Hi, as RHEL 5.4 came out a few days ago I thought I could rebuilt just a few components to get my own 'preview' of kvm on CentOS 5.3 until there is the official CentOS 5.4. A couple of base libraries (e.g. log4cpp, qspice, ...) where really easy to rebuilt from Red Hat's source rpms but I failed to rebuild the kernel using: mock -r epel-5-x86_64 --rebuild kernel-2.6.18-164.el5.src.rpm Using mock on a Fedora 10 build host, this is the error message: + make -s ARCH=x86_64 INSTALL_MOD_PATH=/var/tmp/kernel-2.6.18-164.el5-root modules_install KERNELRELEASE=2.6.18-164.el5 make: *** No rule to make target `modules_install'. Stop. Did anyone succeed in rebuilding the RHEL 5.4 kernel already? fs
