Cannot install Ubuntu or other Linux flavours on Citrix Xen Server

Citrix Xen sucks!

When U-try to install Linux stuff in its Xen servers, u'll get an error complaining errors like below:

‘

... the bootloader for this VM returned a error-did the VM installation succeed? Invalid_source Unable to access a required file in the specified Repository:file:///tmp/cdrom-repo-glsdp2/install/vmlinu Z.

‘

This is a bug of Xen and the real cause are the missing Boot order config for the new VM instance.

We can Fix it This (http://discussions.citrix.com/topic/237726-unable-to-install-linux-guest/):
