Re: [Xen-users] Programatically checking if we''re in a domU or dom0
Hi, I''m not sure if I see exactly what you mean. I did change the hostname of each domU in the /etc/hostname of each domain. For example XX for dom0, XX-domU1 for my first domU , XX_domU2 for the second one and so on. Then in each console I have a different name. Besides it''s possible to check the /etc/hostname for the U extension or what ever you have considered for the unprivileged domains name. Did I get your question?
