CentOS 5 is end of life and should not be used.

Luckily I can see from your kernel version that you don't really mean CentOS 5.1 as that would be just astonishingly irresponsible. That is 5.11 (kernel 2.6.18-400) which is still bad but at least it's not totally insane! Hmm, or maybe that's the kernel from the DVD you tried to install. And if it is really 5.1 then are you aware that that came out in late 2007 so it's now missing 11 years of really nasty security related patches and is most likely not even your system any more - it's so insecure that any passing hacker can probably break into it without much effort at all.

I would guess that you have attempted to boot a 64 bit DVD on 32 bit only hardware which would be the easiest explanation for the "Error 13: Invalid or unssupported executable format" error message.

Bottom line, you should really be replacing that system with a new install of a supported release. Currently the best bet for that would be to migrate to CentOS 7 as CentOS 6 is already on its way out and only has about 2 years of security-only-updates left before it goes EOL in 2020.

You should however be able to install the non-xen kernel by booting your existing system and pointing your yum repos to vault.centos.org and then installing kernel not kernel-xen.

The last version of CentOS 5 was 5.11 and it was released in late 2014. All of CentOS 5 went EOL in March 2017 and has received zero updates since then. That means it suffers from all of the various intel processor side channel vulnerabilities that can be exploited to retrieve information on your system that should be hidden and secure - like passwords, certificates, private keys etc etc.
CentOS 5 died in March 2017 - migrate NOW!
CentOS 6 goes EOL sooner rather than later, get upgrading!
