Hi Dan, With your 28-part patch, I was getting a daemon-conf failure in "make check". This fixes it: Unless you tell me otherwise, I will apply most of this right away, (and let you remove the space-before-max_clients in your patch) since no other part of this change conflicts with your series. From: Jim Meyering <meyering(a)redhat.com&gt; Date: Mon, 1 Dec 2008 14:12:44 +0100 Subject: [PATCH] tests: daemon-conf: accommodate new numeric-valued config params: This test would hang when failing to perturb the new numeric (and non-boolean) valued parameters, max_clients, max_workers, min_workers. * tests/daemon-conf: Require that all commented out settings in libvirtd.conf have the same form. Before, two parameters were not being tested, since a space had snuck between the leading "#" and the "param = value" parts. Apply each RHS-value-perturbing transformation separately, not in series. Let VERBOSE=yes turn on debugging. Be more verbose by default, since this is a relatively long-running test. * qemud/libvirtd.conf: Normalize the spacing around each setting that is to be perturbed by tests/daemon-conf. --- qemud/libvirtd.conf | 10 ++++++---- tests/daemon-conf | 32 ++++++++++++++++++++++++++------ 2 files changed, 32 insertions(+), 10 deletions(-) diff --git a/qemud/libvirtd.conf b/qemud/libvirtd.conf index f269766..b0962f2 100644 --- a/qemud/libvirtd.conf +++ b/qemud/libvirtd.conf @@ -1,7 +1,10 @@ # Master libvirt daemon configuration file # # For further information consult http://libvirt.org/format.html - +# +# NOTE: the tests/daemon-conf regression test script requires +# that each "PARAMETER = VALUE" line in this file have the parameter +# name just after a leading "#". ################################################################# # @@ -45,7 +48,7 @@ # Override the default configuration which binds to all network # interfaces.
