[libvirt] [PATCH RESEND v2 0/4] re-introduce <acpi-hotplug-bridge>

by Ani Sinha

Change log: v2: rebased the patchset. Laine's response is appended at the end. I am re-introducing the patchset for <acpi-hotplug-bridge> which got reverted here few months back: https://www.spinics.net/linux/fedora/libvir/msg224089.html The reason for the reversal was that there seemed to be some instability/issues around the use of the qemu commandline which this patchset tries to support. In particular, some guest operating systems did not like the way QEMU was trying to disable native hotplug on pcie root ports. Subsequently, in QEMU 6.2, we have changed our mechanism using which we disable native hotplug. As I understand, we do not have any reported issues so far in 6.2 around this area. QEMU will enter a soft feature freeze in the first week of march in prep for 7.0 release. Libvirt is also entering a new release cycle phaze. Hence, I am introducing this patchset early enough in the release cycles so that if we do see any issues on the qemu side during the rc0, rc1 cycles and if reversal of this patchset is again required, it can be done in time before the next libvirt release end of March. All the patches in this series had been previously reviewed. Some subsequent fixes were made after my initial patches were pushed. I have squashed all those fixes and consolidated them into four patches. I have also updated the documentation to reflect the new changes from the QEMU side and rebased my changes fixing the tests in the process. What changed in QEMU post version 6.1 ? ========================================= We have made basically two major changes in QEMU. First is this change: (1) commit 211afe5c69b597acf85fdd577eb497f5be1ffbd8 Author: Julia Suvorova <jusual(a)redhat.com> Date: Fri Nov 12 06:08:56 2021 -0500 hw/i386/acpi-build: Deny control on PCIe Native Hot-plug in _OSC There are two ways to enable ACPI PCI Hot-plug: * Disable the Hot-plug Capable bit on PCIe slots. This was the first approach which led to regression [1-2], as I/O space for a port is allocated only when it is hot-pluggable, which is determined by HPC bit. * Leave the HPC bit on and disable PCIe Native Hot-plug in _OSC method. This removes the (future) ability of hot-plugging switches with PCIe Native hotplug since ACPI PCI Hot-plug only works with cold-plugged bridges. If the user wants to explicitely use this feature, they can disable ACPI PCI Hot-plug with: --global ICH9-LPC.acpi-pci-hotplug-with-bridge-support=off Change the bit in _OSC method so that the OS selects ACPI PCI Hot-plug instead of PCIe Native.

Tsirkin <mst(a)redhat.com> Signed-off-by: Michael S. Tsirkin <mst(a)redhat.com> The patch description says it all. Instead of masking out the HPC bit in pcie slots, we keep them turned on. Instead, we do not advertize native hotplug capability for PCIE using _OSC control method. See section 6.2.11 in ACPI spec 6.2. At the same time, we turn on ACPI hotplug for these slots so now the guest OS can select ACPI hotplug instead. The second change is introduction of a property with which we keep the existing behavior for pc-q35-6.1 machines. This means HPC bit is masked and ACPI hotplug is enabled by default for pcie root ports. The QEMU commit is: (2) commit c318bef76206c2ecb6016e8e68c4ac6ff9a4c8cb Author: Julia Suvorova <jusual(a)redhat.com> Date: Fri Nov 12 06:08:54 2021 -0500 hw/acpi/ich9: Add compat prop to keep HPC bit set for 6.1 machine type To solve issues [1-2] the Hot Plug Capable bit in PCIe Slots will be turned on, while the switch to ACPI Hot-plug will be done in the DSDT table. Introducing 'x-keep-native-hpc' property disables the HPC bit only in 6.1 and as a result keeps the forced 'reserve-io' on pcie-root-ports in 6.1 too.

Tsirkin <mst(a)redhat.com> Signed-off-by: Michael S. Tsirkin <mst(a)redhat.com> Lastly, as a related side note, because from QEMU 6.2 onwards, we do not mask out HPC bit in PCIE, the work done by this patch is no longer needed: (3) commit e2a6290aab578b2170c1f5909fa556385dc0d820 Author: Marcel Apfelbaum <marcel.apfelbaum(a)gmail.com> Date: Mon Aug 2 12:00:57 2021 +0300 hw/pcie-root-port: Fix hotplug for PCI devices requiring IO Q35 has now ACPI hotplug enabled by default for PCI(e) devices. As opposed to native PCIe hotplug, guests like Fedora 34 will not assign IO range to pcie-root-ports not supporting native hotplug, resulting into a regression. Reproduce by: qemu-bin -M q35 -device pcie-root-port,id=p1 -monitor stdio device_add e1000,bus=p1 In the Guest OS the respective pcie-root-port will have the IO range disabled. Fix it by setting the "reserve-io" hint capability of the pcie-root-ports so the firmware will allocate the IO range instead.

Tsirkin <mst(a)redhat.com> Signed-off-by: Michael S. Tsirkin <mst(a)redhat.com> This is what commit (2) alludes to. In pc-q35-6.1 machines we do need patch (3) since we mask out HPC bit from pcie ports. I know this is convoluted mess. In fairness I am trying all I can in my spare time to help from the QEMU side. I am determined to see this patchset through into libvirt. Thanks Laine's comments ... My memory isn't completely clear, but I think there was also the issue that the option claims to enable ACPI hotplug when set to on, but instead what it actually does (in the Q35 case at least) is to enable native PCI hotplug when set to off (without actually disabling ACPI hotplug) and disable native PCI hotplug when set to on, or something like that. This ends up leaving it up to the guest OS to decide which type of hotplug to use, meaning its decision could override what's in the libvirt config, thus confusing everyone. Again, I probably have the details mixed up, but it was something like this. I asked mst about this this morning, and he suggested something that you've already done - Cc'ing the series to qemu-devel and the relevant maintainers so we can have a discussion with all involved parties about their opinions on whether we really should expose this existing option in libvirt, or if we should instead have two new options that are more orthogonal about enabling/disabling the two types of hotplug, so that libvirt config can more accurately represent what is being presented to the guest rather than a "best guess" of what we think the guest is going to do with what is presented. (Michael did also say that, with the current flurry of bug reports for the QEMU rc's, this discusion may not happen until closer to release when the bug reports die down. I know this doesn't mesh with your desire to "push now to allow for testing" (which in general would be a good thing if we were certain that we wanted the option like this and were just expecting some minor bugs that could be fixed), but my opinion is that 1) it's possible for anyone interested to test the functionality using <qemu:commandline>, and 2) we should avoid turning libvirt git into a revolving door of experiments. The only practical difference between using <qemu:commandline> and having a dedicated option is that the use of <qemu:commandline> causes the domain to be tainted, and the XML is a bit more complicated. But since the people we're talking about here will already have built their own libvirt binaries, the tainted status of any guests is irrelevant and the extra complexity of using <qemu:commandline> is probably trivial to them :-).

[libvirt PATCH v2] iohelper: some refactoring

by Claudio Fontana

while doing research with alternative implementations of runIO, it seemed necessary to do some refactoring, in order to separate parameter setting from the actual copy, so that alternative copy methods can be researched and hopefully eventually implemented. No functional changes are expected.

[RFC PATCH v1 0/5] Add virDomainGetSevAttestationReport API

by Tyler Fanelli

This an RFC discussing a new API, virDomainGetSevAttestationReport (along with a virsh command "domgetsevreport"), with initial QEMU support via the "query-sev-attestation-report" QAPI mechanism. "query-sev-attestation-report" is supplied a base64-encoded 16 byte "mnonce" string as input, with a purpose of being embedded into the attestation report to provide protection. My main point of concern is the design/communication of the virTypedParameterPtr exchanged between the client and libvirtd and how they interact together, as I have seen no other API follow the method I used. Namely, the same virTypedParameterPtr is used for both input _AND_ output. The same virTypedParameterPtr containing the original mnonce string inputted to the API is also used to contain the attestation report upon being returned from the API. This contrasts with much of the APIs I've noticed, which use a virTypedParameterPtr for either input or output, but not both. This patch is not final, as I still would like some human-readable outputting and storage of the attestation report. Looking for thoughts on the design of this API, as well as suggested improvements.

[libvirt PATCH 00/10] Cleanup and test more firmware handling scenarios

by Daniel P. Berrangé

There are a mind bending number of possible ways to configure the firmware with/without NVRAM. Only a small portion are tested and many error scenarios are silently ignored. This series attempts to get coverage of every possible XML config scenario and report explicit errors in all invalid configs. There is an open question on patch 4. Essentially the use of NVRAM combined with writable executable feels like an accidental feature in libvirt that hasn't really been thought through. I'd like to better define expectations here but there are several possible strategies and I'm undecided which is best. Daniel P.

[libvirt RFC] virFile: new VIR_FILE_WRAPPER_BIG_PIPE to improve performance

by Claudio Fontana

the first user is the qemu driver, virsh save/resume would slow to a crawl with a default pipe size (64k). This improves the situation by 400%. Going through io_helper still seems to incur in some penalty (~15%-ish) compared with direct qemu migration to a nc socket to a file.

[PATCH for 8.3.0 00/17] qemu: Stop supporting Ubuntu 1804-ancient qemus

by Peter Krempa

As of April 23 2022, Ubuntu 20.04 will be out for two years, which per our platform support policy means we no longer have to support Ubuntu 18.04. The supported platforms thus will have the following qemu versions: Debian 10/Stable: 3.1 OpenSUSE Leap 15.3: 5.2 Ubuntu 20.04: 4.2 RHEL/Centos 8.4: 4.2 This patchset is targetted to be pushed after the release beginning of April is out so that it's part of the may release. Changes to the RFC version I've posted earlier: - cleanup patches were pushed - added commit removing Ubuntu 1804 from the CI - added removal of QEMU_CAPS_STORAGE_WERROR/QEMU_CAPS_USB_STORAGE_WERROR (noticed while dealing with capability update). - removed commit message bit mentioning Debian backports - removed patch dropping monitor waiting code (Michal's patches may change the expectations. I'll re-visit that commit after this is pushed). Note that the patches posted to the list are heavily trimmed, fetch the full version at: git fetch https://gitlab.com/pipo.sk/libvirt.git qemu-deprecation Peter Krempa (17): ci: Drop Ubuntu 1804

[libvirt PATCH] drivers: Group global feature together

by Andrea Bolognani

All these features are supposed to be handled by the call to virDriverFeatureIsGlobal() placed right above the switch statement, so group them together and add a comment. If any of these features is actually encountered as part of the switch statements, that means there's a bug in the driver and we should error out.

[PATCH v2 0/4] VirtioNet RSS support.

by Andrew Melnychenko

This series of patches add RSS property support for virtio-net-pci. Virtio RSS effectively works with TAP devices, it requires additional vectors for VirtioNet, queues for TAP device, and vCPU cores. Example of device configuration: ``` <interface type="network"> <mac address="52:54:00:c4:90:25"/> <source network="default"/> <model type="virtio"/> <driver name="qemu" queues="9" rss="on" rss_hash_report="off"/> <address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x0"/> </interface> ``` Capability "rss" enables RSS, "rss_hash_report" - enables hashes in vheader. For now, "rss" property will trigger "in-qemu" RSS in most cases. Current Qemu(6.2) supports eBPF RSS that may require additional capabilities. In future, the helper will be provided. And this code is the base for VirtIO RSS. Changes since v1: * refactored patches * changed docs and tests Changes since RFC: * rebased and refactored * added tests * postponed the helper Andrew Melnychenko (4): domain_conf: Added configs for RSS and Hash report. qemu_capabilities: Added capabilites for qemu's "rss" and "hash". qemu_command: Added "rss" and "hash" properties. test: Added xml2argv and xml2xml tests. docs/formatdomain.rst | 18 ++++++++ docs/schemas/domaincommon.rng | 10 +++++ src/conf/domain_conf.c | 31 ++++++++++++- src/conf/domain_conf.h | 2 + src/qemu/qemu_capabilities.c | 2 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 2 + src/qemu/qemu_validate.c | 14 ++++++ .../caps_5.1.0.x86_64.xml | 1 + .../caps_5.2.0.aarch64.xml | 1 + .../qemucapabilitiesdata/caps_5.2.0.ppc64.xml | 1 + .../caps_5.2.0.riscv64.xml | 1 + .../qemucapabilitiesdata/caps_5.2.0.s390x.xml | 1 + .../caps_5.2.0.x86_64.xml | 1 + .../caps_6.0.0.aarch64.xml | 1 + .../qemucapabilitiesdata/caps_6.0.0.s390x.xml | 1 + .../caps_6.0.0.x86_64.xml | 1 + .../caps_6.1.0.x86_64.xml | 1 + .../caps_6.2.0.aarch64.xml | 1 + .../qemucapabilitiesdata/caps_6.2.0.ppc64.xml | 1 + .../caps_6.2.0.x86_64.xml | 1 + .../net-virtio-rss.x86_64-latest.args | 43 +++++++++++++++++++ tests/qemuxml2argvdata/net-virtio-rss.xml | 39 +++++++++++++++++ .../virtio-options.x86_64-latest.args | 2 +- tests/qemuxml2argvdata/virtio-options.xml | 2 +- tests/qemuxml2argvtest.c | 2 + 26 files changed, 178 insertions(+), 3 deletions(-) create mode 100644 tests/qemuxml2argvdata/net-virtio-rss.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/net-virtio-rss.xml -- 2.34.1

libvirt: introduce VIR_DOMAIN_DESTROY_REMOVE_LOGS flag

by Nikolay Shirokovskiy

The patch series based on discussion in RFC [1]. I wonder if we'd better add some property like "transient logs" instead of adding a flag to destoy API. Yes libguestfs uses virDomainDestroyFlags to terminate a VM and it is intended client of this new flag but it or other clients may want to use shutdown API or use autodestroy domains with same log behaviour. Then for the current task we only need to support this property in domain xml I guess.

[PATCH 0/9] Fixes and improvements around virXMLPropTristate*()

by Andrea Bolognani

I have manually audited all commits that have converted existing code to use the new helpers (full list below) and have convinced myself that allowReboot is indeed the only one that requires special handling. Changes from [RFC]: * introduce a separate helper for the one scenario where we need to accept 'default' as input instead of going for an approach that would require updating most callers; * throw in a bunch of extra fixes and improvements. [RFC] https://listman.redhat.com/archives/libvir-list/2022-March/229506.html Commits that performed the conversion in a way that accurately preserved the existing behavior: 14c803cb8276c564d242d4aec8f7d1f64da30321 deac783c86009e0e828746c8c49de70f656aeb85 e1e2e7ec46191a83eadf32be8a87901b01488a6d cea39e95291517ff2a8ae515573bad587a7dad2d 388cdd11f3c746690edc8e0f71289872c6180c60 dfff3db7763f55b0157f22d816d84c71bbc2dcad 793e71ee76acb49b215e31ee89e0c9cb52322811 92204134806ba4c41ba6cbc20ad2408015e7f3d5 c348da7c4c138c108695c5f309f62e87d0101eda 45abc1a5db60213bf94b5fb780dc6549ddd9103c 45a61cbf68a2459202b7eda4a01a56bfcb6be048 be63e8703c7354bdf0c767a771223b33ab2ad4f2 b13f801d6ff6f9fe5e58aa48fc31bd25ad0b072b b45ba35e350f2a62c6b06a637d707029bc99e559 fa48004af5ba58cfab38cd8ab5092719a5978509 fcc563a29bd91bd2a45b8f242eccaf37ab75b5b3 97cdb5be1ea84b5224f6353b425ea2503763df07 754a7f6c942268b2b604de072a3391ea4df91e57 b975a8a755b192f5980a14c46e745a92d3cdd3be e2a38216d2ff6dac8bc927603fdec1ba887b2da7 cd4c756fd5eece6b1d7723a407ead0ed1bf8a298 e663717cb13e49f4da21280bc2f455ddfeee782c cacde05ad3e8428ad0e16afcfdb715cb4b3d3165 567efa85c2194e45ae943c01c9dffe5b44e81c96 54fb0b9e95c398e8ba09bc7cdceca3f588f910b8 3b7bc307d5fd8e7b9c618a6454d32d59b83277d2 2beae8273b932505888dec35ae97bd8d74893272 0eb42087c7907f43c114cb57b5ff2cf2a52dfea4 b683978f1f4609e7a099ff8b36d7cac25e84cf7c a85d553d7608bf4c9ffe74546d32afe0275d7c69 86cfd4d4e8de1834607e977318eee4e0c6a9a565 593140dabd66f01aa0d606984ff684f7cb9c1eb1 956373230631929dfa9a36814a283666cb290ee0 0f8fd4548295e3a1516939d7f3bb912a8d7e4713 7ae08ef3a230978510e2722fc56b61ebbae9c6b7 Commits that altered the existing behavior but did so safely, in that they stopped accepting 'default' as a valid value for a property that was defined in the schema as only taking either 'yes' or 'no' and for which libvirt itself never produced the 'default' value: 9086ae4facfb91436c1d9e7daec9285156cb4eb8 931afa7d99b8ff6eb18a6aa402ed64b789197d30 38dc25989c50dad1f6f64aa038de8c2d1c008734 38d76cde5e90cbb59cd8c726f35646be1740c685 ee387289dd6c993bd2bcfdebcbad86a51fe36da8 550981ce9713ef82df49116c336a9f4bd0eedef4 b127e50290383dc26e8714ba866acc9f501d7af6 54635ea592859d110e87d19565ffabe24d2f0e2e 232c01ec4f650523ab5ff84cf38c4d8b55763052 bb94b3d28db909d43d83b3f2ab73aa3f881b5c95 3681a5393313eba7bfa8e8f763116efb9961c686 Commits that altered the existing behavior in a way that required some fixing afterwards: 0fe2d8dd335054fae38b46bbbac58a4662e1a1d0 Andrea Bolognani (9): conf: Don't pass PROP_NONZERO to virXMLPropTristateBool() conf: Use virTristateBoolToBool() more qemu: Format <allowReboot> conditionally util: Introduce virXMLPropTristateBoolAllowDefault() qemu: Accept <allowReboot value='default'/> qemu: Don't ignore XMLParseAllowReboot() errors conf: Restore error checking in VideoAccelDefParseXML() conf: Format managed property of hostdev-pci ports correctly network: Convert managed property of hostdev-pci ports correctly src/conf/domain_conf.c | 42 +++++++++++-------- src/conf/interface_conf.c | 2 +- src/conf/virnetworkportdef.c | 7 +++- src/libvirt_private.syms | 1 + src/network/bridge_driver.c | 2 +- src/qemu/qemu_domain.c | 19 +++++---- src/util/virxml.c | 18 ++++++++ src/util/virxml.h | 7 ++++ .../plug-hostdev-pci-unmanaged.xml | 12 ++++++ tests/virnetworkportxml2xmltest.c | 1 + 10 files changed, 83 insertions(+), 28 deletions(-) create mode 100644 tests/virnetworkportxml2xmldata/plug-hostdev-pci-unmanaged.xml -- 2.35.1
