I am not sure if this is a bug. This is what I have found. I need to run XEN, so I have installed latest version of CentOS 6. Same as XEN from official repository, which is XEN 4.4.1 (in the time when it was installed). I have installed Cloudmin without any issue, but when I enter the interface it says:This system cannot be a Xen host : The required command xm does not exist. Perhaps the Xen software is not installed? Virtual systems cannot be created or added until this is fixed.
I have searched how to install xm, but it turns out that XEN is no longer use xm and xend but uses xl command.
How this can be fixed locally or is better to wait for an update?
