I have just started with Xen and I need some confusion cleared up. After installing Xen and starting up the system, when I logon via SSH the first time, I get the prompt with the servers usual name. After I login again I get the prompt with the VM''s name and that is what is getting me confused. Is the dom0 a Xen instance that is different instance from the main server, or does the main server become the dom0? Can they be logged on to separately? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Is it registering its network port with DHCP? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] Confusion between dom0 and main server?
dom0 is effectively like the "host" Linux. The "main server" that you installedf Xen into *is* dom0.
