Virtual Private Cloud OnDemand Networking Guide

Network Connectivity for Virtual
Machines 4
When deploying a virtual machine from Virtual Private Cloud OnDemand, the virtual machine is created
without a network. A virtual machine without a network is isolated from communicating with other virtual
machines and servers both in and outside of the service.
When you create a virtual machine, you have the choice of assigning the virtual machine to a routed
network or to an isolated network. An isolated network does not have Internet connectivity. Isolated
networks have an internal subnet assigned and an IP Range from which virtual machines can obtain IP
addresses.
When you create a virtual machine, you have the following choices for how the virtual machine obtains an
IP address:
n
DHCP: if you use DHCP to get an IP address from the DHCP pool, the gateway functions as a DHCP
router.
n
Static IP Pool: by choosing to obtain an IP address from the Static IP Pool, the virtual machine gets an IP
address from the range configured for the network.
n
Static Manual: you enter the IP address manually when creating the virtual machine and specifying the
networking configuration.
NOTE To use the Static IP Pool or Static Manual networking options, VMware Tools must be installed on
the virtual machine you are creating. You can use DHCP to provide an IP address regardless of whether
VMware Tools are installed on a virtual machine.
See “Allocation of IP Addresses,” on page 11 for more information about how you allocate IP addresses to
virtual machines.
For information about VMware Tools, see the following documentation:
