Dear All,
The majority of the machines we use are running some variant of RHEL 4.4.
However I have two SuSE 9.3 virtual machines that were previously configured
correctly for Xen 2.0.7 in loopback files.
I''ve recently moved them to Xen 3.0.3 using LVMs but get errors such
as:
# /etc/init.d/sshd restart
Shutting down SSH daemon done
Starting SSH daemonmodprobe: FATAL: Could not load
/lib/modules/2.6.16-xen3_86.1_rhel4.1/modules.dep: No such file or directory
modprobe: FATAL: Could not load
/lib/modules/2.6.16-xen3_86.1_rhel4.1/modules.dep: No such file or directory
This results at boot time in an error that forces the runlevel to change
from 3 to 4 which is a standalone mode that will have no sshd or network
turned on. If I use "xm console" and log onto the relevant hosts I can
start sshd and network and get the machines working but with the nasty
error messages above. Does anyone know of a patch to fix this, or do I
have to have a vmlinuz specially built for SuSE 9.3?
Currently my automatically loaded xenU /etc/xen/auto/suse9-vm contains:
kernel = "/boot/vmlinuz-2.6.16-xen3_86.1_rhel4.1"
I am surprised the RHEL4.1 RPM doesn''t work, because it works for
CentOS
4.4 and RHEL 3.0.7.

Re: [Xen-users] SuSE 9.3 XenU using the Xen 3 RHEL4.1 RPM
Hi Ulrich,
Thanks your suggestion gets rid of the annoying references to not being
able to find the modules. However it still doesn''t allow the machine to
come up in runlevel 3 which is what I want. There are also some errors
at the start about not being about to create /dev/mapper/control,
although it seems to exist already with the correct permissions.
The errors look as follows:
Activating device mapper...
FATAL: Module dm_mod not found.
device-mapper kernel module not loaded: can''t create
/dev/mapper/control.
failed
showconsole: Warning: the ioctl TIOCGDEV is not known by the kernel
I couldn''t find any easy solution.

So either a sequencing problem, or a timing problem. Maybe add a sleep when the mapper is loaded. Part of my system''s startup says: Activating swap-devices in /etc/fstab... doneStarting udevd done Activating device mapper... done Loading required kernel modules doneStarting MD Raid done Waiting for udev to settle... Scanning for LVM volume groups... Reading all physical volumes. This may take a while...

In my SLES10 system I have: INITRD_MODULES="amd74xx mptsas processor thermal fan reiserfs dm_mod edd" See "dm_mod" is explicitly mentioned.> device-mapper kernel module not loaded: can''t create /dev/mapper/control. > failedAlso: lrwxrwxrwx 1 root root 16 Nov 23 09:58 /dev/mapper/control -> ../device-mapper crw-rw---- 1 root root 10, 63 Nov 23 09:58 /dev/device-mapper> showconsole: Warning: the ioctl TIOCGDEV is not known by the kernel > > I couldn''t find any easy solution.Dig and you will find something ;-) Regards, Ulrich _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
