connection timed out (http://ipxe.org/4c116035)

[psavarma]

Hi
I've setup openstack on my ubuntu os and i've created some instances in the openstack gui.
now when i open the console of this instance, an error appears telling it is not able to boot from rom and asking me to boot manually..

so i press cnt+B for manual booting and it asks me to boot using ipex, i follow the commands given in http://ipxe.org/start, when i try chain http://boot.ipxe.org/demo/boot.php command for boot
i am getting connection timed out (http://ipxe.org/4c116035) error

please help me boot this

ps
i also got http://ipxe.org/err/2d0c20 error for show hostname and show filemane commands

If this is a VM with iPXE ROM then you'll need for the second Ctrl-B prompt before you start doing things, or else your hardware is not completely initialized. You also need to issue a dhcp command before you issue the chain command, or else you have no network connection.

hello. i have also get stuck with this problem.It promts connetion time out.

I tried to use iPXE as a component of the automation software Razor.
Razor automatically generates a ipxe script in /var/lib/tftpboot , i.e,razor.ipxe.
The script is listed as follows:
-----------------------------------
#!ipxe
:n0
echo test0
isset ${net0/mac} && dhcp net0 || goto n1
echo net0 has DHCP
set dhcp_mac 01-${net0/mac:hexhyp}

:n1
echo test1
isset ${net1/mac} && dhcp net1 || goto n2
echo net1 has DHCP
set dhcp_mac 01-${net1/mac:hexhyp}

:n2
echo test2
isset ${net2/mac} && dhcp net2 || goto n3
echo net2 has DHCP
set dhcp_mac 01-${net2/mac:hexhyp}

:n3
echo test3
isset ${net3/mac} && dhcp net3 || goto n4
echo net3 has DHCP
set dhcp_mac 01-${net3/mac:hexhyp}

:n4
echo test4
isset ${net4/mac} && dhcp net4 || goto n5
echo net4 has DHCP
set dhcp_mac 01-${net4/mac:hexhyp}

:n5
echo test5
isset ${net5/mac} && dhcp net5 || goto n6
echo net5 has DHCP
set dhcp_mac 01-${net5/mac:hexhyp}

:n6
echo test6
isset ${net6/mac} && dhcp net6 || goto n7
echo net6 has DHCP
set dhcp_mac 01-${net6/mac:hexhyp}

:n7
echo test7
isset ${net7/mac} && dhcp net7 || goto s1
echo net7 has DHCP
set dhcp_mac 01-${net7/mac:hexhyp}


1
echo test-s1
chain http://192.168.228.31:8026/razor/api/boo...{dhcp_mac} || goto error

:error
sleep 15
reboot
--------------------------------------------

In general,the script tries to detect all network card in the server which has a dhcp service and return its mac address.


there are two NICs in my server,eth0 and eth1.I have disabled the dhcp service of eth0 by "deny unknown-clients" and allow eth1.

Here comes the problem:
connection time out .(in the attactment)
thanks !

The script seems correct, but you might have problem with STP causing timeout. You can extend the DHCP timeout value (can't recall which file it is in) by modifying the constant and recompiling iPXE. You should also have a look at the error URL iPXE gives you. Please post it here as well.
