I think you need to make a symbol link of ../rh/dracut_033 to you
netboot/centos dir too. This is a necessary for Centos 7 support. Let me
know the progress.
Thanks
Best Regards

No. I used the same procedure and it worked for Centos6.5. I am mainly
using this documentation:

Yes, I am running Centos7 on the management node. I think I know what the
problem is.
genimage uses dracut to create the initramfs for the image. But the xcat
module directory
(/install/netboot/centos7.0/x86_64/compute/rootimg/usr/lib/dracut/modules.d/97xcat/)
is empty! It is also not possible use the module scripts from my previous
installation (with Centos6.5) because the way the module scripts need to be
written with the version of dracut shipped with this version of Centos
seems to be slightly different from the previous ones.
For example, now check,install, installkernel etc are functions in the
module-setup.sh script, instead of being scripts themselves (as in the
previous version).
Nevertheless, I tried to copy the scripts from the previous 97xcat module
scripts (Centos6.5). It gives the following error:
installkernel failed in module xcat
#
cat
/install/netboot/centos7.0/x86_64/compute/rootimg/usr/lib/dracut/modules.d/97xcat/installkernel
#!/bin/bash
instmods nfs sunrpc
***Please note*** This is the installkernel script in the xcat dracut
module that was shipped with Centos6.5 NOT with Centos7

I am running XCAT 2.8.5. I had already the symlink suggested in the
solution to the bug you had pointed to. That was essentially because the
genimage script could not find dracut. In my case dracut cannot
find/install the 'xcat' and 'mlx_en' modules.

I am trying to create an image from Centos7.0.

I get the following messages:
