[libvirt] [PATCHv6 0/6] Add virNodeGetCPUStats() API
by Minoru Usui 02 Jun '11

02 Jun '11

Hi, This is v6 of virNodeGetCPUTimeParameters() API. (This time, I rename it to virNodeGetCPUStats()) It returns cpu utilization or cumulative cpu time of the node from /proc/stat since node boots up. This patch only supports linux host. Changes v5->v6 - Rename API name to virNodeGetCPUStats() - virsh nodecpustats subcommand returns raw/absolute cputime value by default, and add --percent option for printing utilization. v4->v5 - Rebase latest libvirt GIT tree. v3->v4 - Rebase this patch like virDomainGetMemoryParameters() from v2 patches. (drop v3 patches except virsh subcommand) - Rename API name to virNodeGetCPUTimeParameters() v2->v3 - Change user I/F. It is able to request what the user want by the @flags. - Minor change of virsh nodecputime I/F. v1->v2 - Change user I/F like virDomainGetMemoryStats() - It can return either cpu utilization or cumulative cpu time of the node depends on each driver.

[libvirt] [PATCH] security: plug regression introduced in disk probe logic
by Eric Blake 02 Jun '11

02 Jun '11

Regression introduced in commit d6623003 (v0.8.8) - using the wrong sizeof operand meant that security manager private data was overlaying the allowDiskFOrmatProbing member of struct _virSecurityManager.

[libvirt] RFC: Add virDomainBlockPull API family to libvirt
by Adam Litke 01 Jun '11

01 Jun '11

To help speed the provisioning process for large domains, new QED disks are created with backing to a template image. These disks are configured with copy on read such that blocks that are read from the backing file are copied to the new disk. This reduces I/O over a potentially costly path to the backing image. In such a configuration, there is a desire to remove the dependency on the backing image as the domain runs. To accomplish this, qemu will provide an interface to perform sequential copy on read operations during normal VM operation. Once all data has been copied, the disk image's link to the backing file is removed. The virDomainBlockPull API family brings this functionality to libvirt. virDomainBlockPullAll() instructs the hypervisor to stream the entire device in the background. Progress of this operation can be checked with the function virDomainBlockPullInfo(). An ongoing stream can be cancelled with virDomainBlockPullAbort(). If a more controlled IO rate is desired, virDomainBlockPull() can be used to perform a single increment of IO. Subsequent calls to this function will automatically stream the appropriate next increment until the disk has been fully populated. An event (VIR_DOMAIN_EVENT_ID_BLOCK_PULL) will be emitted when a disk has been fully populated or if a BlockPullAll() operation was terminated due to an error. This event is useful to avoid polling on virDomainBlockPullInfo() for completion and could also be used by the security driver to revoke access to the backing file when it is no longer needed. Note: I am sending this series out now (even though image streaming is not quite committed to qemu upstream) because I want to start the review process. At this stage, I expect only minor changes to the qemu implementation. make check: PASS make syntax-check: PASS make -C tests valgrind: PASS I am testing this API with Python Unittest (see the last patch).

[libvirt] remote generator: Legacy support for hyper to long mappings
by Matthias Bolte 01 Jun '11

01 Jun '11

This can be considered as a v2 for hyper annotation patch [1]. Dan argued that hyper-to-long mapping is considered as legacy and hyper should be mapped to long long for all new APIs. Therefore, he voted against the longlong annotation, because this should be the default anyway. I removed the longlong annotations from the original patch. This results in version-A of the attached patch 0001. But this optional annotation makes the parser more complex. One of the reasons for annotating things in the .x is to have single place to define a new procedure. But as the long/longlong annotation only affect exiting procedures and will not be added to new ones it's much simpler to store this information in the generator itself. This information it is fixed and will not change anymore. This is implemented in version-B of the attached patch 0001. I favor version-B, what's your opinion on this? Attached patch 0002 extends the apibuild script to allow the usage of long for the same fixed set as in the remote generator only. It reports an error when new functions or structs use long instead of longlong. [1] https://www.redhat.com/archives/libvir-list/2011-May/msg01434.html Matthias
