In this case, you should make the genesis for yourself.
Clone the xcatcore from git to your CentOS 6.4 and 6.5
cd xcat-core/xCAT-genesis-builder
./buildrpm
Thanks

There's no problem that mknb command created configuration files
in /tftpboot/pxelinux.cfg/, but which files were loaded during the boot
process.
Could you check that xnba.efi, xnba.kpxe and genesis.fs/genesis.kernel have
been installed in /tftpboot/xcat?

Well, in /opt/xcat/share/xcat/netboot/genesis/x86_64/fs/bin/dodiscovery
you'll find:

Sorry list denizens, another issue I ran into. I am trying to rediscover a
VM that I already once discovered with sequential discovery, but now it is
acting up. From my /var/log/messages log when I PXE-boot the VM:

So given this and the discovery discussion elsewhere, I've decided to
upload the genesis builder rpm. It's not particularly documented, so
here's a stab at how to make a new genesis out of some CentOS6 (or
obviously similar):
-Install rpm onto some 'donor' system.
-Run:
/opt/xcat/share/xcat/netbo
We are deploying a small cluster and when using sequential discovery the boot
to the genesis kernel fails with an unsupport CPU and a kernel panic. It looks
like the genesis kernel is from CentOS 6.3, is there a way to force it to 6.4
or 6.5?
Thanks,

Something else that should of course be a given, the /etc/passwd and

frequently instrumented topology cue that is pretty universal. For

I'm not clear anymore remembering what gave is the most grief back 2-3 years

Hi all,
we've got the situation that some users need passwordless ssh between

No, sorry, that does not answer question 3. I understand the numbering
scheme. We have 13 racks.
I just need to know where in the ordering process can we convince the folks to
