[ipxe-devel] Track bug: https://bugs.centos.org/view.php?id=8295, failed to setup an ipxe server

[hhei]

Hi,

Thanks for your responding!

I have tried it as your suggestion, result is not good.

1. After update dhcpd.conf as your suggestion, uefi does not work, and 
bios does not work well, it will download undionly.kpxe again and again.
2. I change the section to the following description, and bios works 
well, but uefi does not work well, and the result is the same as mentioned(
After type the "boot" command from the command-line (not from the 
script), that I do not see an error-message, then boot from pxe network, 
then load ipxe.efi, be stuck in loop, after 3 times, guest turns off.
)

-------------------------------------------
   if option arch = 00:07 {
       if exists user-class and option user-class = "iPXE"
       {
           filename "ipxe.cfg";
       }
       else {
           filename "ipxe.efi";
       }
   }

   else {
     if exists user-class and option user-class = "iPXE" {

       filename "ipxe.cfg";

     }

     else {
       filename "undionly.kpxe";
     }

   }
-------------------------------------------

After tried many times, I thought it was related to "boot", why boot 
command can not load vmlinuz correctly, but kernel and initrd command 
can exec successfully, and "imgstat" command seems right with correct size.


Best Regards
hhei
