I'm running Centos 6.5 and Cobbler 2.7.0 checked out from github:

[root@ops ~]# cat /etc/redhat-release

CentOS release 6.5 (Final)

[root@ops ~]# cobbler version

Cobbler 2.7.0

  source: c5a7bb2, Sun Apr 27 00:24:56 2014 +0200

  build time: Sat Apr 26 19:28:28 2014

My cobbler installation is able to successfully pxe boot systems on which I install CentoOS 6.5, so I know that it is working, but I am having difficulty with gpxe booting esxi5.5.

I have successfully imported the ESXi5.5 iso: VMware-VMvisor-Installer-5.5.0-1331820.x86_64.iso

I have installed the packages for gpxe, however, when I boot the machine on which I want to install ESXi5.5, I get the following error: 

Loading operating system
Configuration error while parsing /boot.cfg
Fatal error: 15 (Not found)  

Below is the distro report:

I have already read previous similar posts for previous versions of esxi5, but did not find those helpful:

Any help would be greatly appreciated,
