Could someone please let me know whether PXE server configurations are available by default during fuel master installation or do we need to configure it manually in the fuel master.

Thanks in advance!!!

When you boot the FUEL ISO, the installation instruction outline that you press Tab and set "showmenu=true", this will bring you to the FUEL installation confguration screen. Therein you will find the PXE settings (they default to - IP of FUEL and the PXE boot range is (I think - you have to check to be sure).

To answer your question - yes, fuel comes up with a PXE configuration by default (you can see it with the steps above if you go into showmenu) and this is configurable to set the subnet and range of hosts you want to support.

Thank you so much for your reply. If there are 2 PXE boot servers in the same network (One from fuel and another is a for a different purpose). Could you please let me know if there is a way to select the one we need from the PXE client ?? I am using virtual machines for each node.

hello. Its not advised to have two PXE servers (nor DHCP servers on the same subnet, in fact its a requirement of FUEL and if FUEL detects the presence of a DHCP server it will throw a warning. Since PXE is a hand-free mechanism - there is no way to "pick" which one.

As well, the FUEL subnet should be a private, untagged one - so im not sure how you would have two PXE servers there. Since PXE is done via ARP and at boot time, there is no way to "PICK" on - since it would be the first PXE server to repsond to the ARP that gets the role. Also - having two will

cause you serioues issues later on as well (during reboots, your install might be picked up by the other and you have a failure during deployment). Best answer, turn off the other one if you cant provide the private subnet - you shouldnt be setting up your FUEL on your Datacenter public network

anyway - since then your FUEL server might start PXE/DHCP offering other nodes that reboot in that subnet (and then people will get made at you for hijacking their servers ;P).
