XCP is Open Source Xenserver. There are some security update for it so you should run
yum –enablerepo xcp –nogpgcheck update
and then reboot your server for the updates to take effect.
I’ve just set up a yum repo for XCP 1.6. In this repo I’ve included an
updated Xen hypervisor, which will resolve the issues mentioned in this
Citrix security advisory: http://support.citrix.com/article/CTX135777
Unfortunately, I haven’t signed the rpms in this repo, so you’ll have to
disable gpg checking when you update. If you would like to update your
hosts, run the command ‘yum –enablerepo xcp –nogpgcheck update’. Since
this is a Xen hypervisor update, you’ll have to reboot your hosts for
this to take effect.
