------------------------------------------------
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.
