The result is the same as Gokalp's. I discovered why this is happening. Here's the result of running modinfo on my system for both kvm and kvm-intel: turbotaz:/lib/modules # modinfo kvm kvm_intel filename: /lib/modules/2.6.25.11-0.1-pae/weak-updates/lib/modules/2.6.25.5-1.1-pae/weak-updates/kvm.ko license: GPL author: Qumranet version: kvm-63 srcversion: 110E834CDB3B229EE35C063 depends: vermagic: 2.6.25.5-1.1-pae SMP mod_unload 586 filename: /lib/modules/2.6.25.11-0.1-pae/kernel/arch/x86/kvm/kvm-intel.ko license: GPL author: Qumranet srcversion: 26AB3206D8CB359A69D697D depends: kvm vermagic: 2.6.25.11-0.1-pae SMP mod_unload 586 parm: bypass_guest_pf:bool Note the difference in path and vermagic. It seems there is an earlier copy of kvm.ko out there that is being favored in the module search path over /lib/modules/2.6.25.11-0.1-pae/kernel/arch/x86/kvm/kvm.ko. If I use insmod on that and modprobe kvm-intel, both modules load correctly. I'm new to openSUSE and know very little about its package management. I don't understand "weak-updates", so that's as far as I can go at the moment. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

If KMPs are installed for a $MAJOR.$MINOR.$PATCH compatible kernel, then they are used instead of modules from the kernel package. You're seeing kABI-incompatible changes. The thing is that I can't see where the incompatibility was introduced. There haven't been any KVM changes in the openSUSE 11 kernel. I just rebuilt the kernel against the original symbols we generated at release time, and none of the changes would affect KVM at all. In the interim, the best way to fix it is to update or remove the KVM KMP. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

So thats not going to be an option for most people. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The dependencies need adjustment there. It *is* safe to do an rpm -e --nodeps <kmp>. Strangely, the package does depend on kernel-syms. An updated KMP should've been generated with the updated kernel package. Bruce - Is there a particular reason that the kvm package depends on the KMP? Is the version of the module more recent inside the KMP? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
