[libvirt] [PATCH] Pull DBus event code out into common area
by Daniel P. Berrange 12 Apr '12

12 Apr '12

From: "Daniel P. Berrange" <berrange(a)redhat.com> The policy kit and HAL node device drivers both require a DBus connection. The HAL device code further requires that the DBus connection is integrated with the event loop and provides such glue logic itself. The forthcoming FirewallD integration also requires a dbus connection with event loop integration. Thus we need to pull the current event loop glue out of the HAL driver. Thus we create src/util/virdbus.{c,h} files. This contains just one method virDBusGetSystemBus() which obtains a handle to the single shared system bus instance, with event glue automagically setup. NB, I have not actually tested this on a system with HAL or PolicyKit-0 installed, so it may well not compile. Hopefully someone on list has a suitable system where they can test those two. If not, I'll install a VM next week to test it in. --- .gitignore | 6 ++-- configure.ac | 3 +- daemon/Makefile.am | 3 +- daemon/libvirtd.c | 4 --- src/Makefile.am | 3 +- src/rpc/virnetserver.c | 6 ---- src/rpc/virnetserver.h | 4 --- src/util/virdbus.c | 68 ++++++++++++++++++++++------------------------- 8 files changed, 40 insertions(+), 57 deletions(-) diff --git a/.gitignore b/.gitignore index 5aa9c9b..14a21d0 100644 --- a/.gitignore +++ b/.gitignore @@ -48,12 +48,12 @@ /daemon/*_dispatch.h /daemon/libvirt_qemud /daemon/libvirtd -/daemon/libvirtd.init -/daemon/libvirtd.service /daemon/libvirtd*.logrotate /daemon/libvirtd.8 /daemon/libvirtd.8.in +/daemon/libvirtd.init /daemon/libvirtd.pod +/daemon/libvirtd.service /docs/devhelp/libvirt.devhelp /docs/hvsupport.html.in /docs/libvirt-api.xml @@ -118,6 +118,7 @@ /tests/eventtest /tests/hashtest /tests/jsontest +/tests/libvirtdconftest /tests/networkxml2argvtest /tests/nodeinfotest /tests/nwfilterxml2xmltest @@ -150,7 +151,6 @@ /tests/vmx2xmltest /tests/xencapstest /tests/xmconfigtest -/tests/libvirtdconftest /tools/*.[18] /tools/libvirt-guests.init /tools/virsh diff --git a/configure.ac b/configure.ac index 3863119..f49b620 100644 --- a/configure.ac +++ b/configure.ac @@ -1116,9 +1116,8 @@ if test "$with_dbus" = "yes" || test "$with_dbus" = "check" ; then AC_MSG_ERROR([You must install DBus >= $DBUS_REQUIRED to compile libvirt]) fi]) fi -echo ">>>>>>>>>> $with_dbus <<<<<<<<<<<<<<<<<" + if test "$with_dbus" = "yes" ; then -echo ">>>>>>>>>> $with_dbus <<<<<<<<<<<<<<<<<" AC_DEFINE_UNQUOTED([HAVE_DBUS], 1, [enable communication with DBus]) save_LIBS="$LIBS" diff --git a/daemon/Makefile.am b/daemon/Makefile.am index 5d9f5d7..24cce8f 100644 --- a/daemon/Makefile.am +++ b/daemon/Makefile.am @@ -94,7 +94,7 @@ libvirtd_SOURCES = $(DAEMON_SOURCES) #-D_XOPEN_SOURCE=600 -D_XOPEN_SOURCE_EXTENDED=1 -D_POSIX_C_SOURCE=199506L libvirtd_CFLAGS = \ $(LIBXML_CFLAGS) $(GNUTLS_CFLAGS) $(SASL_CFLAGS) \ - $(XDR_CFLAGS) $(POLKIT_CFLAGS) \ + $(XDR_CFLAGS) $(POLKIT_CFLAGS) $(DBUS_CFLAGS) \ $(WARN_CFLAGS) \ $(COVERAGE_CFLAGS) \ -DQEMUD_PID_FILE="\"$(QEMUD_PID_FILE)\"" \ @@ -108,6 +108,7 @@ libvirtd_LDADD = \ $(LIBXML_LIBS) \ $(GNUTLS_LIBS) \ $(SASL_LIBS) \ + $(DBUS_LIBS) \ $(POLKIT_LIBS) if WITH_DTRACE_PROBES diff --git a/daemon/libvirtd.c b/daemon/libvirtd.c index ce931d4..b098f6a 100644 --- a/daemon/libvirtd.c +++ b/daemon/libvirtd.c @@ -812,7 +812,6 @@ int main(int argc, char **argv) { struct daemonConfig *config; bool privileged = geteuid() == 0 ?

[libvirt] [PATCH] qemu, util fix netlink callback registration for migration

[libvirt] [PATCH] qemu_agent: Report error class at least
by Michal Privoznik 12 Apr '12

12 Apr '12

Currently, qemu GA is not providing 'desc' field for errors like we are used to from qemu monitor. Therefore, we fall back to this general 'unknown error' string. However, GA is reporting 'class' which is not perfect, but much more helpful than generic error string. Thus we should fall back to class firstly and if even no class is presented, then we can fall back to that generic string. Before this patch: virsh # dompmsuspend --target mem f16 error: Domain f16 could not be suspended error: internal error unable to execute QEMU command 'guest-suspend-ram': unknown QEMU command error After this patch: virsh # dompmsuspend --target mem f16 error: Domain f16 could not be suspended error: internal error unable to execute QEMU command 'guest-suspend-ram': CommandNotFound --- src/qemu/qemu_agent.c | 14 ++++++-------- 1 files changed, 6 insertions(+), 8 deletions(-) diff --git a/src/qemu/qemu_agent.c b/src/qemu/qemu_agent.c index b759b7f..decfd0e 100644 --- a/src/qemu/qemu_agent.c +++ b/src/qemu/qemu_agent.c @@ -1035,19 +1035,17 @@ static const char * qemuAgentStringifyError(virJSONValuePtr error) { const char *klass = virJSONValueObjectGetString(error, "class"); - const char *detail = NULL; + const char *detail = virJSONValueObjectGetString(error, "desc"); /* The QMP 'desc' field is usually sufficient for our generic - * error reporting needs. + * error reporting needs.

[libvirt] Add USB controller support
by Christophe Fergeau 12 Apr '12

12 Apr '12

Hey, Here is the second version of the patch series implementing USB controller support in libvirt-gconfig. There's a bug fixed in GVirConfigDomainAddressUsb creation (type="usb" was missing) as well as a few small bug fixes/changes in the test program. I also added an additional patch implementing a gvir_config_domain_setup_default_usb_controllers to make adding usb controllers easier following Marc-André's suggestion. Christophe

[libvirt] [test-API PATCH 0/5] Destroy class definition in utils.py
