The kernel specified + with --kerneldir refers to kernel B, that is, the kernel for which + the module is built. + +- Building from a cloned git repository (most likely useful for developers + only) requires a kernel tree with the main kvm sources (kernel A) that + is included as a submodule in the linux-2.6/ directory. By default, + the KVM development tree on git.kernel.org is used, but this can be + changed in the git configuration. + + Before the kvm module can be built, the linux submodule must be initialised + and populated. The required sequence of commands is + + git submodule init + git submodule update + ./configure + make sync + make + + Notice that you can also specify an existing Linux tree for the + synchronisation stage by using + + make sync LINUX=/path/to/kernel/A + + LINUX specifies the path to kernel A from which the KVM sources are taken. + The directory must point to a local git tree, not to a plain directory + containing the kernel sources.
