The QEMU driver runs as non-root too. This is what the qemu:///session URI is used for. Likewise with the UML driver. The existing tests that invoke libvirtd fail quite frequently for me already due to them activating the QEMU / UML drivers. We really need a way to explicitly say what drivers should be allowed by the daemon, overriding what's compiled in. THis could in fact be useful even for production deployment, allowing site admins to guarentee that Xen driver is never used in the daemon even if it is compiled in by default.
So perhaps a couple of config params like
allowed_drivers = [ "qemu", "xen", "test" ] unix_sock_dir = "/var/run/libvirt/"
Not sure how best to hook the first one up to libvirt.so though - the virInitialize/virStateInitize calls always activate all of them, with no easy way to disable.
Sounds good. I'm deferring "allowed_drivers" for now, and preparing a patch to add support for a new configuration parameter unix_sock_dir and also for log_dir The latter is required because otherwise, there's no way for non-root to use a log file other than ~/.libvirt/log, or for root to use a log file other than the default.
