[libvirt] [PATCH] qemu: Fix escape_monitor(escape_shell(command))
by Philipp Hahn 11 Feb '11

11 Feb '11

Suspending a VM which contains shell meta characters doesn't work with libvirt-0.8.7: /var/log/libvirt/qemu/andreas_231-ne\ doch\ nicht.log: sh: -c: line 0: syntax error near unexpected token `doch' sh: -c: line 0: `cat | { dd bs=4096 seek=1 if=/dev/null && dd bs=1048576; } Although target="andreas_231-ne doch nicht" contains shell meta characters (here: blanks), they are not properly escaped by src/qemu/qemu_monitor_{json,text}.c#qemuMonitor{JSON,Text}MigrateToFile() First, the filename needs to be properly escaped for the shell, than this command line has to be properly escaped for qemu again. For this to work, remove the old qemuMonitorEscapeArg() wrapper, rename qemuMonitorEscape() to it removing the handling for shell=TRUE, and implement a new qemuMonitorEscapeShell() returning strings using single quotes. Using double quotes or escaping special shell characters with backslashes would also be possible, but the set of special characters heavily depends on the concrete shell (dsh, bash, zsh) and its setting (history expansion, interactive use, ...)

[libvirt] [RFC PATCH 0/6] Switch over qemu command line capabilities to virBitmap
by Jiri Denemark 11 Feb '11

11 Feb '11

There are two main reasons behind this patchset: - we are getting very close to 64 flags which is the maximum we can use with unsigned long long - by using LL constants in enum we already violates C99 constraint that enum values have to fit into int This is a very conflict-prone patchset so I'd like to get some feedback on the ideas and naming used so that this could possible be among the first patches pushed after 0.8.8 release. Patches 2/6 and 4/6 are fully and 3/6 mostly mechanical. 5/6 and 6/6 need to be squashed into a single patch but are provided separately for easier review. Jiri Denemark (6): util: Add API for converting virBitmap into printable string qemu: Rename QEMUD_CMD_FLAG_* to QEMU_CAPS_* qemu: Use helper functions for handling cmd line capabilities qemu: Rename qemud\?CmdFlags to qemuCaps qemu: Switch over command line capabilities to virBitmap tests: Use virBitmap for qemu command line caps src/libvirt_private.syms | 1 + src/qemu/qemu_capabilities.c | 238 +++++++++----- src/qemu/qemu_capabilities.h | 150 +++++---- src/qemu/qemu_command.c | 384 +++++++++++----------- src/qemu/qemu_command.h | 30 +- src/qemu/qemu_driver.c | 106 ++++--- src/qemu/qemu_hotplug.c | 162 +++++----- src/qemu/qemu_hotplug.h | 32 +- src/util/bitmap.c | 32 ++- src/util/bitmap.h | 3 + tests/qemuargv2xmltest.c | 2 +- tests/qemuhelptest.c | 745 +++++++++++++++++++++--------------------- tests/qemuxml2argvtest.c | 470 +++++++++++++------------- 13 files changed, 1249 insertions(+), 1106 deletions(-) -- 1.7.4

[libvirt] [PATCH] Imprint all logs with version + package build information
by Daniel P. Berrange 11 Feb '11

11 Feb '11

The logging functions are enhanced so that immediately prior to the first log message being printed to any output channel, the libvirt package version will be printed. eg $ LIBVIRT_DEBUG=1 virsh 18:13:28.013: 17536: info : libvirt version: 0.8.7 18:13:28.013: 17536: debug : virInitialize:361 : register drivers ... The 'configure' script gains two new arguments which can be used as --with-packager="Fedora Project, x86-01.phx2.fedoraproject.org, 01-27-2011-18:00:10" --with-packager-version="1.fc14" to allow distros to append a custom string with package specific data. The RPM specfile is modified so that it appends the RPM version, the build host, the build date and the packager name. eg $ LIBVIRT_DEBUG=1 virsh 18:14:52.086: 17551: info : libvirt version: 0.8.7, package: 1.fc13 (Fedora Project, x86-01.phx2.fedoraproject.org, 01-27-2011-18:00:10) 18:14:52.086: 17551: debug : virInitialize:361 : register drivers Thus when distro packagers receive bug reports they can clearly see what version was in use, even if the bug reporter mistakenly or intentionally lies about version/builds * src/util/logging.c: Output version data prior to first log message * libvirt.spec.in: Include RPM release, date, hostname & packager * configure.ac: Add --with-packager & --with-packager-version args --- configure.ac | 19 +++++++++++ libvirt.spec.in | 9 +++++ src/util/logging.c | 91 +++++++++++++++++++++++++++++++++++++++++++-------- 3 files changed, 104 insertions(+), 15 deletions(-) diff --git a/configure.ac b/configure.ac index 8a4083f..3cd824a 100644 --- a/configure.ac +++ b/configure.ac @@ -29,6 +29,25 @@ AC_SUBST([LIBVIRT_VERSION]) AC_SUBST([LIBVIRT_VERSION_INFO]) AC_SUBST([LIBVIRT_VERSION_NUMBER]) +AC_ARG_WITH([packager], + [AS_HELP_STRING([--with-packager], + [Extra packager name])], + [],[]) +AC_ARG_WITH([packager-version], + [AS_HELP_STRING([--with-packager-version], + [Extra packager version])], + [],[]) +if test "x$with_packager" != "xno" +then + AC_DEFINE_UNQUOTED([PACKAGER], ["$with_packager"], + [Extra package name]) +fi +if test "x$with_packager_version" != "xno" +then + AC_DEFINE_UNQUOTED([PACKAGER_VERSION], ["$with_packager_version"], + [Extra package version]) +fi + dnl Required minimum versions of all libs we depend on LIBXML_REQUIRED="2.6.0" GNUTLS_REQUIRED="1.0.25" diff --git a/libvirt.spec.in b/libvirt.spec.in index 0a2d10e..da1fe4a 100644 --- a/libvirt.spec.in +++ b/libvirt.spec.in @@ -592,6 +592,13 @@ of recent versions of Linux (and other OSes). %define _without_dtrace --without-dtrace %endif +%define when %(date +"%%m-%%d-%%Y-%%H:%%M:%%S") +%define where %(hostname) +%define who %{?packager}%{!?packager:Unknown} +%define with_packager --with-packager="%{who}, %{when}, %{where}" +%define with_packager_version --with-packager-version="%{release}" + + %configure %{?_without_xen} \ %{?_without_qemu} \ %{?_without_openvz} \ @@ -626,6 +633,8 @@ of recent versions of Linux (and other OSes). %{?_without_macvtap} \ %{?_without_audit} \ %{?_without_dtrace} \ + %{with_packager} \ + %{with_packager_version} \ --with-qemu-user=%{qemu_user} \ --with-qemu-group=%{qemu_group} \ --with-init-script=redhat \ diff --git a/src/util/logging.c b/src/util/logging.c index a80c3e3..85406bf 100644 --- a/src/util/logging.c +++ b/src/util/logging.c @@ -108,6 +108,7 @@ static int virLogNbFilters = 0;

[libvirt] consistency of virsh help output
by Zdenek Styblik 11 Feb '11

11 Feb '11

Hello, I've found virsh help output to be inconsistent. ~~~ SNIP ~~~ attach-disk <domain> <source> <target> [--driver <string>]... X attach-interface <domain> <type> <source> [<target>] ... ~~~ SNIP ~~~ where <KEYWORD> is usually explained in OPTIONS as: ~~~ SNIP ~~~ [--domain] <string> domain name, id or uuid ~~~ SNIP ~~~ Substitution of <domain> -> [--domain] <string> resp. that you can only provide a <string> without [--domain] and it's still going to work. This took me some time to figure out. But back on point. As you can see from snips, once you use eg. <domain> and substitution resp. explanation is in OPTIONS and second you put "explanation" right into SYNOPSIS. I think it would be worth of cleaning out and make everything one way or another. Would it be a problem? I presume it's just matter of modifying "couple" printf()-s.

[libvirt] domain.rng updated ?
by arnaud.champion＠devatom.fr 10 Feb '11

10 Feb '11

?Hi, I'm working on C# bindings, my goal is to expose xml descriptions (domain, node, storage and so on...) as real C# objects, for this, I'm studying the rng files provided in /docs/schemas/ directory of the sources. I'm currently working on domain.rng. I don't know if the domain.rng file is up to date because, for example, the disk device definition in the rng doesn't speak about the "address" node that a virhs dumpxml show : <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/var/lib/libvirt/image/Ubuntu-10.10.img'/> <target dev='hda' bus='ide'/> <address type='drive' controller='0' bus='0' unit='0'/> </disk> Is the domain.rng up to date or should I use the libvirt.org XML format page only ? Regards, Arnaud
