When vRealize Automation provisions machines with NAT or routed networking, it provisions a routed
gateway as the network router. The Edge or routed gateway is a management machine that consumes
compute resources. It also manages the network communications for the provisioned machine
components. The reservation used to provision the Edge or routed gateway determines the external
network used for NAT and routed network profiles. It also determines the reservation Edge or routed
gateway used to configure routed networks. The reservation routed gateway links routed networks
together with entries in the routing table.
You can specify an Edge or routed gateway reservation policy to identify which reservations to use when
provisioning the machines using the Edge or routed gateway. By default, vRealize Automation uses the
same reservations for the routed gateway and the machine components.
You select one or more security groups in the reservation to enforce baseline security policy for all
component machines provisioned with that reservation in vRealize Automation. Every provisioned
machine is added to these specified security groups.
Successful provisioning requires the transport zone of the reservation to match the transport zone of a
machine blueprint when that blueprint defines machine networks. Similarly, provisioning a machine's
routed gateway requires that the transport zone defined in the reservation matches the transport zone
defined for the blueprint.
When you select an Edge or routed gateway and network profile on a reservation when configuring
routed networks, select the network path to be used in linking routed networks together and assign it the
external network profile used to configure the routed network profile. The list of network profiles available
to be assigned to a network path is filtered to match the subnet of the network path based on the subnet
mask and primary IP address selected for the network interface.
If you want to use an Edge or routed gateway in vRealize Automation reservations, configure the routed
gateway externally in the NSX environment and then run inventory data collection. For NSX, you must
have a working NSX Edge instance before you can configure the default gateway for static routes or
dynamic routing details for an Edge services gateway or distributed router. See NSX Administration
Guide.
Create a Reservation for Hyper-V, KVM, SCVMM, vSphere , or XenServer
You must allocate resources to machines by creating a reservation before members of a business group
can request machine provisioning.
Each business group must have at least one reservation for its members to provision machines of that
type. For example, a business group with a vSphere reservation, but not a KVM (RHEV) reservation,
cannot request a KVM (RHEV) virtual machine. In this example, the business group must be allocated a
reservation specifically for KVM (RHEV) resources.
Procedure
1 Specify Virtual Reservation Information
Each reservation is configured for a specific business group to grant users access to request
machines on a specified compute resource.
