If you''re more familiar with vmware/vbox terms, dom0 (the one with id = 0) is the "host", while domUs (the one with ID > 0) are "guests"> root@node1:~# xm console 0 > Can''t specify Domain-0What you want to do makes no sense. "xm console" is used to access domUs console from dom0. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I''m not sure it''s possible to connect to a Dom0 console.
Remember, xm
is not creating a console, it''s connecting to one which the xen
backend already knows about. My version of XM says this in the man
page:
"This uses the back end xenconsole service which currently only works
for para-virtual domains."
