How to install additional software on xenserver 6.5?

Question

linux

I tried to put puppet-release on Xenserver 6.5 - it didn't work. Writes that the GPG signature error.

Install       1 Package(s)
Upgrade       0 Package(s)

Total size: 8.4 k
Is this ok [y/N]: y
Downloading Packages:
ошибка: rpmts_HdrFromFdno: Заголовок V4 RSA/SHA512 signature: BAD, key ID 4bd6ec30

I tried to turn off the check - more errors got out further.

# yum localinstall puppetlabs-release-6-11.noarch.rpm --disablerepo=citrix   --nogpgcheck

Total size: 8.3 k
Is this ok [y/N]: y

I tried to put epel - also errors, asks for libraries.

rpm -i epel-release-6-8.noarch.rpm

Someone found a way how to put extra. software on a machine with XenServer 6.5?
PS: Especially for those who believe that he is the "Captain".
I know it's a hypervisor.
I know that developers do not recommend installing third-party software on it.
The question is not about that. The question is HOW TO PUT.
Anyone who thinks that I'm wrong - you can not comment on anything, but bypass this issue.

Answer 1

As it turned out, the package base for XenServer 6.5 remained on the CentOS 5 branch. The minor release has changed. Now it's CentOS 5.10
According to Tobias Kreidl, from the Citrix forum, the next release of XenServer will be based on CentOS 7. Version 6 is being skipped.
So packages from rep for CentOS 5 are installed

Answer 2

What for?
This is a hypervisor. On it to be put VM. And if you need something on the hypervisor itself, this is done through api

Answer 3

It's better not to do this if the need arises - look aside separately CentOS separately Xen.org and building it from packages.
