Re: [Xen-users] Newbie question on network and VM management

Thanks a lot Simon and Ian!

I am following the examples from the book -Âhttp://www.nostarch.com/xen.htm

The directiveÂroot = '/dev/xvda ro' helped a lot.

For some reasons I got presented the installation screen

Welcome to CentOS for x86_64

          ââââââââââ Choose a Language ââââââââââ

          â                   â

          â What language would you like to use â

          â during the installation process?  â

          â                   â

          â   Catalan        â    â

          â   Chinese(Simplified)  â    â

          â   Chinese(Traditional)  â    â

          â   Croatian        â    â

          â   Czech         â    â

          â   Danish         â    â

          â   Dutch         â    â

          â   English        â    â

          â                   â

          â        ââââââ        â

          â        â OK â        â

          â        ââââââ        â

          â                   â

          â                   â


 <Tab>/<Alt-Tab> between elements | <Space> selects | <F12> next screen

Do you know how to troubleshoot that?

The whole idea of my exercise is to get familiar with the dimU provisioning. I want to script that processÂ

so I can easily create several domUs on demand.Â

It just says that the process "init", with pid 1 crashed on cpu 0 and
gives the kernel version.

This is missing any kind of root=/extra=/cmdline= or bootloader=
statement, which would result in a root= on the kernel command line. So
the kernel has no way of knowing which partition contains a root
filesystem. Please check the wiki for numerous examples of how to
install a guest (even Centos specific ones) which have examples of
configuration files.
