Subject [jira] [Created] (CLOUDSTACK-548) Static DHCP leases - MAC address pool

------------------------------------------------

             Summary: Static DHCP leases - MAC address pool
                 Key: CLOUDSTACK-548
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-548
             Project: CloudStack
          Issue Type: New Feature
            Reporter: Ioannis Charalampidis


It would be very useful if there was a way to specify a MAC addresses / IP address pool for
a particular network offering. This way, when a VM starts it gets a static, predefined lease
from a DHCP server in the infrastructure's network.

For example, we are using CloudStack in a test cluster at CERN, but due to our network restrictions,
each machine on the network must be pre-registered. With this pool feature, it will make possible
to register all the possible VMs in advance and get an IP from our central DHCP servers.

In order to avoid expensive IP address lookups it should possible to pre-define an IP address
for each MAC address. This is more or less the same parameters that someone would put in a
dhcpd configuration for static leases.

This should also be possible for the system VMs... this does not cancel-out the use of Virtual
Router / Security Groups. On the contrary, they will need the static lease in order to be
granted access to the infrastructure network.
