[kea-dev] Managing host reservations dynamically?

[Brian Rak]

Is there any way I can set DHCPv4 mac -> ip address reservations 
dynamically?  I have an environment where I pre-configure any possible 
DHCP lease, but these configurations can come and go at any time 
(providing DHCP to virtual machines - our management systems dictate 
which IP a particular VM uses, but the easiest way of configuring the VM 
is with DHCP).

I looked at the control-socket feature, but this seems to be limited to 
just statistics related commands (at least as of 0.9.2).

One option I might have is to use the 'Host Reservations in MySQL' 
feature that might be in 1.0, but I'd really prefer to not have to run a 
bunch of MySQL servers in order to achieve this. (management of all the 
necessary MySQL instances would be time consuming).

It looks like my best bet right now is to just modify the Kea config 
file and issue a reload.  Is there any downside to doing this regularly?

Is there a better approach here?
