Unable to boot Fog from PXE

[swaroop]

Hi

I have successfully installed latest Fan on CentOS 7 , and then added a host and create a image.

Then create a task to upload image. Also on my DHCP server i have add 66 & 67 as Server IP & undionly.kpxe.

and when i boot host through PXE , i can see that the system get an IP address but further nothing happens.

I tried to test TFTP Server and it is working , i can get the file from other systems through TFTP client.

Please help !!! Thanks in advance …

Is there an error message displayed before it continues to the system? Something like PXE-E32 or similar?

[swaroop]

Thanks for the quick reply.

I tried to check the error but its so fast switching the screen , that i am able to see it.

[Tom Elliott]

@swaroop because you’re on centos 7, is selinux running? What about a firewall?

[swaroop]

Both selinux and firewall is disable .

[Tom Elliott]

so you never see the iPXE part, just PXE then system booting?

[swaroop]

Hi

Now i tried with virtual box server and i found that after getting the IP from DHCP Sever , it shows an error " DCHP failed hit “s” for the ipxe shell.

[Tom Elliott]

@swaroop The failed part is because it’s hitting the menu, but not exiting to boot to the first device yet.

Is it more likely your server timeout for pxe is just too short?

[swaroop]

@Tom-Elliott No

[Tom Elliott]

@swaroop What is the PXE Menu timeout set to?

[swaroop]

@Tom-Elliott i didn’t set it till now. can you please help to do that.

[Tom Elliott]

Can you ensure the network cable is good please? Either that or, if this is a VM make sure it’s not a natted connection, but a bridged one.

??? I know its late but, why am I seeing two different ipxe kernels running?

I looks like one ipxe kernel is chain loading to undionly.kpxe. And its the second kernel that is not picking up a dhcp address. Are we loading and older pxelinux.0 that is chainloading to a fog version of unidonly.kpxe? It makes me think that there is some old dhcp settings with a DHCP Proxy somewhere.

@george1421 Just my guess, this particular VM is virtual box.

Yes, Tom is right I think. Virtualbox is definitely using iPXE as PXE ROM. That’s why you see iPXE chainloading iPXE…

@swaroop Interesting that the first iPXE is able to get an IP via DHCP but the second is not. Can you please enable network tracing for this VM and upload the PCAP file to the forum here.

@Tom-Elliott Thanks a lot … it worked … :
