Marcus Sorensen commented on CLOUDSTACK-548:
--------------------------------------------
Maybe what you want is the ability to pass a mac address to deployVm? You can
already select which IP address a VM will get when you create the VM, but it
doesn't sound like you're using cloudstack-provided DHCP (your reference to
centeral DHCP servers). If you have your own DHCP servers, then you could
create a network offering without DHCP/DNS services, create a network based on
that offering, and then specify a mac when you run deployVM in order to select
the IP it gets from the central DHCP server (if the feature were added).
I sort of get the issue you have, but I'm struggling to understand how you want
to fix it, since the MAC addresses are dynamically generated upon VM creation,
and you can already specify IP on vm deployment and specify an IP pool for the
network when you create it( and only if you are using CloudStack provided
DHCP). Do you just want a MAC pool associated with a network, or do you want to
specify an exact MAC for a VM upon deploying it?

> 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.
