https://bugzilla.redhat.com/show_bug.cgi?id=1685151 This reverts commit e4a969092bda5b3b952963fdf6658895165040b7. Now that drivers may call virConnectOpen() on secondary drivers, it doesn't make much sense to have autostart separated from driver initialization callback. In fact, it creates a problem because one driver during its initialization might try to fetch an object from another driver but since the object is yet to be autostarted the fetch fails. This has been observed in reality: qemu driver performs qemuProcessReconnect() during qemu's stateInitialize phase which may call virDomainDiskTranslateSourcePool() which connects to the storage driver to look up the volume. But the storage driver did not autostarted its pools yet therefore volume lookup fails and the domain is killed.
