Eg. if you run with a newer 2.6.27-2.6.28 kernel with the modules included, will you then benefit from using the modules from the latest KVM release together with the latest KVM userspace, or isn't it worth the effort? According to http://kvm.qumranet.com/kvmwiki/Downloads, it is required to use at least kernel 2.6.25 to run KVM userspace 76 or newer. Does this mean that no changes/bugfixes has been made to the KVM kernel module since 2.6.25? Or is it because all the major bugfixes are made in KVM userspace instead of the KVM kernel modules? And one last thing: When I compile the latest KVM modules from sourceforge, I'll be able to see the KVM module version in /var/log/messages when I load the module. But this isn't the case when I load the modules that comes with the kernel - how can I see check the KVM module version of the current kernel? modinfo etc. doesn't give out any information. Thank you in advance... Best Regards Kenni
