Table 34. Available Network Types for a vRealize Automation Network Profile
Network Type Description
External Existing physical or logical networks configured on the vSphere server. They are the external part of the NAT
and routed networks types. An external network profile can define a range of static IP addresses available on
the external network. An external network profile with a static IP range is a prerequisite for NAT and routed
networks.
NAT Created during provisioning. They are networks that use one set of IP addresses for external communication
and another set for internal communications. With one-to-one NAT networks, every virtual machine is assigned
an external IP address from the external network profile and an internal IP address from the NAT network
profile. With one-to-many NAT networks, all machines share a single IP address from the external network
profile for external communication. A NAT network profile defines local and external networks that use a
translation table for mutual communication.
Routed Created during provisioning. They represent a routable IP space divided across subnets that are linked
together using Distributed Logical Router (DLR). Every new routed network has the next available subnet
assigned to it and is associated with other routed networks that use the same network profile. The virtual
machines that are provisioned with routed networks that have the same routed network profile can
communicate with each other and the external network. A routed network profile defines a routable space and
available subnets. For more information about Distributed Logical Router, see NSX Administration Guide.
vRealize Automation uses vSphere DHCP to assign IP addresses to the machines it provisions,
regardless of which provisioning method is used. When provisioning virtual machines by cloning (with a
customization specified) or by using kickstart/autoYaST provisioning, the requesting machine owner can
assign static IP addresses from a predetermined range.
Assigning a Static IP Address Range
You can assign static IP addresses from a predefined range to virtual machines that are provisioned by
cloning, by using Linux kickstart/autoYaST, or to cloud machines that are provisioned in OpenStack by
using kickstart.
By default, vRealize Automation uses Dynamic Host Configuration Protocol (DHCP) to assign IP
addresses to provisioned machines.
An administrator can create network profiles to define a range of static IP addresses that you can assign
to machines. You can assign network profiles to specific network paths on a reservation. Any cloud
machine or virtual machine that is provisioned by cloning or by kickstart/autoYaST that is attached to a
network path with an associated network profile is provisioned with an assigned static IP address. For
provisioning with a static IP address assignment, you must use a customization specification.
You can assign a network profile to vSphere machine component in a blueprint by adding an existing, on-
demand NAT, or on-demand routed network component to the design canvas and then selecting a
network profile to which to connect the vSphere machine component. You can also assign network
profiles to blueprints by using the custom property VirtualMachine.NetworkN.ProfileName, where N
is the network identifier.
