Re: [Xen-users] Is grub menu supposed to work over the serial console, in Xen 4.0.1?

[Steven Timm <timm@xxxxxxxx>]

Do you also have a line in grub.conf of the form

serial --unit=0 --speed=115200
terminal --timeout=10 serial console

I don't have xen 4.0.1 myself and so can't test it with that,
but this functionality is part of grub and shouldn't matter
whether you are using Xen or not.  At this state you have not
loaded anything that is xen-dependent.
