2.7.2Create M1.nano type

The default minimum size of the host requires MB of memory. For less than 4 GB of compute node memory in the environment, we recommend creating a host that requires only a size of "M1.nano". For testing purposes only, use the "M1.nano" version of the host to load the Cirros image

2.7.3.Adding security groups

a Add a rule to the default security group

OpenStack securitygroup rule Create--proto ICMP default

b allow access to secure Shell (SSH)

OpenStack securitygroup rule Create--proto TCP--dst-port default

2.7.4create an instance of the public network

On the control node, get Admin Credentials to obtain access to only the commands that an administrator can perform:

Sourcedemo-openstack

An instance specifies the approximate allocation of virtual machine resources, including processor, memory, and storage.
