Well, as I mentioned in my original e-mail, I don't know where this flag comes from: "As you can see the kernel tainted flags say 'GF'. I have searched where this comes from, but can't find >>anything. We only run open-source stuff on these machines, so no scary binary only modules. Also, a dmesg|grep -i 'tainted' returns nothing, and cat /proc/sys/kernel/tainted returns '0'. Go figure... My guess is that some startup script uses 'insmod -f' while it's not needed." > > The kernel I'm using is here: > http://xenbits.xensource.com/linux-2.6.18-xen.hg.

As I understand it, these versions are based on the 'paravirt_ops' version of xen (whatever that may be) which is all quite new and untested. I'm a bit weary to try that out. But on the other hand, the current setup isn't working either, so I might as well try it. Thanks, Ronald. > Cheers, > Florian > > -- > : Florian G.
