Re: [Xen-devel] Xen doesn't boot on grub2 or xend doesn't start

[José Eduardo França <jefranca@xxxxxxxxx>]

Pasi,

I didn't really understand when You said "I was talking about dom0 Linux kernel, not about Xen", coz I understand you must be in xen to access dom0.
Look: in my grub2 I have these options in grub2:

Xen Unstable / Debian Squeeze kernel 2.6.32.40
Debian GNU/Linux, with Linux 2.6.32.40
Debian GNU/Linux, with Linux 2.6.32-5-686

I select first option and the system returns:

error: couldn't open file
error: you need to load the multiboot kernel first

The second option is in graphical environment but keyboard and mouse don't work there. I thought You said to enter within this option (but I think this option is not important)

And the third option is my environment where I compiled and installed xen and Debian GNU/Linux, with Linux 2.6.32.40.
Here I do command "# /etc/init.d/xend start" and the system returns "xencommons should be started first", but I had done "/etc/init.d/xencommons start" before and no error message returned !!!???

and then... what do you think?

Eduardo
