I am building kvm as an external module against 2.6.38-8 (Ubuntu 11.04 kernel). The kvm.ko and kvm-intel.ko build and insmod without any issues. However I am able to unload the kvm-intel module. Here is the lsmod listing: kvm_intel 135653 0 [permanent] kvm 381130 1 kvm_intel,[permanent] This is the error I get when I try to unload the module: ERROR: Removing 'kvm_intel': Device or resource busy Do I need to do anything special during building for CONFIG_MODULE_UNLOAD to take effect? PS: I am able to rmmod the kvm module that is packages with the Ubuntu 11.04 kernel.
