Installation via PXE

Hi,
I am trying to install OpenSUSE 13.1 via PXE on VMware ESX. We are installing all out servers like that but with OpenSUSE I have a problem.
The entry PXE menu looks like this:

LABEL OSS13.1
MENU LABEL OpenSuSE 13.1
kernel linux/other/oss/linux64
append initrd=linux/other/oss/initrd64 install=http://OurWebServer/install/openSUSE_13.1_x86_64

In the directory on OurWebServer I placed the content odf the ISO, the files in linux/other/oss/ are downloaded from http://download.opensuse.org/factory/repo/oss/boot/x86_64/.

The server boots, linuxrc ist starting and it all I see are the three dots. When I press ESC and try to start the installation in LinuxRC manually I first get a DHCP error and after some seconds a “repository not found”. (When booting the server, it receives a IP-configuration.)

Is there a problem with the VMXNET3-driver? Did I do anything else wrong?

Greetings
Andreas

Is OurWebServer name or IP? I would try with IP to exclude name resolution issue.
