[Xen-users] xen SUSE 9.3 ReiserFS domU not finding root fs
Hi,
I have trouble starting my domU on a suse 9.3 box. I use the xen that
shipped with suse.
I use file backed VMs and created the root and swap images. I used
mkreiserfs to format the image file and installed suse 9.3 via the YaST
module "install into directory for XEN". finally I created /etc/fstab
IN
the loop mounted image file:
/dev/sda1 / reiserfs defaults
1 1
/dev/sda2 swap swap pri=42
0 0
devpts /dev/pts devpts mode=0620,gid=5
0 0
proc /proc proc defaults
0 0
If I boot such a domU - it panics while booting saying something like:
"Not syncing root file system - rebooting in <1>". If I use an
image
file which was formatted with ext3 (again adjusted the /etc/fstab)
everything works fine and SUSE is booting. After a closer look I noticed
that the ext3 filesystem is used in ext2 mode only.
How do I use ReiserFS for my unprivileged Domains? Do I need an initrd?
How do I configure it? I tried the /boot/initrd-xen from suse and used
the following line in my config but it doesn´t seem to work too:
ramdisk = "/boot/initrd-xen"
Can anybody help?
thanks a lot!
Daniel

First look is at the /etc/sysconfig/kernel in your dom0 root file system. Mount it and look at that file, there should be a line like: INITRD_MODULES="reiserfs" Also, there was a thread in the list this week about problems with the mkinitrd, where the mkinitrd just kept using the modules for the old non-xen kernel, instead of the xen kernel. Gerd Knorr is one of the participants. -- Bye, Fernando Maior LPIC/1 31908 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Thanks for your help! That line "INITRD_MODULES="reiserfs" is in /etc/sysconfig/kernel the module seems to be loaded: ... ide: Assuming 50MHz system bus speed for PIO modes; override with idebus=xx Loading kernel/drivers/ide/pci/piix.ko Loading kernel/drivers/scsi/aic7xxx/aic7xxx.ko Loading kernel/drivers/scsi/megaraid.ko Loading kernel/drivers/ide/ide-disk.ko Loading kernel/drivers/cdrom/cdrom.ko Loading kernel/drivers/ide/ide-cd.ko Loading kernel/fs/reiserfs/reiserfs.ko Waiting for device /dev/sda1 to appear: ok rootfs: major=8 minor=1 devn=2049 Mounting root /dev/sda1 mount: No such device Kernel panic - not syncing: Attempted to kill init! <0>Rebooting in 1 seconds.. but something still goes wrong. Anybody uses XEN from the stock suse 9.3 with reiserfs? Is it correct to specify initrd for xen in the config file like this: ramdisk = "/boot/initrd-2.6.11.4-20a-xen"? thanks, dan>On 5/13/05, Daniel Netzer | zeroconcept.de <daniel.netzer@zeroconcept.de> wrote: > >>Hi, >> >>I have trouble starting my domU on a suse 9.3 box.

Far, far away from what people are saying in this list. The only thing I did different was to include iptables modules into the domU kernels. -- Bye, Fernando Maior LPIC/1 31908 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I just installed SuSE 9.2 into the Intel P4 2.4Ghz with 1GB RAM and about 40GB disk. The amount of RAM is what limits the number of xen domains running in the hardware. And I am not using Xen from SuSE, instead I downloaded the tar gz package and installed from source. Far better, IMO. -- Bye, Fernando Maior LPIC/1 31908 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

[Xen-users] Re: xen SUSE 9.3 ReiserFS domU not finding root fs
Everything is fine with my Suse93/XEN now. I used the rpms on the DVD and used file-backed (lopp-mounted) domU. That was a mistake. Lots of trouble with yast "installing into a directory for XEN" module. Now I use LVM and everything works. BUT after using yast for installing into a directory for XEN I had to MANUALLY COPY initrd-xen and kernel-xen to the newly created domU filesystem (have a look for the links in /boot - mine pointed to "nowhere"). After inserting "initrd-xen" everything is ok now. Hope that helps Dan _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
