* Rejigger networking so the bridge has the MAC of the external interfacebaserock/richardmaw/openstack-v3-unrebasedRichard Maw2015-03-021-9/+20
| | | | | | | | | | This allows the subsequent DHCP request to get the same IP address back, which means it only needs one address for first boot, and the address can be pre-allocated by the DHCP server before deployment. This is needed for the floating address range to be allocated in some set-ups, such as our local one at the office, where a subnet in a different class is routed to the server.
* Ensure newly brought up devices are correctly configuredRichard Maw2015-03-021-17/+21
| | | | | | | | | This adds masking config for the virtual devices to prevent them from attempting to DHCP, and stops us from giving the ip of eno1 to the bridge device, since eno1's address was obtained by DHCP, so it's against the rules to statically allocate that address to an interface. Now, we DHCP for a new address for the bridge.
* Disable DHCP on bound iface and internal ifacesRichard Maw2015-03-021-3/+4

* Deallocate IP address from bound interface after bindingRichard Maw2015-03-021-0/+3
| | | | | | If we leave that interface with its address, then the routing table is incorrect, as it will try to send connections out from an interface that cannot handle them.
* After initial switching setup, switch DHCP to external ifaceRichard Maw2015-03-021-0/+15
| | | | | | | | | | After the external interface has been bound to Open vSwitch, we should not attempt to DHCP on it, as it won't receive the DHCP responses. Attempting to DHCP results in startup stalling on network-online.target, because systemd-networkd-wait-online.service looks at every network interface it should configure based on the [Match] sections, and waits for all of them to be configured by systemd-networkd, which will never finish if DHCP is broken.
