Is there any way we can avoid having to start/stop libvirtd for this testing ? The general goal of the TCK is that it is testing an existing deployment, so it should be expecting that libvirtd is already up & running in a desired configuration. If we have to stop/start libvirtd, then the test script using these APIs will need to be protected to make sure it only runs when used with 'qemu:///system' or 'lxc://'. ie is skipped with qemu:///session or vmware, or virtualbox, etc

Little perl black magic tip for you.... If you want to read the entire file contents into a single string, then you can do open LOG, "<$log_name"; local $/ = undef; my $actual_log = <LOG>; close LOG; '$/' is the line separator. By setting it to 'undef' we tell Perl that there is no line separator, so it will immediately read until end of file :-) BTW see 'man perlvar' for this particular example Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://deltacloud.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|
