[libvirt] [PATCH] qemu: domain I/O asynchronous handling
by Michal Privoznik 15 Jun '11

15 Jun '11

For virtio disks and interfaces, qemu allows users to enable or disable ioeventfd feature. This means, qemu can execute domain code, while another thread waits for I/O event. Basically, in some cases it is win, in some loss. This feature is available via 'asyncio' attribute in disk and interface <driver> element. It accepts 'on' and 'off'. Leaving this attribute out defaults to hypervisor decision. --- this is rework as suggested: https://www.redhat.com/archives/libvir-list/2011-May/msg01269.html docs/formatdomain.html.in | 34 ++++++++++++- docs/schemas/domain.rng | 14 +++++ src/conf/domain_conf.c | 49 ++++++++++++++++++- src/conf/domain_conf.h | 11 ++++ src/libvirt_private.syms | 2 + src/qemu/qemu_capabilities.c | 3 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 23 +++++++++ tests/qemuhelptest.c | 3 +- .../qemuxml2argv-disk-asyncio.args | 11 ++++ .../qemuxml2argvdata/qemuxml2argv-disk-asyncio.xml | 51 ++++++++++++++++++++ tests/qemuxml2argvtest.c | 3 + 12 files changed, 201 insertions(+), 4 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-asyncio.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-asyncio.xml diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index 98fb2b4..8d23740 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -767,7 +767,7 @@ </disk> ... <disk type='network'> - <driver name="qemu" type="raw" io="threads"/> + <driver name="qemu" type="raw" io="threads" asyncio="on"/> <source protocol="sheepdog" name="image_name"> <host name="hostname" port="7000"/> </source> @@ -851,6 +851,20 @@ policies on I/O; qemu guests support "threads" and "native". <span class="since">Since 0.8.8</span> </li> + <li> + The optional <code>asyncio</code> attribute allows users to + set <a href='https://patchwork.kernel.org/patch/43390/'> + domain I/O asynchronous handling</a> for disk device. + The default is left to the discretion of the hypervisor. + Accepted values are "on" and "off".

[libvirt] [PATCH] qemu: Translate boot config into bootindex if possible
by Jiri Denemark 15 Jun '11

15 Jun '11

Prefer bootindex=N option for -device over the old way -boot ORDER possibly accompanied with boot=on option for -drive. This gives us full control over which device will actually be used for booting guest OS. Moreover, if qemu doesn't support boot=on, this is the only way to boot of certain disks in some configurations (such as virtio disks when used together IDE disks) without transforming domain XML to use per device boot elements. --- src/qemu/qemu_command.c | 141 +++++++++++++------- src/qemu/qemu_command.h | 4 +- src/qemu/qemu_hotplug.c | 14 +- .../qemuxml2argv-boot-complex-bootindex.args | 30 ++++ .../qemuxml2argv-boot-complex-bootindex.xml | 65 +++++++++ .../qemuxml2argv-boot-complex.args | 30 ++++ .../qemuxml2argvdata/qemuxml2argv-boot-complex.xml | 65 +++++++++ ...xml2argv-boot-menu-disable-drive-bootindex.args | 13 ++ ...uxml2argv-boot-menu-disable-drive-bootindex.xml | 27 ++++ .../qemuxml2argv-boot-menu-disable-drive.args | 14 ++ .../qemuxml2argv-boot-menu-disable-drive.xml | 27 ++++ .../qemuxml2argv-boot-menu-enable.args | 14 ++ .../qemuxml2argv-boot-menu-enable.xml | 27 ++++ .../qemuxml2argv-disk-drive-no-boot.args | 18 +++ .../qemuxml2argv-disk-drive-no-boot.xml | 38 ++++++ tests/qemuxml2argvtest.c | 17 +++ 16 files changed, 489 insertions(+), 55 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-boot-complex-bootindex.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-boot-complex-bootindex.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-boot-complex.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-boot-complex.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-boot-menu-disable-drive-bootindex.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-boot-menu-disable-drive-bootindex.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-boot-menu-disable-drive.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-boot-menu-disable-drive.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-boot-menu-enable.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-boot-menu-enable.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-drive-no-boot.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-drive-no-boot.xml diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index ef2d002..277fa99 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -1189,7 +1189,7 @@ qemuSafeSerialParamValue(const char *value) char * qemuBuildDriveStr(virDomainDiskDefPtr disk, - int bootable, + bool bootable, virBitmapPtr qemuCaps) { virBuffer opt = VIR_BUFFER_INITIALIZER;

[libvirt] [libvirt-php] - zend_mm_heap corrupted
by Henrik Jönsson 15 Jun '11

15 Jun '11

[libvirt-php] Hello! I am using Libvirt-php for a private project, i do however have a problem that seems to occur when i call any function that returns a domain resource. I have gotten 3 different errors so far. First i had a problem with php memory usage going extreme(2gb), then i have had some apache segmentation fault ending up in apache killing the process. I have also had zend_mm_heap corrupted which i think is the most common one. I have tried with Ubuntu 10.04, 10.10 and 11.04 repository versions of Apache. Other than that i am using libvirt version 0.9.1 and libvirt-php version 0.4.1. This is within the contexts of Drupal as i am using the code in a Drupal module. I have checked out the source code for libvirt-php but since i am no C/C++ developer i have a hard time figuring out what the issue might be. Some help would be greatly appreciated. :) Best Regards! /Henrik

[libvirt] RFC (v3): Add virDomainBlockPull API family to libvirt
by Adam Litke 15 Jun '11

15 Jun '11

I didn't receive too many comments on the last round. That probably means everybody has been busy with the 0.9.2 release. I think this is ready to be committed but we can wait until the qemu side has gone up (which should happen any day now). Changes since V2: - Rebased - Ensure error messages are consistent between JSON and Text interfaces - Added additional tests to the sample test bucket Changes since V1: - Rebased to incorporate changes to generator and removal of static driver structure initializers - Other small fixups suggested by Matthias Bolte 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. make check: PASS make syntax-check: PASS make -C tests valgrind: PASS I am testing this API with Python Unittest (see the last patch). [PATCH 1/8] Add new API virDomainBlockPull* to headers [PATCH 2/8] virDomainBlockPull: Implement the main entry points [PATCH 3/8] Add virDomainBlockPull support to the remote driver [PATCH 4/8] Implement virDomainBlockPull for the qemu driver [PATCH 5/8] Enable the virDomainBlockPull API in virsh [PATCH 6/8] Enable virDomainBlockPull in the python API.

[libvirt] [PATCH] spice: add disableCopyPaste property
by Eric Blake 14 Jun '11

[libvirt] [PATCHv7 0/12] Add virNodeGet{CPU,Memory}Stats() API
by Minoru Usui 14 Jun '11

14 Jun '11

Hi, everyone. I re-wrote virNodeGetCPUStats(), virNodeGetMemoryStats(). This time, I merged two APIs to same patch series. Changes v6->v7 - Add cpuNum/cellNum arguments to return specified cpu/cell statistics only. 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 v2] Fix autostart flag when loading running domains
by Michael Chapman 14 Jun '11

14 Jun '11

Drivers load running persistent and transient domain configs before inactive persistent domain configs, however only the latter would set a domain's autostart flag. This mismatch between the loaded and on-disk state could later cause problems with "virsh autostart": # virsh autostart example error: Failed to mark domain example as autostarted error: Failed to create symlink '/etc/libvirt/qemu/autostart/example.xml to '/etc/libvirt/qemu/example.xml': File exists This patch ensures the autostart flag is set correctly even when the domain is already defined.

[libvirt] [PATCH v2] virsh: Increase device-detach intelligence
by Michal Prívozník 14 Jun '11

14 Jun '11

Up to now users have to give a full XML description on input when device-detaching. If they omitted something it lead to unclear error messages (like generated MAC wasn't found, etc.). With this patch users can specify only those information which specify one device sufficiently precise. Remaining information is completed from domain. --- diff to v1: -rebase to current HEAD -add a little bit comments tools/virsh.c | 266 +++++++++++++++++++++++++++++++++++++++++++++++++++++---- 1 files changed, 250 insertions(+), 16 deletions(-) diff --git a/tools/virsh.c b/tools/virsh.c index d98be1c..5c2634c 100644 --- a/tools/virsh.c +++ b/tools/virsh.c @@ -9302,6 +9302,226 @@ cmdAttachDevice(vshControl *ctl, const vshCmd *cmd) return true; } +/** + * Check if n1 is superset of n2, meaning n1 contains all elements and + * attributes as n2 at lest.
