Hello guys,
I''m trying to run XEN installed from RPM''s packages on my
server with
SUSE LINUX Enterprise Server 9 (x86_64) kernel 2.6.5-7.257-smp and the
problem when I reboot is the follow:
VFS: Monted root (ext2 filesystem)
VFS: Cannot open root device "system/root_lv" on unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic = not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
I''ve searched on old posts, and tried to make other initrd image, but
without success :-(
This kernel works on my grub:
title Linux
kernel (hd0,0)/vmlinuz root=/dev/system/root_lv selinux=0 splash=silent
desktop elevator=as showopts
initrd (hd0,0)/initrd
This kernel don''t work:
title Xen
kernel (hd0,0)/xen-3.gz com1=115200,8n1 noreboot
module (hd0,0)/vmlinuz-2.6-xen root=/dev/system/root_lv ro maxcpus=1
console=tty1 console=ttyS0,115200n8
module (hd0,0)/initrd-2.6-xen.img
My RAID controller is:
0000:02:0e.0 RAID bus controller: Dell PowerEdge Expandable RAID
controller 4 (rev 06)
My fstab:
xen:~ # cat /etc/fstab
/dev/system/root_lv / reiserfs defaults 1 1
/dev/sda1 /boot reiserfs defaults 1 2
/dev/system/home_lv /home reiserfs defaults 1 2
/dev/system/logs_lv /logs reiserfs defaults 1 2
/dev/system/queue_lv /queue reiserfs defaults 1 2
/dev/system/tmp_lv /tmp reiserfs defaults 1 2
/dev/system/var_lv /var reiserfs defaults 1 2
/dev/system/swap_lv swap swap pri=42 0 0
Is this problem arround RAID and/or LVM?
Thanks!

Where can I find one kernel with this? Sorry, but I can''t understood how can I do this :( -- Tiago Cruz <tiagocruz@ig.com.br> _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Where can I find one kernel with this?I tried to recompile the kernel, and the result was: (XEN) Brought 4 CPUs (XEN) Using IPI Shotcut mode (XEN) *** LOADING DOMAIN 0 *** (XEN) DOM0 image is not a Xen-compatible Elf image. (XEN) (XEN) ************************ (XEN) Panic on CPU 0: (XEN) Could not set up DOM0 gest OS The problem is: Is this not the master OS? I''m not configured any guest yet... i''m trying to up the ''master'' kernel....

Are you building the Linux kernel in the Xen-tree? -- Mats> > Thanks! > > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users > > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
