[libvirt PATCH v2 0/5] Add support for vDPA block devices
by Jonathon Jongsma 13 Sep '23

13 Sep '23

see https://bugzilla.redhat.com/show_bug.cgi?id=1900770. Changes in v2: - Don't use virStorageSource->path for vdpa device path to avoid clashing with existing path functionality - Move vdpa device opening to the qemuProcessPrepareHostStorageSource() function rather than the qemuDomainPrepareStorageSource() function. This also required some additional support in the tests for setting up the objects properly for testing. - rebased to latest master branch Jonathon Jongsma (5): conf: add ability to configure a vdpa block disk device qemu: add virtio-blk-vhost-vdpa capability qemu: make vdpa connect function more generic qemu: consider vdpa block devices for memlock limits qemu: Implement support for vDPA block devices docs/formatdomain.rst | 19 +++++++++- src/ch/ch_monitor.c | 1 + src/conf/domain_conf.c | 8 ++++ src/conf/schemas/domaincommon.rng | 13 +++++++ src/conf/storage_source_conf.c | 7 +++- src/conf/storage_source_conf.h | 2 + src/libxl/xen_xl.c | 1 + src/qemu/qemu_block.c | 20 ++++++++++ src/qemu/qemu_capabilities.c | 2 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 24 +++++++++++- src/qemu/qemu_command.h | 1 + src/qemu/qemu_domain.c | 12 +++++- src/qemu/qemu_interface.c | 23 ------------ src/qemu/qemu_interface.h | 2 - src/qemu/qemu_migration.c | 2 + src/qemu/qemu_process.c | 34 +++++++++++++++++ src/qemu/qemu_snapshot.c | 4 ++ src/qemu/qemu_validate.c | 33 +++++++++++++++-- src/storage_file/storage_source.c | 1 + .../caps_8.1.0_x86_64.xml | 1 + tests/qemuhotplugmock.c | 4 +- .../disk-vhostvdpa.x86_64-latest.args | 37 +++++++++++++++++++ tests/qemuxml2argvdata/disk-vhostvdpa.xml | 21 +++++++++++ tests/qemuxml2argvmock.c | 2 +- tests/qemuxml2argvtest.c | 34 +++++++++++++++++ tests/testutilsqemu.c | 11 ++++++ tests/testutilsqemu.h | 2 + 28 files changed, 285 insertions(+), 37 deletions(-) create mode 100644 tests/qemuxml2argvdata/disk-vhostvdpa.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/disk-vhostvdpa.xml -- 2.41.0

[PATCH] virnetdevopenvswitch: Propagate OVS error messages
by Michal Privoznik 08 Sep '23

08 Sep '23

When configuring OVS interfaces/bridges we spawn 'ovs-vsctl' with appropriate arguments and if it exited with a non-zero status we report a generic error message, like "Unable to add port vnet0 to OVS bridge ovsbr0". This is all cool, but the real reason why operation failed is hidden in (debug) logs because that's where virCommandRun() reports it unless caller requested otherwise. This is a bit clumsy because then we have to ask users to turn on debug logs and reproduce the problem again, e.g. [1]. Therefore, in cases where an error is reported to the user - just read ovs-vsctl's stderr and include it in the error message. For other cases (like VIR_DEBUG/VIR_WARN) - well they are meant to end up in (debug) logs anyway. 1: https://mail.openvswitch.org/pipermail/ovs-discuss/2023-September/052640.ht… Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- src/util/virnetdevopenvswitch.c | 93 ++++++++++++++++++++------------- 1 file changed, 58 insertions(+), 35 deletions(-) diff --git a/src/util/virnetdevopenvswitch.c b/src/util/virnetdevopenvswitch.c index 8dad6ed2bd..d836d05845 100644 --- a/src/util/virnetdevopenvswitch.c +++ b/src/util/virnetdevopenvswitch.c @@ -54,10 +54,14 @@ virNetDevOpenvswitchSetTimeout(unsigned int timeout) } static virCommand * -virNetDevOpenvswitchCreateCmd(void) +virNetDevOpenvswitchCreateCmd(char **errbuf) { virCommand *cmd = virCommandNew(OVS_VSCTL);

[PATCH] manpage: virsh: Note that 'virsh undefine --remove-all-storage' doesn't remove backing images
by Peter Krempa 07 Sep '23

Removing a backing image could break other image chains as it's theoretically possible to share backing chains. As --storage/--remove-all-storage is fully implemented in virsh as a helper option, which enumerates and deletes VM's volumes. We do not plan to make it any more complicated.

[PATCH Libvirt v3 00/10] Support dirty page rate upper limit
by ~hyman 07 Sep '23

07 Sep '23

Hi, This is the latest version for the series, please review. Thanks, Yong v3: - rebase on master and fix conflicts - refactor the comments and update the version tag v2: The patch set introduce a new API virDomainSetVcpuDirtyLimit to allow upper Apps to set upper limits of dirty page rate for virtual CPUs, the corresponding virsh API as follows: limit-dirty-page-rate <domain> <rate> [--vcpu <number>] \ [--config] [--live] [--current] We put the dirty limit persistent info with the "vcpus" element in domain XML and extend dirtylimit statistics for domGetStats: <domain> ... <vcpu current='2'>3</vcpu> <vcpus> <vcpu id='0' hotpluggable='no' dirty_limit='10' order='1'.../> <vcpu id='1' hotpluggable='yes' dirty_limit='10' order='2'.../> </vcpus> ... </domain> If --vcpu option is not passed in the virsh command, set all virtual CPUs; if rate is set to zero, cancel the upper limit. Examples: To set the dirty page rate upper limit 10 MB/s for all virtual CPUs in c81_node1, use: # virsh limit-dirty-page-rate c81_node1 --rate 10 --live Set dirty page rate limit 10(MB/s) for all virtual CPUs successfully # virsh dumpxml c81_node1 | grep dirty_limit <vcpu id='0' enabled='yes' hotpluggable='no' order='1' dirty_limit='10'/> <vcpu id='1' enabled='yes' hotpluggable='no' order='2' dirty_limit='10'/> <vcpu id='2' enabled='yes' hotpluggable='no' order='3' dirty_limit='10'/> <vcpu id='3' enabled='no' hotpluggable='yes' dirty_limit='10'/> <vcpu id='4' enabled='no' hotpluggable='yes' dirty_limit='10'/> ...... Query the dirty limit info dynamically: # virsh domstats c81_node1 --dirtylimit Domain: 'c81_node1' dirtylimit.vcpu.0.limit=10 dirtylimit.vcpu.0.current=0 dirtylimit.vcpu.1.limit=10 dirtylimit.vcpu.1.current=0 dirtylimit.vcpu.2.limit=10 dirtylimit.vcpu.2.current=0 dirtylimit.vcpu.3.limit=10 dirtylimit.vcpu.3.current=0 dirtylimit.vcpu.4.limit=10 dirtylimit.vcpu.4.current=0 ...... To cancel the upper limit, use: # virsh limit-dirty-page-rate c81_node1 --rate 0 --live Cancel dirty page rate limit for all virtual CPUs successfully # virsh dumpxml c81_node1 | grep dirty_limit # virsh domstats c81_node1 --dirtylimit Domain: 'c81_node1' The dirty limit uses the QEMU dirty-limit feature introduced since 7.1.0, this feature allows CPU to be throttled as needed to keep their dirty page rate within the limit. It could, in some scenes, be used to provide quality-of-service in the aspect of the memory workload for virtual CPUs and QEMU itself use the feature to implement the dirty-limit throttle algorithm and apply it on the live migration, which improve responsiveness of large guests during live migration and can result in more stable read performance. The other application scenarios remain unexplored, before that, Libvirt could provide the basic API.

virDomainGetJobStats not populating VIR_DOMAIN_JOB_DISK_BPS
by João Vilaça 06 Sep '23

06 Sep '23

Hello, I'm using https://gitlab.com/libvirt/libvirt-go-module and executing 'GetJobStats' to get information about the progress of a VM with a disk migration in KubeVirt. Everything works correctly and the migration is successful, with the disk correctly copied. Across multiple executions of 'GetJobStats' while copying the disk, I get the information about data: *DataTotal:151592960 DataProcessedSet:true DataProcessed:163080901 DataRemainingSet:true DataRemaining:266240* about disk total values: *DiskTotal:21037056 DiskProcessedSet:true DiskProcessed:13631488 DiskRemainingSet:true DiskRemaining:7405568* but '*DiskBpsSet:false *' and '*DiskBps:0 *' are always false and 0. Even when I run 'virsh domjobinfo', I get Data and File absolute values, but not the throughput. Is QEMU not reporting this data? Can this be a bug? -- kind regards, João Vilaça

[PATCH 00/51] Finish conversion of all test cases in qemuxml2argvtest to real capabilities
by Peter Krempa 06 Sep '23

06 Sep '23

This series converts all outstanding test cases to use real capabilities. In the process few cases of pointless tests or features which are supported by every version of qemu were identified and addressed. To simplify the bulk of the conversion I've opted to simply set the most common capabilities in DO_TEST and DO_TEST_NOCAPS in addition to what the test asked for. This is done in a handful of patches and allows then a bulk conversion of many tests with no changes in the output files. I've payed special attention to CPU tests were I've ensured that they are semantically testing what they were before. Peter Krempa (51): qemu: Always assume support for QEMU_CAPS_PIIX_DISABLE_S* and QEMU_CAPS_ICH9_DISABLE_S* qemu: capabilities: Retire QEMU_CAPS_ICH9_DISABLE_S* and QEMU_CAPS_ICH9_DISABLE_S*

[PATCH Libvirt v2 00/10] Support dirty page rate upper limit
by ~hyman 05 Sep '23

05 Sep '23

Hi, This is the latest version for the series, comparing with version 1, there are some key modifications has made inspired and suggested by Peter, see as follows: 1. Introduce XML for dirty limit persistent configuration 2. Merge the cancel API into the set API 3. Extend the domstats/virDomainListGetStats API for dirty limit information query 4. Introduce the virDomainModificationImpact flags to control the behavior of the API 5. Enrich the comments and docs about the feature and API The patch set introduce the new API virDomainSetVcpuDirtyLimit to allow upper Apps to set upper limits of dirty page rate for virtual CPUs, the corresponding virsh API as follows: # limit-dirty-page-rate <domain> <rate> [--vcpu <number>] \ [--config] [--live] [--current] We put the dirty limit persistent info with the "vcpus" element in domain XML and extend dirtylimit statistics for domGetStats: <domain> ... <vcpu current='2'>3</vcpu> <vcpus> <vcpu id='0' hotpluggable='no' dirty_limit='10' order='1'.../> <vcpu id='1' hotpluggable='yes' dirty_limit='10' order='2'.../> </vcpus> ... If --vcpu option is not passed in the virsh command, set all virtual CPUs; if rate is set to zero, cancel the upper limit. Examples: To set the dirty page rate upper limit 10 MB/s for all virtual CPUs in c81_node1, use: [root@srv2 my_libvirt]# virsh limit-dirty-page-rate c81_node1 --rate 10 --live Set dirty page rate limit 10(MB/s) for all virtual CPUs successfully [root@srv2 my_libvirt]# virsh dumpxml c81_node1 | grep dirty_limit <vcpu id='0' enabled='yes' hotpluggable='no' order='1' dirty_limit='10'/> <vcpu id='1' enabled='yes' hotpluggable='no' order='2' dirty_limit='10'/> <vcpu id='2' enabled='yes' hotpluggable='no' order='3' dirty_limit='10'/> <vcpu id='3' enabled='no' hotpluggable='yes' dirty_limit='10'/> <vcpu id='4' enabled='no' hotpluggable='yes' dirty_limit='10'/> ...... Query the dirty limit info dynamically: [root@srv2 my_libvirt]# virsh domstats c81_node1 --dirtylimit Domain: 'c81_node1' dirtylimit.vcpu.0.limit=10 dirtylimit.vcpu.0.current=0 dirtylimit.vcpu.1.limit=10 dirtylimit.vcpu.1.current=0 dirtylimit.vcpu.2.limit=10 dirtylimit.vcpu.2.current=0 dirtylimit.vcpu.3.limit=10 dirtylimit.vcpu.3.current=0 dirtylimit.vcpu.4.limit=10 dirtylimit.vcpu.4.current=0 ...... To cancel the upper limit, use: [root@srv2 my_libvirt]# virsh limit-dirty-page-rate c81_node1 \ --rate 0 --live Cancel dirty page rate limit for all virtual CPUs successfully [root@srv2 my_libvirt]# virsh dumpxml c81_node1 | grep dirty_limit [root@srv2 my_libvirt]# virsh domstats c81_node1 --dirtylimit Domain: 'c81_node1' The dirty limit uses the QEMU dirty-limit feature introduced since 7.1.0, this feature allows CPU to be throttled as needed to keep their dirty page rate within the limit. It could, in some scenes, be used to provide quality-of-service in the aspect of the memory workload for virtual CPUs and QEMU itself use the feature to implement the dirty-limit throttle algorithm and apply it on the live migration, which improve responsiveness of large guests during live migration and can result in more stable read performance. The other application scenarios remain unexplored, before that, Libvirt could provide the basic API.

by Philipp Hahn 05 Sep '23

05 Sep '23

Hello, "pip install libvirt-python" does not work in several cases as that requires the low-level C library, compilers, tools, and Python header files to be installed. This prevents the use of "libvirt" in scenarios, where "root" privileges are not available to install these dependencies, e.g. running "libvirt" inside a JupyterHub notebook for gathering statistics. This also breaks the adoption on Windows, see <https://gitlab.com/libvirt/libvirt-python/-/issues/7> and <https://gitlab.com/libvirt/libvirt-python/-/issues/6> Looking at <https://libvirt.org/bindings.html> and <https://gitlab.com/libvirt> I only see "bindings" for the low-level C library. Does someone know of a "pure Python binding" for talking to a remote "libvirtd", either via "+ssh" or "+tls"? Or is there another "trick" to talk to libvirtd? And no, parsing the output of subprocess.run("ssh ... virsh ...") is not an option ;-) Philipp -- Philipp Hahn Open Source Software Engineer Univention GmbH Mary-Somerville-Str. 1 28359 Bremen Germany | Deutschland Phone: +49 (0)421 22232-0 | E-Mail: info(a)univention.de https://www.univention.de | https://www.univention.com Managing Directors: Peter H.

[PATCH] conf: Generate MAC address instead of keeping all zeroes
by Martin Kletzander 04 Sep '23

04 Sep '23

When we parse <mac address="00:00:00:00:00:00"/> we keep that in memory and pass it down to the hypervisor. However, that MAC address is not strictly valid as it is not marked as locally administered (bit 0x02) but it is not even globally unique. It is also used for loopback device on Linux, for example. And QEMU sees such MAC address just as "not specified" and generates a new one that libvirt does not even know about. So to make the overall experience better we now generate it if the supplied one is all clear.

[libvirt PATCH 00/33] ci: Unify the GitLab CI jobs with local executions && adopt lcitool container executions
by Erik Skultety 01 Sep '23

01 Sep '23

Technically a v2 of: https://listman.redhat.com/archives/libvir-list/2023-February/237552.html However, the approach here is slightly different and what that series said about migration to lcitool container executions as a replacement for ci/Makefile is actually done here. One of the core problems of the above pointed out in review was that more Shell logic was introduced including CLI parsing, conditional executions, etc. which we fought hard to get rid of in the past. I reworked the Shell functions quite a bit and dropped whatever extra Shell logic the original series added. Obviously we can't get rid of Shell completely because of .gitlab-ci.yml and so I merely extracted the recipes into functions which are then sourced as ci/build.sh and executed. Now, that on its own would hide the actual commands being run in the GitLab job log, so before any command is actually executed, it is formatted with a color sequence so we don't miss that information as that would be a regression to the status quo. Lastly, this series then takes the effort inside the ci/build.sh script and basically mirrors whatever GitLab would do to run a job inside a local container which is executed by lcitool (yes, we already have that capability). Please give this a try and I'm already looking forward to comments as I'd like to expand this effort to local VM executions running the TCK integration tests, so this series is quite important in that regard.

Release of libvirt-9.7.0
by Jiri Denemark 01 Sep '23

01 Sep '23

The 9.7.0 release of both libvirt and libvirt-python is tagged and signed tarballs and source RPMs are available at https://download.libvirt.org/ https://download.libvirt.org/python/ Thanks everybody who helped with this release by sending patches, reviewing, testing, or providing feedback. Your work is greatly appreciated. * New features * qemu: basic support for use of "VFIO variant" drivers A VFIO variant driver is a device-specific driver that can be used in place of the generic vfio-pci driver, and provides extra functionality to support things like live migration of guests with vfio-assigned devices. It can currently be used by: 1) setting ``managed='no'`` in the XML configuration for the device 2) pre-binding the variant driver using the ``--driver`` option of ``virsh nodedev-detach``. * Bug fixes * qemu: Various fixes to firmware selection The changes made to firmware selection in libvirt 9.2.0 have unfortunately introduced a number of regressions. All known issues in this area have now been resolved. Enjoy. Jirka

[libvirt PATCH v2 0/6] external snapshot revert fixes
by Pavel Hrdina 01 Sep '23

01 Sep '23

This fixes reverting external snapshots to not error out in cases where it should work and makes it correctly load the memory state when reverting to snapshot of running VM.

Sunset libvirt-snmp?
by Michal Prívozník 01 Sep '23

01 Sep '23

It's been a while since libvirt-snmp was actively developed. Now it receives only libvirt-ci related commits. The code compiles with net-snmp-5.9.3 but the freshly released net-snmp-5.9.4 [1] breaks compilation [2]. Now, libvirt-snmp has this crazy architecture, where some sources are manually generated from src/LIBVIRT-MIB.txt, then edited (added code to talk to libvirt) and then added to git. This is labor extensive and since I don't think libvirt-snmp is actually used I'd like to sunset it. According to repology [3] only Gentoo (and its clones) has the latest version (released ~5 years ago). And I doubt it has any real users there. Thoughts? 1: https://sourceforge.net/projects/net-snmp/files/net-snmp/5.9.4/ 2: https://bugs.gentoo.org/show_bug.cgi?id=912582 2: https://repology.org/project/libvirt-snmp/versions Michal

[PATCH] virsh: Fix net-desc --config output
by K Shiva Kiran 01 Sep '23

01 Sep '23

Fixes the following bug: Command: `net-desc --config [--title] my_network` Expected Output: Title/Description of persistent config Output: Title/Description of live config This was caused due to the usage of a single `flags` variable in `virshGetNetworkDescription()` which ended up in a wrong enum being passed to `virNetworkGetMetadata()` (enum being that of LIVE instead of CONFIG). Although the domain object has the same code, this didn't cause a problem there because the enum values of `VIR_DOMAIN_INACTIVE_XML` and `VIR_DOMAIN_METADATA_CONFIG` turn out to be the same (1 << 1), whereas they are not for network equivalent ones (1 << 0, 1 << 1).

[PATCH v2] accel: Remove HAX accelerator
by Philippe Mathieu-Daudé 31 Aug '23

31 Aug '23

HAX is deprecated since commits 73741fda6c ("MAINTAINERS: Abort HAXM maintenance") and 90c167a1da ("docs/about/deprecated: Mark HAXM in QEMU as deprecated"), released in v8.0.0. Per the latest HAXM release (v7.8 [*]), the latest QEMU supported is v7.2: Note: Up to this release, HAXM supports QEMU from 2.9.0 to 7.2.0. The next commit (https://github.com/intel/haxm/commit/da1b8ec072) added: HAXM v7.8.0 is our last release and we will not accept pull requests or respond to issues after this. It became very hard to build and test HAXM. Its previous maintainers made it clear they won't help. It doesn't seem to be a very good use of QEMU maintainers to spend their time in a dead project. Save our time by removing this orphan zombie code.

[PULL 01/41] accel: Remove HAX accelerator
by Philippe Mathieu-Daudé 31 Aug '23

31 Aug '23

HAX is deprecated since commits 73741fda6c ("MAINTAINERS: Abort HAXM maintenance") and 90c167a1da ("docs/about/deprecated: Mark HAXM in QEMU as deprecated"), released in v8.0.0. Per the latest HAXM release (v7.8 [*]), the latest QEMU supported is v7.2: Note: Up to this release, HAXM supports QEMU from 2.9.0 to 7.2.0. The next commit (https://github.com/intel/haxm/commit/da1b8ec072) added: HAXM v7.8.0 is our last release and we will not accept pull requests or respond to issues after this. It became very hard to build and test HAXM. Its previous maintainers made it clear they won't help. It doesn't seem to be a very good use of QEMU maintainers to spend their time in a dead project. Save our time by removing this orphan zombie code.

[libvirt PATCH] rpm: Recommend libvirt-daemon for with_modular_daemons distros
by Andrea Bolognani 31 Aug '23

31 Aug '23

A default deployment on modern distros uses modular daemons but switching back to the monolithic daemon, while not recommended, is still considered a perfectly valid option. For a monolithic daemon deployment, the upgrade to libvirt 9.2.0 or newer works as expected; a subsequent call to dnf autoremove, however, results in the libvirt-daemon package being removed and the deployment no longer working. In order to avoid that situation, mark the libvirt-daemon as recommended. This will unfortunately result in it being included in most installations despite not being necessary, but considering that the alternative is breaking existing setups on upgrade it feels like a reasonable tradeoff. Moreover, since the dependency on libvirt-daemon is just a weak one, it's still possible for people looking to minimize the footprint of their installation to manually remove the package after installation, mitigating the drawbacks of this approach. https://bugzilla.redhat.com/show_bug.cgi?id=2232805 Signed-off-by: Andrea Bolognani <abologna(a)redhat.com> --- libvirt.spec.in | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/libvirt.spec.in b/libvirt.spec.in index 6bbc7a0e9a..b471afebb1 100644 --- a/libvirt.spec.in +++ b/libvirt.spec.in @@ -830,6 +830,7 @@ Requires: libvirt-daemon-log = %{version}-%{release} Requires: libvirt-daemon-lock = %{version}-%{release} Requires: libvirt-daemon-plugin-lockd = %{version}-%{release} Requires: libvirt-daemon-proxy = %{version}-%{release} +Recommends: libvirt-daemon = %{version}-%{release} %else Requires: libvirt-daemon = %{version}-%{release} %endif @@ -857,6 +858,7 @@ Requires: libvirt-daemon-log = %{version}-%{release} Requires: libvirt-daemon-lock = %{version}-%{release} Requires: libvirt-daemon-plugin-lockd = %{version}-%{release} Requires: libvirt-daemon-proxy = %{version}-%{release} +Recommends: libvirt-daemon = %{version}-%{release} %else Requires: libvirt-daemon = %{version}-%{release} %endif @@ -881,6 +883,7 @@ Summary: Server side daemon & driver required to run LXC guests %if %{with_modular_daemons} Requires: libvirt-daemon-common = %{version}-%{release} Requires: libvirt-daemon-proxy = %{version}-%{release} +Recommends: libvirt-daemon = %{version}-%{release} %else Requires: libvirt-daemon = %{version}-%{release} %endif @@ -906,6 +909,7 @@ Requires: libvirt-daemon-common = %{version}-%{release} Requires: libvirt-daemon-lock = %{version}-%{release} Requires: libvirt-daemon-plugin-lockd = %{version}-%{release} Requires: libvirt-daemon-proxy = %{version}-%{release} +Recommends: libvirt-daemon = %{version}-%{release} %else Requires: libvirt-daemon = %{version}-%{release} %endif @@ -930,6 +934,7 @@ Summary: Server side daemon & driver required to run VirtualBox guests %if %{with_modular_daemons} Requires: libvirt-daemon-common = %{version}-%{release} Requires: libvirt-daemon-proxy = %{version}-%{release} +Recommends: libvirt-daemon = %{version}-%{release} %else Requires: libvirt-daemon = %{version}-%{release} %endif -- 2.41.0
