How to set compute and controller nodes

asked 2016-02-14 22:54:43 -0700

Hi All,

I have created a virtualbox VM & booted with arno fuel iso image and made necessary bridge configurations. My Fuel master is ready. I see 0 Total nodes & 0 Unallocated nodes on fuel dashboard. Next step is to bring the compute and control nodes & make them PXE boot[as per arno instructions]

For the compute and controller nodes, again I have created a virtualbox box VM[with no os selected] & changed the boot order [1-Network, 2-HD] to make PXE boot. When I pressed F12,

iPXE (PCI 00:0D.4) starting execution...ok iPXE initializing devices...ok

iPXE 1.0.0+ -- Open Source Network Boot Firmware -- http://ipxe.org Features: DNS TFTP HTTP PXE PXEXT Menu

net0: 08:00:27:e8:e0:aa using 82540em on PCI00:03.0 (open) [Link:up, TX:0 TXE:0 RX:0 RXE:0] DHCP (net0 08:00:27:e8:e0:aa)... ok net0: 172.27.3.12/255.255.255.255.0 gw 172.27.3.1 Next server 172.27.0.10 Filename: 172.27.0.10\REMINSBoox86 tftp://172.27.0.10/172.27.0.10%5CREMINST%5CBoot%5Cx86............Connection timed out ( http://ipxe.org/4c126035 ) No more network devices FATAL: Could not read from the boot medium! system halted.

I something wrong in my steps? Please correct me.

can you confirm that your FUEL MAster VM NIC and the VM that you just created are on the same BRIDGE on your HOST machine?

Also - you should make sure that there are no other DHCP servers on the same subnet as the FUEL PXE network, if you need, create two VM nics and two networks, one external and one internal.

Cheers, Daniel

Daniel, Thanks for responding. I confirm that both are in the same L2 segment. Link below shows the document on complete installation of fuel master setup & nodes bringup. Request you to have a look & advice. https://drive.google.com/file/d/0B5h_xNT4vp72S3dzZ2tyNzY4czQ/view?usp=sharing Thanks.

heya. I looked at your shots and things "look" ok - however i dont use virtual box (i use KVM, so maybe there is something there - i think VirtualBox uses linuxbridges anyway).. So can you send me the following: from FUEL node - ifconfig -a From your Jumphost (with both the FUEL and Compute running)

Sorry continuing: From FUEL - ifconfig -a From your JUMPHOST (with everything up) send : brcrtl show ifconfig -a from what i can see the Bridge and TAP functions are built into VirtualBox, so you should be fine. http://www.bgevolution.com/blog/pxe-network-boot-virtualbox/ might help.. bu

but probably not - since i think you have it correct. I suspect it is something on the host with the bridges but would need the output above to be sure and tell you what to do next.

Daniel, the ifconfig output is available in the document. Link below for your ref, https://drive.google.com/file/d/0B5h_xNT4vp72ZEYySzg0UGJ6QVE/view?usp=sharing

If you are on Ubuntu, why virtualbox? YOu can use KVM and virt-manager (if you like guis)? - not that there is anything wrong with VB, i just dont use it much (except when on Windows and there isnt a ESxi key nearby).

http://opnfvericsson.ca/FUEL_KVM_SETUP.pdf its doesnt show how to create the virtual networks that you should need (you should really have at least two (if you are going to use vlaninig" or 5 if you want to go completely flat (ADMIN, MGMT, STORE, PUBLIC, PRIVATE).you can create them in the gui to

Hey there. you can do it two ways. first you can do from the command line "brctl addbr fuel1", "brctl addbr fuel2", etc, etc for all 4 bridges then you can do brctl addif to chain up external one . or.. when you open vit-manger, on the opening page, click Edt Connection pre. in there add networks

muck like you do in VB add networks or in Esxi..make sure the netwroks are host only isolated ones. generaly i do 4 bridges, fuel1 (ADMIN/PXE), fuel2 (PRIVATE,STORAGE (VLAN)), fuel3 MGMT, fuel4 PUBLIC - so when you create your VMs you can decide what network topology you want.

lmcdasm ( 2016-02-22 14:43:19 -0700 )edit

for getting out the Public world, you should probably put your FUEL's VM's second network card on a bridge and have it get an IP on your public netwokr is the easiest thing..
