[Xen-users] grub boot problem

Hi,

I have a XEN installation on Debian Lenny. After a package update I
rebooted, and grub doesn''t start. The update replaced my grub.cfg, but
it
doesn''t work. When I installed the system, I ran into that problem
(grub
error message "You need to load the kernel first"). At that time I
found a
solution, changed grub.cfg, and it worked. I tried that settings again, but
it doesn''t work! I get the error:
error: unknown command `module''
I can boot only the unmodified kernel. Here is my grub.cfg:
#bad entry:
menuentry "Debian GNU/Linux, linux 2.6.26-2-xen-amd64" {
    set root=(hd0,1)
    search --fs-uuid --set 81a70335-a810-444e-9247-1255491ff0ee
    kernel /xen-3.2-1-amd64.gz dom0_mem=512M
    module /vmlinuz-2.6.26-2-xen-amd64 root=/dev/mapper/xen-xensys ro
    module /initrd.img-2.6.26-2-xen-amd64
##    linux    /vmlinuz-2.6.26-2-xen-amd64 root=/dev/mapper/xen-xensys ro
##    initrd    /initrd.img-2.6.26-2-xen-amd64
}
#working entry:
menuentry "Debian GNU/Linux, linux 2.6.26-2-amd64" {
    set root=(hd0,1)
    search --fs-uuid --set 81a70335-a810-444e-9247-1255491ff0ee
    linux    /vmlinuz-2.6.26-2-amd64 root=/dev/mapper/xen-xensys ro
    initrd    /initrd.img-2.6.26-2-amd64
}

Thanks, in advance.

Re: [Xen-users] grub boot problem

Thanks for your answer. I''ve already known the second link, I tried it
out.
I installed grub-legacy, and it works now. Maybe the syntax of the grub2
confused me, because, as I see now, in my post there is a kernel command,
but it is a grub1 command in a grub2 config file. I don''t want to try
it out
now, but maybe grub2 would work for me with the replaced command. It is not
a xen related problem, it''s my error. The only xen related problem is
that I
have to use ''module'' parameters in order to boot the xen
kernel.

Thanks, Tamas.

[Xen-users] xm dmesg question

Hello,

I''m have a system on which I have vt-d passthrough enabled. The system 
and the  passthrough feature works ok. However there are some messages 
in the log at startup which indicate a problem of some kind. I prints 
out a fault overflow (see snippet below).

Anybody know the cause and or impact of this messages?

openSUSE 11.1 64bit
xen : 3.3.1_18546_06-1.5 (other versions give the same messages)
mobo: intel dq45cb (latest firmware)
