[libvirt] [sandbox][PATCH] Add module directory prefix selection feature
by Radu Caragea 20 Jun '12

20 Jun '12

Add module directory prefix selection feature This is useful when running as a non-privileged user if we want to boot a custom compiled kernel: we might not have rights to install in /lib/modules/<kernel release> so when compiling the kernel we can use "make modules_install INSTALL_MOD_PATH=/path" which installs in /path/lib/modules/<kernel release>. By setting with gvir_sandbox_config_set_moddirprefix(cfg, "/path") we can now achieve just that.

[libvirt] NEED HELP on libvirt guest resource control
by Zhimou Peng 20 Jun '12

20 Jun '12

Hi all, I'm from libvirt Section 3 I'm tracking "guest resource control" test from kvm, and i found kvm support more than libvirt. they support these: https://riddler.bne.redhat.com/IEEE_Test_Plans/en-US/RHEL/6.3/html-single/K… guest blkio bandwidth and blkio throttle limitation, guest memory limitation, migrate guest from one memory to another, guest CPU bandwidth limitation, guest freezing, pin guest to certain host CPU, guest net limitation. I want to know what the current libvirt support status and if libvirt will support all these feature in the future? BR zhpeng

[libvirt] [PATCH] conf: Format numatune XML correctly while placement is none
by Osier Yang 20 Jun '12

20 Jun '12

setNumaParameters tunes the numa setting using cgroup, it's another entry except libnuma/numad for numa tuning. And it doesn't set the placement, and further more, the formating codes doesn't take this into consideration. How to reproduce: conn = libvirt.open(None) dom = conn.lookupByName('linux') param = {'numa_nodeset': '0', 'numa_mode': 1} dom.setNumaParameters(param, 2) % virsh start linux error: Failed to start domain rhel6.3rc error: (domain_definition):8: error parsing attribute name <memory mode='preferred' </numatune> -------------------------------^ --- By the way, I see problems of setNumaParameters too. conn = libvirt.open(None) dom = conn.lookupByName('linux') param = {'numa_mode': 1} dom.setNumaParameters(param, 2) The numa 'mode' will be just ignored, and no 'numatune' XML is formated, as neither 'nodeset' nor 'placement' is specified. I'd think it's right to ignore it when formating, it's meaningless to only specify the 'mode'. However, we might have to fix setNumaParameters to prevent setting the numa mode without nodeset, and error out, as it's really a bad user experience to see the API call succeeded, but the expected XML doesn't show up in the end. --- src/conf/domain_conf.c | 17 ++++++++++------- 1 files changed, 10 insertions(+), 7 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 81c6308..c44d89d 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -12795,23 +12795,26 @@ virDomainDefFormatInternal(virDomainDefPtr def, const char *placement; mode = virDomainNumatuneMemModeTypeToString(def->numatune.memory.mode); - virBufferAsprintf(buf, " <memory mode='%s' ", mode); + virBufferAsprintf(buf, " <memory mode='%s'", mode); - if (def->numatune.memory.placement_mode == - VIR_DOMAIN_NUMATUNE_MEM_PLACEMENT_MODE_STATIC) { + if (def->numatune.memory.nodemask) { nodemask = virDomainCpuSetFormat(def->numatune.memory.nodemask, - VIR_DOMAIN_CPUMASK_LEN); + VIR_DOMAIN_CPUMASK_LEN); if (nodemask == NULL) { virDomainReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("failed to format nodeset for " "NUMA memory tuning")); goto cleanup; } - virBufferAsprintf(buf, "nodeset='%s'/>\n", nodemask); + virBufferAsprintf(buf, " nodeset='%s'/>\n", nodemask); VIR_FREE(nodemask); - } else if (def->numatune.memory.placement_mode) { + } else if (def->numatune.memory.placement_mode == + VIR_DOMAIN_NUMATUNE_MEM_PLACEMENT_MODE_AUTO) { placement = virDomainNumatuneMemPlacementModeTypeToString(def->numatune.memory.placement_mode); - virBufferAsprintf(buf, "placement='%s'/>\n", placement); + virBufferAsprintf(buf, " placement='%s'/>\n", placement); + } else { + /* Should not hit here. */ + virBufferAddLit(buf, "/>\n"); } virBufferAddLit(buf, " </numatune>\n"); } -- 1.7.7.3

[libvirt] [PATCHv2 00/13] list all snapshots
by Eric Blake 20 Jun '12

This is a v2 of the remaining patches in: https://www.redhat.com/archives/libvir-list/2012-June/msg00273.html https://www.redhat.com/archives/libvir-list/2012-June/msg00284.html It assumes that Peter's list all domain patches have been applied already, at least through patch 6/12: https://www.redhat.com/archives/libvir-list/2012-June/msg00316.html In other words, this series will not apply to current libvirt.git at the time of this mail. And since I developed against v3 of Peter's patches and he has some tweaks to make, I will probably have to make minor tweaks to rebase on top of his eventual v4. I will follow up with a link to a git repo with Peter's v3 and my series, and/or my rebase on top of his v4. Overall changes since v1: actually tested this time address review comments lots of bug fixes due to corner case testing rearrange the patch series so that metaroot comes before filtering pick up some good ideas from Peter's v3 More details in some of the individual patches, if I can remember everything I did. In particular, I'm quite pleased that the overall diffstat for domain_conf.c reduced in size in spite of adding features :) Eric Blake (13): snapshot: new virsh function factored from snapshot-list snapshot: use new virsh function for snapshot-list snapshot: use metaroot node to simplify management snapshot: merge domain and snapshot computation snapshot: merge count and name collectoin snapshot: add additional filters when getting lists snapshot: expose new flags in virsh list: add virDomainListAllSnapshots API list: use the new snapshot API in virsh when possible list: provide python bindings for snapshots list: provide RPC call for snapshots list: new helper function to collect snapshots list: add qemu snapshot list support daemon/remote.c | 126 ++++++ include/libvirt/libvirt.h.in | 35 +- python/Makefile.am | 2 + python/generator.py | 2 + python/libvirt-override-api.xml | 16 +- python/libvirt-override-virDomain.py | 11 + python/libvirt-override-virDomainSnapshot.py | 11 + python/libvirt-override.c | 92 +++++ src/conf/domain_conf.c | 250 ++++------- src/conf/domain_conf.h | 19 +- src/conf/virdomainlist.c | 44 +- src/conf/virdomainlist.h | 18 + src/driver.h | 12 + src/libvirt.c | 275 +++++++++++-- src/libvirt_private.syms | 3 +- src/libvirt_public.syms | 2 + src/qemu/qemu_driver.c | 137 +++++-- src/qemu/qemu_migration.c | 3 +- src/remote/remote_driver.c | 126 ++++++ src/remote/remote_protocol.x | 26 +- src/remote_protocol-structs | 26 ++ tools/virsh.c | 570 +++++++++++++++++--------- tools/virsh.pod | 14 +- 23 files changed, 1371 insertions(+), 449 deletions(-) create mode 100644 python/libvirt-override-virDomain.py create mode 100644 python/libvirt-override-virDomainSnapshot.py -- 1.7.10.2
