# Subnets
# -------
# Subnets define at least a prefix used to validate static addresses
# associated with hosts.  Additional parameters may be passed, in particular
# a gateway and nameserver must be specified for a provisioning network.
# These will be used to pass static address information to the preseed.
# Default parameters for a subnet can be overridden at the host network
# definition.  Additional options can be specified which will be appended to
# the network configuration file.

  core-platform-services:

# Hosts
# -----
# Hosts define individual virtual machines identified by their fully
# quallified domain names.  When refered to in the DSL a host will be
# provisioned if not yet.  This will add A and PTR records automatically
# to a DNS server defined for the domain.  The machine will then be
# provisioned on a hypervisor.  Defaults can be provided to select the
# amount of memory and number and size of disks, default root password
# associated with the VM used for provisioning (if blank it will be
# generated ephemerally), and a kernel image location.  Parameters can
# be overridden on a per host basis.  Each host also defines a hash of
# metworks to provision which map to subnets defined above.

# DNS
# ---
# DNS objects refer to nameservers for specific domains.  If the nameserver
# for a domain has been instantiated and a host that domain with a network
# in a specified subnet then the system will automatically add A and PTR
# records.  Multi-homed machines which require DNS entried for each network
# are not supported.
