When the daemon is starting it autostarts all guests marked as autostartable. This is not an ideal solution for autostarting if there's a lot of domains configured so. After autostarting all right away the guests start competing for disk I/O and the boot is prolonged unnecessarily.
This patch adds a config option to disable autostarting to leave it on user scripts that may use mechanisms to reduce load of the host by limiting the number of guests started in parallel.
I sort wonder whether it is better to expose this as a command line argument rather than a config option. It would make life much easier for people who want to have autostart running most of the time, but occassionally want to start libvirtd without it.
I also think command line argument is better than a config option. And if someone wants to permanently disable autostarting, we have service configuration files for this (such as /etc/sysconfig/libvirtd, /etc/conf.d/libvirtd, ...). Jirka
