7. Click assign more load balancing.
8. Select the load balancing rule you have created for the zone.
9. Click OK to confirm.
16.10. Using Multiple Guest Networks
In zones that use advanced networking, additional networks for guest traffic may be added at any time
after the initial installation. You can also customize the domain name associated with the network by
specifying a DNS suffix for each network.
A VM's networks are defined at VM creation time. A VM cannot add or remove networks after it has
been created, although the user can go into the guest and remove the IP address from the NIC on a
particular network.
Each VM has just one default network. The virtual router's DHCP reply will set the guest's default
gateway as that for the default network. Multiple non-default networks may be added to a guest in
addition to the single, required default network. The administrator can control which networks are
available as the default network.
Additional networks can either be available to all accounts or be assigned to a specific account.
Networks that are available to all accounts are zone-wide. Any user with access to the zone can
create a VM with access to that network. These zone-wide networks provide little or no isolation
between guests.Networks that are assigned to a specific account provide strong isolation.
16.10.1. Adding an Additional Guest Network
1. Log in to the CloudPlatform UI as an administrator or end user.
2. In the left navigation, choose Network.
3. Click Add guest network. Provide the following information:
• Name: The name of the network. This will be user-visible.
• Display Text: The description of the network. This will be user-visible.
• Zone. The name of the zone this network applies to. Each zone is a broadcast domain, and
therefore each zone has a different IP range for the guest network. The administrator must
configure the IP range for each zone.
• Network offering: If the administrator has configured multiple network offerings, select the one
you want to use for this network.
• Guest Gateway: The gateway that the guests should use.
• Guest Netmask: The netmask in use on the subnet the guests will use.
4. Click Create.
16.10.2. Reconfiguring Networks in VMs
CloudPlatform provides you the ability to move VMs between networks and reconfigure a VM's
network. You can remove a VM from a network and add to a new network. You can also change the
default network of a virtual machine. With this functionality, hybrid or traditional server loads can be
accommodated with ease.
