[libvirt] Is DBus a hard dependency

Hi, currently running libvirtd without DBus fails due to: error : nwfilterDriverStartup:208 : DBus matches could not be installed. Disabling nwfilter driver error : virDBusGetSystemBus:77 : internal error Unable to get DBus system bus connection: Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory error : virStateInitialize:810 : Initialization of NWFilter state driver failed error : daemonRunStateInit:784 : Driver state initialization failed because we fail driver initialization hard in nwfilter_driver.c: if (nwfilterDriverInstallDBusMatches(sysbus) < 0) { VIR_ERROR(_("DBus matches could not be installed. Disabling nwfilter " "driver")); /* * unfortunately this is fatal since virNWFilterTechDriversInit * may have caused the ebiptables driver to use the firewall tool * but now that the watches don't work, we just disable the nwfilter * driver */ goto error; } I wonder if this on prupose or if we can just make this a soft error and go on without DBus? At least in the !HAVE_FIREWALLD case it should be o.k. to continue. Shouldn't it? See attached patch. Cheers, -- Guido
