DHCP Reservations

[hydrian]

Being able to define a DHCP IP reservation based on MAC address for Internal and NAT Networks. This is extremely useful having a reliable IP of r guest before the OS is installed. Think automated builds.

Running an external DHCP server is not always easy or even possible. Try to to install a DHCPd server on a Windows or Mac desktop....

That would be indeed useful. Maybe for now a workaround like manually changing the corresponding leases file will be sufficient for you? Have a look at the VirtualBox home directory (on Windows it's /Users/USER/.VirtualBox, on Linux either $HOME/.config/VirtualBox or $HOME/.VirtualBox) and look for NETNAME.leases where NETNAME is the name of the network. This file contains active leases. The DHCP server reads this file on startup (NOT at runtime!.

I know it is very old ticket but in libvirt I can do something like below when defining a network, is it possible to do something like this in virtualbox?

<network>
  <name>test1</name>
  <uuid>79d21e39-30b0-4367-a96d-842cf7887ad7</uuid>
  <forward mode='nat'>
    <nat>
      <port start='1024' end='65535'/>
    </nat>
  </forward>
  <bridge name='tt0' stp='on' delay='0'/>
  <mac address='52:54:00:58:5f:44'/>
  <domain name='tt.testing' localOnly='yes'/>
  <dns>
    <srv service='etcd-server-ssl' protocol='tcp' domain='test1.tt.testing' target='test1-etcd-0.tt.testing' port='2380' weight='10'/>
    <host ip='192.168.126.10'>
      <hostname>test1-api</hostname>
    </host>
    <host ip='192.168.126.11'>
      <hostname>test1-api</hostname>
      <hostname>test1-etcd-0</hostname>
    </host>
  </dns>
  <ip family='ipv4' address='192.168.126.1' prefix='24'>
    <dhcp>
      <host mac='82:7d:df:54:21:62' name='test1-master-0' ip='192.168.126.11'/>

      <host mac='e2:14:06:fa:79:79' name='test1-worker-0-n8dtz' ip='192.168.126.51'/>
    </dhcp>
  </ip>
</network>
