Add support for systemd init service This patch adds support for a systemd init service for libvirtd and libvirt-guests. The libvirtd.service is not written to use socket activation, since we want libvirtd to start on boot so it can do guest auto-start. The libvirt-guests.service is pretty lame, just exec'ing the original init script for now. Ideally we would factor out the functionality, into some shared tool. Instead of ./configure --with-init-script=redhat You can now do ./configure --with-init-script=systemd Or better still: ./configure --with-init-script=systemd+redhat We can also now support install of the upstart init script * configure.ac: Add systemd, and systemd+redhat options to --with-init-script option * daemon/Makefile.am: Install systemd services * daemon/libvirtd.sysconf: Add note about unused env variable with systemd * daemon/libvirtd.service.in: libvirtd systemd service unit * libvirt.spec.in: Add scripts to installing systemd services and migrating from legacy init scripts * tools/Makefile.am: Install systemd services * tools/libvirt-guests.init.sh: Rename to tools/libvirt-guests.init.in * tools/libvirt-guests.service.in: systemd service unit 2011-07-07 13:45:07 +00:00			`# NB we don't use socket activation.

Leave all child processes running when stopping systemd service Currently the libvirt.service unit file for systemd does not specify any kill mode. So systemd kills off every process inside its cgroup. ie all dnsmasq processes, all virtual machines. This obviously not what we want. Set KillMode=process so that it only kills the top level process of libvirtd * daemon/libvirtd.service.in: Add KillMode=process Reported-By: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Daniel P.

daemon: Allow overriding NOFILES ulimit for the daemon as well One of my latest patches (d8db0f9690) created support for setting the limit for the maximum of opened files by qemu user. However, since libvirtd keeps one FD opened per domain (well, for qemu at least) it will likely hit this limit on huge scenarios. 2012-01-12 17:47:30 +00:00			`# Override the maximum number of opened files`
