[libvirt] [PATCH] lxc: return correct number of CPUs
by Martin Kletzander 30 May '12

30 May '12

When getting number of CPUs the host has assigned, there was always number "1" returned. Even though all lxc domains with no pinning launched by libvirt run on all pCPUs (by default, no matter what's the number), we should at least return the same number as the user specified when creating the domain. --- The bug addressed above will be managed later, because I believe this needs to be discussed first (we don't say that <vcpu> is not supported for lxc, but we are able to set only pinning, shares, not number of CPUs; due to using cgroups). The question will be: "Should we change the docs and ban it in the code or make some workaround for fixing it?" src/lxc/lxc_driver.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/lxc/lxc_driver.c b/src/lxc/lxc_driver.c index 9aea556..33b2774 100644 --- a/src/lxc/lxc_driver.c +++ b/src/lxc/lxc_driver.c @@ -590,7 +590,7 @@ static int lxcDomainGetInfo(virDomainPtr dom, } info->maxMem = vm->def->mem.max_balloon; - info->nrVirtCpu = 1; + info->nrVirtCpu = vm->def->vcpus; ret = 0; cleanup: -- 1.7.8.6

[libvirt] serial console/events example script
by Dave Allan 30 May '12

30 May '12

Hi all, A while back I wrote the attached code to demonstrate how to use events and serial console to create a serial console that stays up even when the VM is down. Is it worth adding to the examples? It might need some work, as I am not terribly strong with Python. Dave

[libvirt] [PATCH] build: don't lose probes.o files
by Eric Blake 29 May '12

29 May '12

The previous patch fixed an incremental build, but missed that on a fresh checkout, we now have nothing requiring that stops make from nuking libvirt_qemu_probes.o. * src/Makefile.am ($(libvirt_driver_qemu_la_SOURCES)): Delete, since this variable is empty. (.PRECIOUS): Add %_probes.o, so they don't get nuked as an intermediate by-product after creating %_probes.lo. --- Pushing under the build-breaker rule; this time I've done more testing, including ./autobuild.sh on a fresh checkout (that died later on, due to the augeas issue mentioned here[1], but at least it got past the probes.o hangup).

[libvirt] [PATCH] build: fix testing of augeas files in VPATH builds
by Eric Blake 29 May '12

29 May '12

Without this fix, a VPATH build fails with messages like: make[3]: Entering directory `/home/remote/eblake/libvirt-tmp2/build/daemon' ../../build-aux/augeas-gentest.pl libvirtd.conf ../../daemon/test_libvirtd.aug.in test_libvirtd.aug cannot read libvirtd.conf: No such file or directory at ../../build-aux/augeas-gentest.pl line 38. * daemon/Makefile.am (AUG_GENTEST): Factor out definition. (test_libvirtd.aug): Look for correct file. * src/Makefile.am (AUG_GENTEST): Use $(PERL). (qemu/test_libvirtd_qemu.aug, lxc/test_libvirtd_lxc.aug) (locking/test_libvirt_sanlock.aug): Ensure destination dir exists. --- This is one alternative for a fix for a build-breaker, but I'm not pushing it without a review. In particular, I still have a question: Should the various test_*.aug files be in the tarball? Right now, they are listed under EXTRA_DIST (so they are shipped pre-built), but also listed under CLEANFILES (so 'make clean' must regenerate them). Generating the files requires perl, which is a non-standard requirement. Either we require end-users to have perl in order to build from a libvirt tarball, and change the tarball to exclude files that perl can generate; or we fix the use of CLEANFILES to instead be DISTCLEANFILES or even MAINTAINERCLEANFILES (end users need not have perl if they don't alter any sources, but we should then be generating the files into $(srcdir) rather than into the build tree). For another example of a perl-generated file, remote_protocol.h is currently shipped in the tarball, and requires perl for generation, but it is generated into the $(srcdir) and only cleaned by MAINTAINERCLEANFILES. daemon/Makefile.am | 6 ++++-- src/Makefile.am | 20 +++++++++++++------- 2 files changed, 17 insertions(+), 9 deletions(-) diff --git a/daemon/Makefile.am b/daemon/Makefile.am index daf24ea..8dd019d 100644 --- a/daemon/Makefile.am +++ b/daemon/Makefile.am @@ -351,8 +351,10 @@ libvirtd.service: libvirtd.service.in $(top_builddir)/config.status check-local: check-augeas -test_libvirtd.aug: test_libvirtd.aug.in libvirtd.conf - $(AM_V_GEN)$(PERL) $(top_srcdir)/build-aux/augeas-gentest.pl libvirtd.conf $< $@ +AUG_GENTEST = $(PERL) $(top_srcdir)/build-aux/augeas-gentest.pl + +test_libvirtd.aug: test_libvirtd.aug.in $(srcdir)/libvirtd.conf + $(AM_V_GEN)$(AUG_GENTEST) $(srcdir)/libvirtd.conf $< $@ check-augeas: test_libvirtd.aug $(AM_V_GEN)if test -x '$(AUGPARSE)'; then \ diff --git a/src/Makefile.am b/src/Makefile.am index 533e78a..0bbccb2 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -1119,11 +1119,13 @@ check-local: check-augeas check-augeas: check-augeas-qemu check-augeas-lxc check-augeas-sanlock -AUG_GENTEST = $(top_srcdir)/build-aux/augeas-gentest.pl +AUG_GENTEST = $(PERL) $(top_srcdir)/build-aux/augeas-gentest.pl if WITH_QEMU -qemu/test_libvirtd_qemu.aug: qemu/test_libvirtd_qemu.aug.in qemu/qemu.conf $(AUG_GENTEST) - $(AM_V_GEN)$(AUG_GENTEST) qemu/qemu.conf $< $@ +qemu/test_libvirtd_qemu.aug: qemu/test_libvirtd_qemu.aug.in \ + $(srcdir)/qemu/qemu.conf $(AUG_GENTEST) + $(AM_V_GEN)$(MKDIR_P) qemu && \ + $(AUG_GENTEST) $(srcdir)/qemu/qemu.conf $< $@ check-augeas-qemu: qemu/test_libvirtd_qemu.aug $(AM_V_GEN)if test -x '$(AUGPARSE)'; then \ @@ -1135,8 +1137,10 @@ check-augeas-qemu: endif if WITH_LXC -lxc/test_libvirtd_lxc.aug: lxc/test_libvirtd_lxc.aug.in lxc/lxc.conf $(AUG_GENTEST) - $(AM_V_GEN)$(AUG_GENTEST) lxc/lxc.conf $< $@ +lxc/test_libvirtd_lxc.aug: lxc/test_libvirtd_lxc.aug.in \ + $(srcdir)/lxc/lxc.conf $(AUG_GENTEST) + $(AM_V_GEN)$(MKDIR_P) lxc && \ + $(AUG_GENTEST) $(srcdir)/lxc/lxc.conf $< $@ check-augeas-lxc: lxc/test_libvirtd_lxc.aug $(AM_V_GEN)if test -x '$(AUGPARSE)'; then \ @@ -1147,8 +1151,10 @@ else check-augeas-lxc: endif -locking/test_libvirt_sanlock.aug: locking/test_libvirt_sanlock.aug.in locking/qemu-sanlock.conf $(AUG_GENTEST) - $(AM_V_GEN)$(AUG_GENTEST) locking/qemu-sanlock.conf $< $@ +locking/test_libvirt_sanlock.aug: locking/test_libvirt_sanlock.aug.in \ + locking/qemu-sanlock.conf $(AUG_GENTEST) + $(AM_V_GEN)$(MKDIR_P) locking && \ + $(AUG_GENTEST) locking/qemu-sanlock.conf $< $@ check-augeas-sanlock: locking/test_libvirt_sanlock.aug $(AM_V_GEN)if test -x '$(AUGPARSE)'; then \ -- 1.7.7.6

[libvirt] [PATCH] virsh: avoid strncpy
by Eric Blake 29 May '12

strncpy is generally evil - it runs the risk of missing NUL termination, and more often than not wastes time zeroing way more bytes than strictly necessary.

[libvirt] Error when running "virsh version" and "virt-manager"
by Shradha Shah 29 May '12

29 May '12

Hello all, I have pulled the latest changes from the upstream libvirt repo as of today morning. I have then self-built and installed libvirt using the following commands (machine OS RHEL6.2): 1) ./autogen.sh --system --enable-compile-warnings=error 2) make 3) make install 4) service libvirtd restart At this point when I run the command "virsh version" I see the following output: Compiled against library: libvir 0.9.12 Using library: libvir 0.9.12 Using API: QEMU 0.9.12 error: failed to get the hypervisor version error: internal error Cannot find suitable emulator for x86_64 Some debug commands and their output: [root@c6100o libvirt]# rpm -qa | grep qemu-kvm qemu-kvm-0.12.1.2-2.209.el6.x86_64 [root@c6100o libvirt]# whereis qemu-kvm qemu-kvm: /usr/libexec/qemu-kvm /usr/share/qemu-kvm /usr/share/man/man1/qemu-kvm.1.gz [root@c6100o libvirt]# which virsh /usr/bin/virsh [root@c6100o libvirt]# which libvirtd /usr/sbin/libvirtd Please may I ask for help in order to resolve this issue? -- Many Thanks, Regards, Shradha Shah

[libvirt] [PATCH] build: silence libtool during tests
by Eric Blake 28 May '12

28 May '12

Libtool is picky about linking against a module library (aka a .so); giving lots of warnings like this in the tests directory: CCLD networkxml2argvtest *** Warning: Linking the executable networkxml2argvtest against the loadable module *** libvirt_driver_network.so is not portable! Fix that by splitting things into a convenience library which can be used directly by the tests, and making the real .so just wrap the convenience library. Based on a suggestion by Daniel P. Berrange. * configure.ac (--with-driver-modules): Fix help test. * src/Makefile.am (libvirt_driver_xen.la, libvirt_driver_libxl.la) (libvirt_driver_qemu.la, libvirt_driver_lxc.la) (libvirt_driver_uml.la): Factor into new convenience libraries. * tests/Makefile.am (xen_LDADDS, qemu_LDADDS, lxc_LDADDS) (networkxml2argvtest_LDADD): Link to convenience libraries, not shared libraries. --- configure.ac | 3 +- src/Makefile.am | 110 +++++++++++++++++++++++++++++----------------------- tests/Makefile.am | 12 +++--- 3 files changed, 69 insertions(+), 56 deletions(-) diff --git a/configure.ac b/configure.ac index 5d06b47..27997ed 100644 --- a/configure.ac +++ b/configure.ac @@ -2420,7 +2420,8 @@ AM_CONDITIONAL([WITH_WIN_ICON], [test "$WINDRES" != ""]) dnl Driver-Modules library AC_ARG_WITH([driver-modules], - AC_HELP_STRING([--with-driver-modules], [build drivers as loadable modules @<:@default=no@:>@]), + AC_HELP_STRING([--with-driver-modules], + [build drivers as loadable modules @<:@default=check@:>@]), [], [with_driver_modules=check]) diff --git a/src/Makefile.am b/src/Makefile.am index 0b20f1f..53c246d 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -662,25 +662,27 @@ endif WITH_REMOTE $< $@ if WITH_XEN +noinst_LTLIBRARIES += libvirt_driver_xen_impl.la +libvirt_driver_xen_la_SOURCES = +libvirt_driver_xen_la_LIBADD = libvirt_driver_xen_impl.la if WITH_DRIVER_MODULES mod_LTLIBRARIES += libvirt_driver_xen.la +libvirt_driver_xen_la_LIBADD += ../gnulib/lib/libgnu.la +libvirt_driver_xen_la_LDFLAGS = -module -avoid-version else noinst_LTLIBRARIES += libvirt_driver_xen.la #
