Xen doesn''t boot on grub2 or xend doesn''t start

hi guys,

It''s my first time here and in a mailing lists, I only participated in
forums before. Please, If I make a mistake you should advise me. Let''s
go!

I was reading "xencommons not start" in a Remus Forum in order to
install
Remus.
Well… I followed the tutorial <
http://remusha.wikidot.com/configuring-and-installing-remus>, I reboot in
xen_unstable and I had a error message:

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

then I redid tutorial after "Adapt Grub" and in a moment I do command:

# /etc/init.d/xend start
xencommons should be started first.

but I had done "/etc/init.d/xencommons start" before and no error
message
returned !!!???

I also tried insert modules manually (coz in other mailing list said to put
some modules - see my setups after this mail) but I had:

# modprobe xen-evtchn
FATAL: Module xen_evtchn not found.

Please, help me
Thanks.

PS: I''m sorry to my English, coz I''m brazilian.

My setups are:

- fdisk

So xen event channel support is not compiled as a module? 
is it enabled at all in your dom0 kernel config?

Re: Xen doesn''t boot on grub2 or xend doesn''t start

Hi Pasi,

thank you for reply.

I''m using Debian Squeeze, and I''m compiling Xen from source
(.tar.gz). I
ran "make install-tools PYTHON_PREFIX_ARG=" to install Xen.

Notice: I couldn''t run in xen_unstable or dom0 then I returned to
install
environment (Debian Squeeze)

My attempt with modules and now with xenstored command (oxenstored command
works) was in Debian Squeeze. In this case I think I can''t load these
modules or run this command, but I''m not sure. Then your questions can
not
be in this scope. What do you think?

Thanks, Eduardo

Re: Xen doesn''t boot on grub2 or xend doesn''t start

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

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

hi,

for boot order, if manually set:
***
update-rc.d xencommons defaults 19 18
update-rc.d xend defaults 20 21
update-rc.d xendomains defaults 21 20
update-rc.d xen-watchdog defaults 22 23
***

and dont forget in /etc/default/grub
***
# SET THE DEFAULT BOOT KERNEL, NUMBER COUNTED FROM THE TOP BEGINNING WITH 0
GRUB_DEFAULT=10
# SOMETIMES IS NICE TO HAVE FIX MEMORY ALLOCATION TO AVOID CRASHING IF ALL
MEMORY IS USED
GRUB_CMDLINE_XEN="dom0_mem=1024M"
***

thanks walter

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

Walter,

thank you to reply.
I tried You suggested, but it didn''t work. More some idea?

Pasi,

I have posted in xen-devel coz in "Xen Users Netiquette <
http://wiki.xen.org/wiki/XenUsersNetiquette>" advise to report problems
about unstable/testing xen versions there. But, it''s OK, I just wanna
resolve my problem. :)

Let''s go... I really tried to fix the grub but I couldn''t.

my grub.cfg is after this mail

Thanks, Eduardo

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

I''m just wondering why the active entry under ###MY ATTEMPT uses msdos1
as
the partition, but doesn''t have "insmod part_msdos". Since
the entry
without Xen has it, that might explain the error: couldn''t open file
problem.

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

Kyle,

I tried all of the ways. I inserted "insmod part_msdos" too. I think
the
kernel 2.6.32.40 can''t boot in multiboot, and perhaps it must be set
up,
but I don''t know how do this.
I read others users can do only chanded the kernel

thanks
