This is recommended both to help to ensure that network or DNS failures cannot impact MAAS management of servers, and for HA; if you run multiple rack controllers, MAAS will need to select which one to communicate with the BMC on, and can do that more reliably if it is on a directly-attached IP subnet, specified by an IP address. If MAAS cannot make that determination, if should attempt to fall back to trying to determine if the BMC is routable from a rack controller. (It sounds like that fallback might be happening in your case; if that's true, we could have a bug.)</div><div class="yiv3444267817gmail_extra"> - Are you specifying a hostname or IP address for your BMC?</div><div class="yiv3444267817gmail_extra"> - Is the BMC connected directly to a subnet configured on the MAAS server, or is it only available via routing? (You can use "ip route get <bmc-ip-address>" to determine that.)</div><div class="yiv3444267817gmail_extra"><br clear="none" class="yiv3444267817"></div><div class="yiv3444267817gmail_extra">(2) In order for DHCP (and, thus, PXE booting) to operate, the appropriate VLAN must be enabled for DHCP management in MAAS, and a dynamic IP range must be set up for [a] subnet(s) on that VLAN. If MAAS is nether responding to DHCP nor TFTP requests for PXE booting, check that DHCP is enabled on the appropriate VLAN. (Usually to do this, you browse to it under the Subnets tab and click on the 'untagged' VLAN that is displayed next to the subnet(s) you wish to manage.) If the network model in MAAS does not match your physical topology, MAAS might not enable DHCP on the correct interface. So it would be good to double-check that.</div><div class="yiv3444267817gmail_extra"><br clear="none" class="yiv3444267817"></div><div class="yiv3444267817gmail_extra">(3) What specific version of MAAS you're using. (We should really print that out in the logs, to be honest.) From the logs, it looks like at least 2.1.
