Re: [Xen-users] Tainted kernel module?

Some time ago, I noticed that whilst I had upgraded to Xen 3.1
(kernel 2.6.18-xen), I'd forgot to upgrade the paravirt DomU .cfg
kernels from 2.6.16-xen to reflect this. So, I upgraded the DomU
kernels & ran into issues with mounting devices, and the ext3 module
not being available.

After a bit of faffing about, I managed to sort this out and load the
ext3 module.

However, now, in the domU's dmesg, I see...
ide_generic: no version for "struct_module" found: kernel tainted.

Is this anything to be concerned about? How can I fix this?

Running RHEL 4.5 Dom0, with CentOS 4.5 guests.

Is some of this perhaps because you didn't upgrade the modules in the initrd
being used by the guests?

Hmmmm, explain? I did a..
mkinitrd -v --with=ext3 /boot/initrd-2.6.18-xen.img 2.6.18-xen
and copied the /lib/modules/2.6.18-xen/ directories from Dom0 to DomU. This was all prior to getting the 'kernel tainted' message.

FWIW, cat /proc/sys/kernel/tainted in DomU gives a "2" which apparently means a module load was enforced in SUSE (couldn't find the relevant info for RHEL). "--with=ext3"?
