seem I have find the problem.

because I test in vmware workstation, 

https://redmine.pfsense.org/issues/5046

add 
 else if option pxe-system-type = 00:09 {
                  filename "grub/grub-x86_64.efi";


below is my dhcp template.


     class "pxeclients" {
          match if substring (option vendor-class-identifier, 0, 9) = "PXEClient";
          if option pxe-system-type = 00:02 {
                  filename "ia64/elilo.efi";
          } else if option pxe-system-type = 00:06 {
                  filename "grub/grub-x86.efi";
          } else if option pxe-system-type = 00:07 {
                  filename "grub/grub-x86_64.efi";
          } else if option pxe-system-type = 00:09 {
                  filename "grub/grub-x86_64.efi";
          } else {
                  filename "pxelinux.0";
          }
     }
}


now vmware is working. later I try use pc to test.

I believe I use the newest loader

# md5sum grub-x86_64.efi

I use the fefault ks file for centos 7

You might want to try updating the Cobbler loaders, the EFI bootloaders have been updated recently.
Try using `cobbler get-loaders` or download them manually from https://github.com/cobbler/cobbler-loaders and place them in /var/lib/cobbler/loaders

Hope this helps!

Cheers,
Jörgen
