I have been using the syntax "xm create -c" from the beginning
since I was following the manual (in particular the ttylinux
example). Unfortunately all I see (in its entirety) is this:
[root@garlic xen]# xm create -c xmfc4
Using config file "xmfc4".
As soon as that single line is printed the hardware hangs up.
I do not think Xen even gets started enough to print anything
to a console.
The same is true when I try the ttylinux example. I only get
that single line and then the hardware hangs.
By the way, before I try starting a domU I see this:
