This libvirt feature will probably come in handy to others and so I want to share it. The "-nodefconfig" option will prevent QEMU from loading any of those config files.-no-user-config The "-no-user-config" option makes QEMU not load any of the user-provided config files on sysconfdir, but won't make it skip the QEMU-provided config files from datadir.-trace [events=file][,file=file] Specify tracing options.
