[libvirt] [PATCH v2] 802.1Qbg: use pre-associate state at beginning of incoming migration
by Stefan Berger 30 Nov '10

30 Nov '10

-v2: - changing the vmOpStr array and vmOperation enum to use VIR_ENUM_IMPL and VIR_ENUM_DECL. Renaming the enum to virVMOperationType and adapting the name of the enum constants. This patch introduces the usage of the pre-associate state of the IEEE 802.1Qbg standard on incoming VM migration on the target host. It is in response to bugzilla entry 632750. https://bugzilla.redhat.com/show_bug.cgi?id=632750 For being able to differentiate the exact reason as to why a macvtap device is being created, either due to a VM creation or an incoming VM migration, I needed to pass that reason as a parameter from wherever qemudStartVMDaemon is being called in order to determine whether to send an ASSOCIATE (VM creation) or a PRE-ASSOCIATE (incoming VM migration) towards lldpad. I am also fixing a problem with the virsh domainxml-to-native call on the way. Gerhard successfully tested the patch with a recent blade network 802.1Qbg-compliant switch. The patch should not have any side-effects on the 802.1Qbh support in libvirt, but Roopa (cc'ed) may want to verify this.

[libvirt] [PATCH] OpenVZ: take veid from vmdef->name when defining new domains
by Guido Günther 30 Nov '10

30 Nov '10

Hi, We currently use the next free veid although there's one given in the domain xml. This currently breaks defining new domains since vmdef->name and veid don't match leading to the following error later on: error: Failed to define domain from 110.xml error: internal error Could not set UUID Since silently ignoring vmdef->name is not nice respect it instead. We avoid veid collisions in the upper levels already. O.k. to apply? -- Guido

[libvirt] [PATCH] Log client errors in libvirtd at debug priority

This reverts commit Log all errors at level INFO to stop polluting syslog 04bd0360f32ec628ecf7943b3fd1468d6eb2dde5. and makes virRaiseErrorFull() log errors at debug priority when called from inside libvirtd. This stops libvirtd from polluting it's own log with client errors at error priority that'll be reported and logged on the client side anyway. --- This is basically a v2 for https://www.redhat.com/archives/libvir-list/2010-November/msg01060.html v2 logs client error at debug priority in libvirtd instead of not logging them at all.

Hi Eric, Just ran ./autogen.sh on an OSX box with only the system provided autotools installed, and got this: ************************************************************************************ Copying file po/remove-potcdate.sin ./bootstrap: patching m4/gettext.m4 to remove need for intl/* ... ./bootstrap: glibtoolize -c -f ... glibtoolize: putting auxiliary files in AC_CONFIG_AUX_DIR, `build-aux'. glibtoolize: copying file `build-aux/ltmain.sh' glibtoolize: putting macros in AC_CONFIG_MACRO_DIR, `m4'. glibtoolize: copying file `m4/libtool.m4' glibtoolize: copying file `m4/ltoptions.m4' glibtoolize: copying file `m4/ltsugar.m4' glibtoolize: copying file `m4/ltversion.m4' glibtoolize: copying file `m4/lt~obsolete.m4' ./bootstrap: aclocal -I gnulib/m4 --force -I m4 ... configure.ac:13: warning: macro `AM_SILENT_RULES' not found in library ./bootstrap: autoconf --force ... configure.ac:60: error: possibly undefined macro: AC_MSG_ERROR If this token and others are legitimate, please use m4_pattern_allow.

The problem was easy enough to resolve by installing the newer autoconf and automake MacPorts provides. But, I'm concerned about the less-than-helpful error message given here. Isn't the bootstrap supposed to detect the required versions of things (as specified in the .conf file), and inform us clearly if they're not found? Regards and best wishes, Justin Clift

[libvirt] [PATCH] correct the arguments of migrate_speed
by Wen Congyang 29 Nov '10

29 Nov '10

When we set migrate_speed by json, we receive the following error message: libvirtError: internal error unable to execute QEMU command 'migrate_set_speed': Invalid parameter type, expected: number The reason is that: the arguments of migrate_set_speed by json is json number, not json string.

[libvirt] [PATCH v2 0/5] Support of auto-dump on watchdog event in libvirtd
by Hu Tao 29 Nov '10

29 Nov '10

This patch series adds a new watchdog action `dump' which lets libvirtd can do auto-dump when receiving a watchdog event from qemu guest. In order to make the function work, there must be a watchdog device added to guest, and guest must have a watchdog daemon running, for example, /etc/init.d/watchdog start or auto-started on boot. Hu Tao (5): Add a threadpool implementation Fall back to QEMUD_SAVE_FORMAT_RAW if compression method fails. Add a new function doCoreDump Add a watchdog action `dump' I am one of the authors AUTHORS | 1 + src/Makefile.am | 3 +- src/conf/domain_conf.c | 1 + src/conf/domain_conf.h | 1 + src/qemu/qemu.conf | 5 + src/qemu/qemu_conf.c | 13 +++- src/qemu/qemu_conf.h | 4 + src/qemu/qemu_driver.c | 229 +++++++++++++++++++++++++++++++++--------------- src/util/threadpool.c | 140 +++++++++++++++++++++++++++++ src/util/threadpool.h | 35 ++++++++ 10 files changed, 361 insertions(+), 71 deletions(-) create mode 100644 src/util/threadpool.c create mode 100644 src/util/threadpool.h -- 1.7.3 -- Thanks, Hu Tao
