[libvirt] [PATCHv2 0/9] support to set cpu bandwidth for hypervisor threads
by Hu Tao 26 Jun '12

26 Jun '12

Currently, we only can set cpu bandwidth for vcpu. If the hypervisor threads consume too much cpu time, it may affect the vcpu. This patchset allows the user to control the cpu bandwidth for hypervisor threads. Changes: v2: - rename qemuSetupCgroupVcpuBW to qemuSetupCgroupCpuBandwidth - limit cpu bandwidth only for vcpus - update doc about hypervisor_period/hypervisor_quota - add virCgroupMoveTask to libvirt_private.syms Hu Tao (3): rename qemuSetupCgroupVcpuBW to qemuSetupCgroupCpuBandwidth limit cpu bandwidth only for vcpus update doc about hypervisor_period/hypervisor_quota Wen Congyang (6): Introduce the function virCgroupForHypervisor introduce the function virCgroupMoveTask() create a new cgroup and move all hypervisor threads to the new cgroup Update XML Schema for new entries qemu: Implement hypervisor's period and quota tunable XML configuration and parsing qemu: Implement hypervisor_period and hypervisor_quota's modification docs/schemas/domaincommon.rng | 10 ++ include/libvirt/libvirt.h.in | 16 ++++ src/conf/domain_conf.c | 25 +++++- src/conf/domain_conf.h | 2 + src/libvirt_private.syms | 2 + src/qemu/qemu_cgroup.c | 107 ++++++++++++++++------ src/qemu/qemu_cgroup.h | 8 +- src/qemu/qemu_driver.c | 201 +++++++++++++++++++++++++++-------------- src/qemu/qemu_process.c | 4 + src/util/cgroup.c | 96 ++++++++++++++++++++ src/util/cgroup.h | 6 ++ tools/virsh.pod | 11 ++- 12 files changed, 381 insertions(+), 107 deletions(-) -- 1.7.4.4

[libvirt] [PATCH v2] storage backend: Add sheepdog support
by Sebastian Wiedenroth 26 Jun '12

26 Jun '12

This patch brings support to manage sheepdog pools and volumes to libvirt. It uses the "collie" command-line utility that comes with sheepdog for that. A sheepdog pool in libvirt maps to a sheepdog cluster. It needs a host and port to connect to, which in most cases is just going to be the default of localhost on port 7000. A sheepdog volume in libvirt maps to a sheepdog vdi. To create one specify the pool, a name and the capacity. Volumes can also be resized later. In the volume XML the vdi name is prefixed with "sheepdog:" and put into the <target><path>. To use the volume as a disk source for virtual machines specify the vdi name as "name" attribute of the <source>. The host and port information from the pool are specified inside the host tag. <disk type='network'> ... <source protocol="sheepdog" name="vdi_name"> <host name="localhost" port="7000"/> </source> </disk> To work right this patch parses the output of collie, so it relies on the raw output option. There recently was a bug which caused size information to be reported wrong. This is fixed upstream already and will be in the next release.

[libvirt] Potential deadlock in libvirt lxc driver
by Thomas Hunger 25 Jun '12

25 Jun '12

Hi, I'm running version 0.9.10 on debian [1]. When starting and stopping containers I see deadlocks every so often. I attached a full backtrace (see at the end of the log). This seems to happen in conditions similar to the segfault I wrote about recently. I.e. usually when destroying domains. I'm unsure why but it seems to me that lxcMonitorEvent gets called after a vm has been freed. This happens despite lxcVmCleanup calling "virEventRemoveHandle(priv->monitorWatch);" to remove the handle. best, Tom [1] Linux zap 3.1.0-1-amd64 #1 SMP Tue Jan 10 05:01:58 UTC 2012 x86_64 GNU/Linux

[libvirt] [ANNOUNCE] libvirt-glib 0.0.9 release
by Daniel P. Berrange 25 Jun '12

25 Jun '12

I am pleased to announce that a new release of the libvirt-glib package, version 0.0.8 is now available from ftp://libvirt.org/libvirt/glib/ The packages are GPG signed with Key fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R) New in this release: - Full API docs for libvirt-glib library - Add API for getting domain OS config - Add API for getting domain OS boot devices - Add APIs for querying host capabilities - Add missing domain OS type enum values - Add API for getting domain virt type - Add comprehensive API arg checking - Add API for getting domain arch - Allow zero timeouts in timer - Fix build with newer glibc-headers and -O0 - Fix generation of filesystem source element - Port to use Mingw64 toolchain for automated builds - Add async API for starting domains - Fix thread safety of event loop timeouts/watches - Add support for filesystem type=bind|ram libvirt-glib comprises three distinct libraries: - libvirt-glib - Integrate with the GLib event loop and error handling - libvirt-gconfig - Representation of libvirt XML documents as GObjects - libvirt-gobject - Mapping of libvirt APIs into the GObject type system NB: While libvirt aims to be API/ABI stable forever, with libvirt-glib we are not yet guaranteeing that libvirt-glib libraries are API/ABI permanently stable. As of the 0.0.8 release, we have tentatively frozen the API/ABI with the intent of being longterm stable hereafter, but there is still a small chance we might find flaws requiring an API/ABI change. The likelihood of this is low, however, and we will strive to avoid it. Follow up comments about libvirt-glib should be directed to the regular libvir-list redhat com development list. Thanks to all the people involved in contributing to this release.

[libvirt] [PATCH] storage backend rbd: Do not prefix rbd: on volume names.
by Wido den Hollander 25 Jun '12

25 Jun '12

We used to prefix 'rbd:' to volume names, this is not necessary. Qemu takes RBD devices in this way, like: qemu -drive rbd:pool/image When attaching a network disk like RBD to a guest we however do not use this prefix. Currently you can't map a RBD volume name directly to a domain without removing the prefix.

[libvirt] [PATCH 1/2] storage: Switch to new def on pool-destroy
by Michal Privoznik 25 Jun '12

25 Jun '12

Currently, we share the idea of old & new def with domains. Users can *-edit an object (domain, pool) which spawns a new internal representation for them. This is referenced via {domainObj,poolObj}->newDef [compared to ->def]. However, for pool we were never overwriting def with newDef. This must be done on pool-destroy (like we do analogically in domain detroy). --- src/storage/storage_driver.c | 5 ++++- 1 files changed, 4 insertions(+), 1 deletions(-) diff --git a/src/storage/storage_driver.c b/src/storage/storage_driver.c index 88f3809..3b95c70 100644 --- a/src/storage/storage_driver.c +++ b/src/storage/storage_driver.c @@ -794,6 +794,10 @@ storagePoolDestroy(virStoragePoolPtr obj) { if (pool->configFile == NULL) { virStoragePoolObjRemove(&driver->pools, pool); pool = NULL; + } else if (pool->newDef) { + virStoragePoolDefFree(pool->def); + pool->def = pool->newDef; + pool->newDef = NULL; } ret = 0; @@ -804,7 +808,6 @@ cleanup: return ret; } - static int storagePoolDelete(virStoragePoolPtr obj, unsigned int flags) { -- 1.7.8.5

[libvirt] This patch creates a mount point for libvirt-lxc containers to mount on the destination system if it does not exist.
by Daniel J Walsh 25 Jun '12

25 Jun '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Currently libvirt-lxc checks to see if the destination exists and is a directory. If it is not a directory then the mount fails. Since libvirt-lxc can bind mount files on an inode, this patch is needed to allow us to bind mount files on files. Currently we want to bind mount on top of /etc/machine-id, and /etc/adjtime If the destination of the mount point does not exists, it checks if the src is a directory and then attempts to create a directory, otherwise it creates an empty file for the destination. The code will then bind mount over the destination. Current code blows up if the destination was not a directory. We want to be able to bind mount files on files. Sorry if you are seeing this patch for the second time, since I sent it to the wrong list. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk/kel4ACgkQrlYvE4MpobP7uwCfXUPMJP4bNZiBGTwnJ70dezVf KPwAnjt3MYSlHxkcwZCe5H1X4C0P4ky/ =1te/ -----END PGP SIGNATURE-----
