[libvirt] [PATCH] qemu: Use 'idx' instead of 'index' for variable name
by John Ferlan 14 Apr '15

14 Apr '15

Apparently for Xen-devel 'index' is a global and causes a build failure, so just use the shortened 'idx' instead to avoid the conflict. Signed-off-by: John Ferlan <jferlan(a)redhat.com> --- I did try modify cfg.mk to add a syntax check similar to the ii,jj,kk checks, but it tripped up over 'index' declarations inside structures. I'd be happy to add one, but I need some help formatting it...

[libvirt] [PATCH] lib: snapshot: Explain that only one layer of images is inserted
by Peter Krempa 14 Apr '15

14 Apr '15

When creating a snapshot with _REUSE_EXTERNAL when the pre-created image does not directly link to the current active layer libvirt would re-detect the backing chain incorrectly and it would not match with qemu's view.

[libvirt] [PATCH v2 0/9] Implement Add/Del IOThreads
by John Ferlan 14 Apr '15

14 Apr '15

v1: http://www.redhat.com/archives/libvir-list/2015-March/msg01014.html v2 is mostly a completely rewrite of v1 - only smart parts were kept, mostly the "concepts" behind adding/removing a thread Patches 1&2: Couple of simple mods - mostly innocuous Patches 3-5 Since it was determined that just setting the IOThread count and keeping sequential IOThread ID's may not be a desired means to add/remove threads, I decided upon a mechanism which to a degree follows the tune/pin mechanism. Rework the existing IOThread logic to make use of a new domain XML element <iothreadids> which will list each of the <iothread>'s with attributes "id" (required) and "name" (optional). The "id" allows one to generate their own ID number/naming mechanism. If <iothreadids> is not found in the XML, then internally will generate the data structures that support it - IOThreadID's. Work the IOThreadID logic into the "live" iothreadpid lists (or now arrays) to manage the live IOThread data Patches 6-7 Add the API/plumbing for two new API's - virDomainAddIOThread and virDomainDelIOThread to complement the existing virDomainPinIOThread. The "Add" API will take two parameters - an iothread_id and an optional "name". The "Del" API will take just one parameter - the iothread_id Patch 8-9 Implement the qemu backend and virsh front end to manage IOThreads either live or just the config file. I did leave some // comments in Patch 8 as a way to ask a reviewer their thoughts in the add live error path whether 'extra' cleanup should be done or just ignored. Those would be cleaned up and removed for the final version. John Ferlan (9): Rename qemuCheckIothreads to qemuCheckIOThreads Convert virDomainPinIsDuplicate into bool return conf: Add new domain XML element 'iothreadids' qemu: Convert iothreadpids into an array of structures qemu: Use domain iothreadids to populate iothreadpids Implement virDomainAddIOThread and virDomainDelIOThread remote: Add support for AddIOThread and DelIOThread qemu: Add support to Add/Delete IOThreads virsh: Add iothreadadd and iothreaddel commands docs/formatdomain.html.in | 28 ++ docs/schemas/domaincommon.rng | 17 + include/libvirt/libvirt-domain.h | 7 + src/conf/domain_audit.c | 9 + src/conf/domain_audit.h | 6 + src/conf/domain_conf.c | 253 ++++++++++- src/conf/domain_conf.h | 29 +- src/driver-hypervisor.h | 13 + src/libvirt-domain.c | 132 ++++++ src/libvirt_private.syms | 7 + src/libvirt_public.syms | 6 + src/qemu/qemu_cgroup.c | 16 +- src/qemu/qemu_command.c | 108 ++++- src/qemu/qemu_command.h | 4 + src/qemu/qemu_domain.c | 55 ++- src/qemu/qemu_domain.h | 12 +- src/qemu/qemu_driver.c | 467 ++++++++++++++++++++- src/qemu/qemu_process.c | 32 +- src/remote/remote_driver.c | 2 + src/remote/remote_protocol.x | 31 +- src/remote_protocol-structs | 13 + .../qemuxml2argv-iothreads-ids-partial.args | 10 + .../qemuxml2argv-iothreads-ids-partial.xml | 33 ++ .../qemuxml2argv-iothreads-ids.args | 8 + .../qemuxml2argv-iothreads-ids.xml | 33 ++ .../qemuxml2argv-iothreads-name.args | 17 + .../qemuxml2argv-iothreads-name.xml | 44 ++ tests/qemuxml2argvtest.c | 4 + tests/qemuxml2xmltest.c | 3 + tools/virsh-domain.c | 174 ++++++++ tools/virsh.pod | 32 ++ 31 files changed, 1546 insertions(+), 59 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-iothreads-ids-partial.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-iothreads-ids-partial.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-iothreads-ids.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-iothreads-ids.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-iothreads-name.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-iothreads-name.xml -- 2.1.0

I think you would need a new virsh change-media option, e.g. --xml, that takes a <disk> element instead of a source path + target path pair. However, I am not a libvirt developer. Paolo

[libvirt] luajit binding
by William Adams 13 Apr '15

13 Apr '15

Hello List, I am new to libvirt, and this is my first query. I have started a luajit language binding for libvirt. It can be found here: https://github.com/Wiladams/LJIT2Virt I searched the interwebs before I began, but didn't find any existing lua language bindings. Is this true? Did I just miss it? If it doesn't exist already, I'd like to make this a regular thing, and get it listed on the language bindings page. How can I go about that? -- William =============================== - Shaping clay is easier than digging it out of the ground.

[libvirt] An implementation bug in qemuMigrationWaitForCompletion that introduces an unnecessary sleep of 50 ms when a migration completes
by Xing Lin 13 Apr '15

13 Apr '15

Hi, It seems that I found a bug in the qemuMigrationWaitForCompletion(). It will do a sleep of 50 ms, even when qemuMigrationUpdateJobStatus() detects that a migration has completed. Here is the original implementation of the while loop. while (jobInfo->type == VIR_DOMAIN_JOB_UNBOUNDED) { /* Poll every 50ms for progress & to allow cancellation */ struct timespec ts = { .tv_sec = 0, .tv_nsec = 50 * 1000 * 1000ull }; if (qemuMigrationUpdateJobStatus(driver, vm, job, asyncJob) == -1) break; /* cancel migration if disk I/O error is emitted while migrating */ if (abort_on_error && virDomainObjGetState(vm, &pauseReason) == VIR_DOMAIN_PAUSED && pauseReason == VIR_DOMAIN_PAUSED_IOERROR) { virReportError(VIR_ERR_OPERATION_FAILED, _("%s: %s"), job, _("failed due to I/O error")); break; } if (dconn && virConnectIsAlive(dconn) <= 0) { virReportError(VIR_ERR_OPERATION_FAILED, "%s", _("Lost connection to destination host")); break; } virObjectUnlock(vm); nanosleep(&ts, NULL); virObjectLock(vm); } Even when qemuMigrationUpdateJobStatus() detects a migration has completed, the nanosleep() will be called again. When the while condition is checked, then the program breaks from the while loop. This introduces an unnecessary sleep of 50 ms which can be avoided by doing a sleep first. The code should likely be structured as following. while (jobInfo->type == VIR_DOMAIN_JOB_UNBOUNDED) { /* Poll every 50ms for progress & to allow cancellation */ struct timespec ts = { .tv_sec = 0, .tv_nsec = 50 * 1000 * 1000ull }; // do sleep here. virObjectUnlock(vm); nanosleep(&ts, NULL); virObjectLock(vm); if (qemuMigrationUpdateJobStatus(driver, vm, job, asyncJob) == -1) break; /* cancel migration if disk I/O error is emitted while migrating */ if (abort_on_error && virDomainObjGetState(vm, &pauseReason) == VIR_DOMAIN_PAUSED && pauseReason == VIR_DOMAIN_PAUSED_IOERROR) { virReportError(VIR_ERR_OPERATION_FAILED, _("%s: %s"), job, _("failed due to I/O error")); break; } if (dconn && virConnectIsAlive(dconn) <= 0) { virReportError(VIR_ERR_OPERATION_FAILED, "%s", _("Lost connection to destination host")); break; } } I have filed a bug report at redhat bugzilla, with a bug id 1210502. The link is below. https://bugzilla.redhat.com/show_bug.cgi?id=1210502 I also prepared a patch for fixing it. It is attached. Any comments?
