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
