[libvirt] [PATCH 0/8] Refactor libvirt RPM to allow fine grained installed

This is an update of the patch DV reverted from GIT https://www.redhat.com/archives/libvir-list/2012-March/msg01332.html At the end of this series we have the following RPMs with files The daemon itself (if %with_libvirtd == 1 - ie skipped for %client_only builds) - libvirt-daemon - just libvirtd daemon & secondary drivers (storage, network, nwfilter, etc) Two optional config file packages (if %with_libvirtd == 1): - libvirt-daemon-config-network - just the network driver default config - libvirt-daemon-config-nwfilter - just the nwfilter default config Four hypervisor driver packages (%with_driver_modules == 1, now on by default) - libvirt-daemon-driver-qemu - libvirt_driver_qemu.so + related driver files - libvirt-daemon-driver-lxc - libvirt_driver_lxc.so + related driver files - libvirt-daemon-driver-uml - libvirt_driver_uml.so + related driver files - libvirt-daemon-driver-xen - libvirt_driver_{xen,libxl}.so + related driver files Other non-daemon packages always enabled - libvirt-client - libvirt.so + virsh - libvirt-devel - libvirt header files & libraries - libvirt-python - libvirt python module - libvirt-docs - API docs and website docs Finally there are a handful of virtual empty packages To preserve the existing upgrade path & avoid breaking existing app dependancies: - libvirt - Depends libvirt-daemon, libvirt-client, libvirt-daemon-config-* and libvirt-daemon-driver-*. To allow applications to depend on specific libvirt drivers: - libvirt-daemon-qemu - Depends on libvirt-daemon, libvirt-daemon-driver-qemu & qemu - libvirt-daemon-kvm - Depends on libvirt-daemon, libvirt-daemon-driver-qemu & qemu-kvm - libvirt-daemon-lxc - Depends on libvirt-daemon, libvirt-daemon-driver-lxc - libvirt-daemon-uml - Depends on libvirt-daemon, libvirt-daemon-driver-uml - libvirt-daemon-xen - Depends on libvirt-daemon, libvirt-daemon-driver-xen & xen The result is: - To install everything (daemon, all drivers, all configs) yum install libvirt - To install just KVM with no configs yum install libvirt-daemon-kvm - To install KVM + default configs yum install libvirt-daemon-kvm libvirt-daemon-config-network libvirt-daemon-config-nwfilter The problems solved are - Can install libvirtd without the default configs which many apps don't want and causing death to networking if installed inside a guest - Applications don't need to know about the underlying hypervisor package names - libvirt pulls in the correct packages - Applications can install KVM without pulling in Xen libraries
