootindex=integer used for ordering the boot
disks (for image backed instances it is equal
to 0, for others need to be specified) and
shutdown=shutdown behaviour (either preserve
or remove, for local destination set to
remove).
--swap <swap_size> Create and attach a local swap block device of
<swap_size> MB.
--ephemeral size=<size>[,format=<format>]
Create and attach a local ephemeral block
device of <size> GB and format it to <format>.
--hint <key=value> Send arbitrary key/value pairs to the
scheduler for custom use.
--nic <net-id=net-uuid,net-name=network-name,v4-fixed-ip=ip-addr,v6-fixed-ip=ip-addr,port-id=port-uuid>
Create a NIC on the server. Specify option
multiple times to create multiple NICs. net-
id: attach NIC to network with this UUID net-
name: attach NIC to network with this name
(either port-id or net-id or net-name must be
provided), v4-fixed-ip: IPv4 fixed address for
NIC (optional), v6-fixed-ip: IPv6 fixed
address for NIC (optional), port-id: attach
NIC to port with this UUID (either port-id or
net-id must be provided).
--config-drive <value> Enable config drive.
--poll Report the new server boot progress until it
completes.
--admin-pass <value> Admin password for the instance.
--access-ip-v4 <value> Alternative access IPv4 of the instance.
--access-ip-v6 <value> Alternative access IPv6 of the instance.
--description <description> Description for the server. (Supported by API
versions '2.19' - '2.latest')

Hence it looks like
