Key Concepts

G - L
gateway
Provides a routed connection between a virtual data center's network and an
external network. It can provide network services such as DHCP, firewall,
NAT, VPN, static routing, and load balancing.
guest operating system
An operating system that runs inside a virtual machine.
limits
In vCloud Director, you can specify limits for an upper bound for CPU and
memory resources that can be allocated to a virtual machine, but you might
waste idle resources. A virtual data center can allocate more than the
reservation to a virtual machine, but never allocates more than the limit,
even if there are unused resources on the system. When the memory limit is
unlimited, the default, the amount of memory configured for the virtual
machine when it was created becomes its effective limit in most cases.
