Re: [Xen-users] how to use prebuilt images from jailtime.org?

["Gordon McLellan" <gordonthree@xxxxxxxxx>]

Hello Rudi,

>From that output, it looks like it has hung after the ssh service
starts.  I wonder about the VIF line in your xen config file.  Why is
it empty? Is vif = [ '' ] the same as accepting whatever default
adapter xen is configured to provide?  How long do you let it sit
there when it appears hung.  Depending on what it's trying to do, it
could take several minutes to time out, before moving onto the next
service.

You could try pressing "i" when prompted, and go through your services
one at a time, to see which one is hanging things up.

In regards to Windows, I have one hvm image of windows server 2003
which was configured using the virt-manager gui.  The install was
pretty straight forward, except that Windows was unable to detect my
PC type.  When I was prompted to press F6 to load additional drivers,
I pressed F5 instead, and selected "Standard PC".  As I understand it,
this tells windows which HAL to use for interfacing the NT kernel with
the underlying hardware.
