[PATCH] vmx: Do not require all ID data for VMWare Distributed Switch
by Martin Kletzander 08 Jul '24

08 Jul '24

Similarly to commit 2482801608b8 we can safely ignore connectionId, portId and portgroupId in both XML and VMX as they are only a blind pass-through between XML and VMX and an ethernet without such parameters was spotted in the wild. On top of that even our documentation says the whole VMWare Distrubuted Switch configuration is a best-effort.

[PATCH] test_driver: support VIR_DOMAIN_AFFECT_LIVE in testUpdateDeviceFlags()
by John Levon 04 Jul '24

04 Jul '24

Pick up some more of the qemu_driver.c code so this function supports both CONFIG and LIVE updates. Note that qemuDomainUpdateDeviceFlags() passed vm->def to virDomainDeviceDefParse() for the VIR_DOMAIN_AFFECT_CONFIG case, which is technically incorrect; in the test driver code we'll fix this.

[PATCH] conf: Fix out-of-bounds write during cleanup of virDomainNumaDefNodeDistanceParseXML
by Rayhan Faizel 04 Jul '24

04 Jul '24

mem_nodes[i].ndistances is written outside the loop causing an out-of-bounds write leading to heap corruption. While we are at it, the entire cleanup portion can be removed as it can be handled in virDomainNumaFree. One instance of VIR_FREE is also removed and replaced with g_autofree. This patch also adds a testcase which would be picked up by ASAN, if this portion regresses.

Current ch driver supports restore only for domains without any network configuration defined. This was because libvirt explicitly passes network fds and CH did not had support to restore with new net FDS. This support has been added recently, https://github.com/cloud-hypervisor/cloud-hypervisor/pull/6402 The changes in this patch series includes moving to socket communication for restore api, create new net fds and pass them via SCM_RIGHTS to CH.

[PATCH v2] tests: Move domainEventState initialization to qemuTestDriverInit
by Rayhan Faizel 04 Jul '24

04 Jul '24

Under the test environment, driver->domainEventState is uninitialized. If a disk gets dropped, it will attempt to queue an event which will cause a segmentation fault. This crash does not occur during normal use. This patch moves driver->domainEventState initialization from qemuhotplugtest to qemuTestDriverInit in testutilsqemu (Credit goes to Michal Privoznik as he had already provided the diff). An additional test case is added to test dropping of disks with startupPolicy set as optional.

[PATCH v1] security_manager: Ensure top lock is acquired before nested locks
by hongmianquan 04 Jul '24

04 Jul '24

We need to ensure top lock is acquired before nested lock. Otherwise deadlock issues may arise. We have the stack security driver, which internally manages other security drivers, we call them "top" and "nested". We call virSecurityStackPreFork() to lock the top one, and it also locks and then unlocks the nested drivers prior to fork. Then in qemuSecurityPostFork(), it unlocks the top one, but not the nested ones. Thus, if one of the nested drivers ("dac" or "selinux") is still locked, it will cause a deadlock. We discovered this case: the nested list obtained through the qemuSecurityGetNested() will be locked for subsequent use, such as in virQEMUDriverCreateCapabilities(), where the nested list is locked using qemuSecurityGetDOI, but the top one is not locked beforehand. The problem stack is as follows: libvirtd thread1 libvirtd thread2 child libvirtd | | | | | | virsh capabilities qemuProcessLanuch | | | | | lock top | | | | lock nested | | | | | | fork------------------->|(held nested lock) | | | | | | unlock nested unlock top unlock top | | qemuSecuritySetSocketLabel | | lock nested (deadlock) In this commit, we ensure that the top lock is acquired before the nested lock, so during fork, it's not possible for another task to acquire the nested lock.

Re: [PATCH v1] security_manager: Ensure top lock is acquired before nested locks
by ByteDance 03 Jul '24

Yes, we have recently encountered this issue, and it is exactly the same as the scenario described in the bug report. We investigated the code and found this potential problem. The issue occurs when collecting information through the ‘virsh capabilities' while concurrently creating vm. The higher the frequency and concurrency, the more likely the issue will reproduce. We believe this is a very rare bug; our environment has been running for three years, and we've only encountered this issue once. To successfully reproduce the problem, we constructed a test case by adding a sleep between the lock nested and unlock. But we still need to try to fix this issue, even though the probability is very low.

[PATCH v2] conf: Fix rawio/sgio checks for non-scsi hostdev devices
by Rayhan Faizel 03 Jul '24

03 Jul '24

The current hostdev parsing logic sets rawio or sgio even if the hostdev type is not 'scsi'. The rawio field in virDomainHostdevSubsysSCSI overlaps with wwpn field in virDomainHostdevSubsysSCSIVHost, consequently setting a bogus pointer value such as 0x1 or 0x2 from virDomainHostdevSubsysSCSIVHost's point of view. This leads to a segmentation fault when it attempts to free wwpn. While setting sgio does not appear to crash, it shares the same flawed logic as setting rawio. Instead, we ensure these are set only after the hostdev type check succeeds. This patch also adds two test cases to exercise both scenarios.

[PATCH] qemu_domain: Check if driver->domainEventState is NULL
by Rayhan Faizel 03 Jul '24

03 Jul '24

Under the test environment, driver->domainEventState is uninitialized. If a disk gets dropped, it will attempt to queue an event which will cause a segmentation fault. This crash does not occur during normal use. This patch adds a quick check to ensure driver->domainEventState is not NULL along with a testcase exercising the dropping of disks with startupPolicy set as 'optional'.

[PATCH v2 00/14] hw: define and enforce a standard lifecycle for versioned machines
by Daniel P. Berrangé 01 Jul '24

01 Jul '24

Thomas proposed a new deprecation and removal policy for versioned machine types that would see them liable for deletion after 6 years: https://lists.nongnu.org/archive/html/qemu-devel/2024-04/msg04683.html This suggest was met with broad approval, however, I suggested that we could take it further and actually mark them deprecated sooner, at the 3 year timeframe, and also fully automate the enablement of the runtime deprecation warning without developer intervention on every release cycle. This series implements my suggestions. The first patch introduces some helper macros and documents a standard code pattern for defining versioned machine types across targets. The next 6 patches convert existing targets with versioned machine types (arm, s390x, ppc, m68k, i386) to use the new helper macros and code patterns. A further patch introduces some helper macros for automating the handling of deprecation and deletion of versioned machine types. Two more patches then enable the deprecation and deletion logic across all versioned machines Finally we do some cleanup and document the new policy. ........a tangent about VERSION file handling....... One oddity here, is that during the development and release candidate phases the automatic logic in this series has an off-by-1 error. This is because when we, for example, add the "9.1" machine type versions, the VERSION file is still reporting '9.0.50', and then '9.0.9{1,2,3,4}'. IOW, during development and in rc candidates, we fail to deprecate and delete 1 machine type. We should already have deprecated the 6.1 machine types, but the most recently deprecated is 6.0. This is pretty harmless since the final release does the right thing. I wonder, however, whether we would benefit from changing how we update the VERSION file. eg instead of re-using the micro digit to indicate a dev or rc snapshot, represent those explicitly. eg "9.1.0-dev" and "9.1.0-rc1", "9.1.0-rc2", etc in VERSION. We don't use the full QEMU_VERSION in the code in all that many places. It appears in some help messages for command line tools, and in QMP query-version response, and in a few other misc places. At a glance it appears all of those places would easily handle a tagged version. For release candidates in particular I think it would be saner to show the user the actual version the release is about to become, rather than the previous release's version. This would make the reported version match the rc tarball naming too which would be nice. Anyway, this isn't a blocker for this machine type versioning proposal, just a thought.... Changed in v2: - Various docs improvements and minor fixes from original review - Rebased and resolved conflicts with Philippe's merged series Daniel P. Berrangé (14): include/hw: add helpers for defining versioned machine types hw/arm: convert 'virt' machine definitions to use new macros hw/s390x: convert 'ccw' machine definitions to use new macros hw/ppc: convert 'spapr' machine definitions to use new macros hw/m68k: convert 'virt' machine definitions to use new macros hw/i386: convert 'i440fx' machine definitions to use new macros hw/i386: convert 'q35' machine definitions to use new macros include/hw: add macros for deprecation & removal of versioned machines include/hw: temporarily disable deletion of versioned machine types hw: set deprecation info for all versioned machine types hw: skip registration of outdated versioned machine types hw/ppc: remove obsolete manual deprecation reason string of spapr machines hw/i386: remove obsolete manual deprecation reason string of i440fx machines docs: document special exception for machine type deprecation & removal docs/about/deprecated.rst | 13 ++ hw/arm/virt.c | 30 ++-- hw/i386/pc_piix.c | 220 ++++++++++++--------------- hw/i386/pc_q35.c | 215 +++++++++++--------------- hw/m68k/virt.c | 53 ++++--- hw/ppc/spapr.c | 96 ++++++------ hw/s390x/s390-virtio-ccw.c | 98 ++++++------ include/hw/boards.h | 298 +++++++++++++++++++++++++++++++++++++ include/hw/i386/pc.h | 28 ++++ 9 files changed, 681 insertions(+), 370 deletions(-) -- 2.43.0

[PATCH] qemucapabilitiestest: Add 'qemu_9.0.0.sparc' capabilities from TCG
by Peter Krempa 01 Jul '24

01 Jul '24

As I don't have a sparc machine handy add emulated capabilities. This patch is in preparation for bumping minimum qemu version beyond the oldest 'sparc' caps we currently have.

Release of libvirt-10.5.0
by Jiri Denemark 01 Jul '24

01 Jul '24

The 10.5.0 release of both libvirt and libvirt-python is tagged and signed tarballs 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 * Introduce SEV-SNP support SEV-SNP is introduced as another type of ``<launchSecurity/>``. Its support is reported in both domain capabilities and ``virt-host-validate``. * Improvements * tools: virt-pki-validate has been rewritten in C The ``virt-pki-validate`` shell script has been rewritten as a C program, providing an output format that matches ``virt-host-validate``, removing the dependency on ``certtool`` and providing more comprehensive checks of the certificate properties. * qemu: implement iommu coldplug/unplug The ``<iommu/>`` device can be now cold plugged and/or cold unplugged. * Pass shutoff reason to release hook Sometimes in release hook it is useful to know if the VM shutdown was graceful or not. This is especially useful to do cleanup based on the VM shutdown failure reason in release hook. Starting with this release the last argument 'extra' is used to pass VM shutoff reason in the call to release hook. * nodedev: improve DASD detection In newer DASD driver versions the ID_TYPE tag is supported. This tag is missing after a system reboot but when the ccw device is set offline and online the tag is included. To fix this version independently we need to check if a device detected as type disk is actually a DASD to maintain the node object consistency and not end up with multiple node objects for DASDs. * Bug fixes * remote_daemon_dispatch: Unref sasl session when closing client connection A memory leak was identified when a client started SASL but then suddenly closed connection. This is now fixed. * qemu: Fix migration with disabled vmx-* CPU features Migrating a domain with some vmx-* CPU features marked as disabled could have failed as the destination would incorrectly expect those features to be enabled after starting QEMU. * qemu: Fix ``libvirtd``/``virtqemud`` crash when VM shuts down during migration The libvirt daemon could crash when a VM was shut down while being migrated to another host. Enjoy. Jirka

[PATCH 0/8] ch: support restore with network devices
by Purna Pavan Chandra 28 Jun '24

28 Jun '24

Current ch driver supports restore only for domains without any network configuration defined. This was because libvirt explicitly passes network fds and CH did not had support to restore with new net FDS. This support has been added recently, https://github.com/cloud-hypervisor/cloud-hypervisor/pull/6402 The changes in this patch series majorly include moving to socket communication for restore api, create new net fds and pass them via SCM_RIGHTS to CH. Purna Pavan Chandra (8): ch: report response message instead of just code ch: Pass net ids explicitly during vm creation ch: refactor chProcessAddNetworkDevices ch: poll with -1 in chSocketRecv ch: use monitor socket fd to send restore request ch: refactor virCHMonitorSaveVM ch: support restore with net devices ch: kill CH process if restore fails src/ch/ch_driver.c | 9 +- src/ch/ch_monitor.c | 62 +++++++----- src/ch/ch_monitor.h | 6 +- src/ch/ch_process.c | 225 ++++++++++++++++++++++++++++++++++---------- 4 files changed, 223 insertions(+), 79 deletions(-) -- 2.34.1

[PATCH 0/8] Report 'passt' support in domain capabilities
by Michal Privoznik 28 Jun '24

28 Jun '24

There are some distributions that consider switching from SLIRP to just passt. While libvirt wires no defaults and leaves this kind of decisions onto upper layers, it can help mgmt apps do the decision by reporting passt support in domain capabilities. Michal Prívozník (8): libvirt_private.syms: Export virDomainNetBackendType enum handlers qemu_capabilities: Introduce QEMU_CAPS_NETDEV_USER qemu_validate: Validate net backends against QEMU caps domain_capabilities: Introduce netdev capabilities qemu_capabilities: Fill supported net backend types conf: Accept 'default' backend type for <interface type='user'/> qemu_validate: Use domaincaps to validate supported net backend type qemu_domain: Set 'passt' net backend if 'default' is unsupported docs/formatdomaincaps.rst | 25 +++++++++++++++++++ src/conf/domain_capabilities.c | 13 ++++++++++

[PATCH] qemu: fix switchover-ack regression for old qemu
by Jon Kohler 28 Jun '24

28 Jun '24

When enabling switchover-ack on qemu from libvirt, the .party value was set to both source and target; however, qemuMigrationParamsCheck() only takes that into account to validate that the remote side of the migration supports the flag if it is marked optional or auto/always on. In the case of switchover-ack, when enabled on only the dst and not the src, the migration will fail if the src qemu does not support switchover-ack, as the dst qemu will issue a switchover-ack msg: qemu/migration/savevm.c -> loadvm_process_command -> migrate_send_rp_switchover_ack(mis) -> migrate_send_rp_message(mis, MIG_RP_MSG_SWITCHOVER_ACK, 0, NULL) Since the src qemu doesn't understand messages with header_type == MIG_RP_MSG_SWITCHOVER_ACK, qemu will kill the migration with error: qemu-kvm: RP: Received invalid message 0x0007 length 0x0000 qemu-kvm: Unable to write to socket: Bad file descriptor Looking at the original commit [1] for optional migration capabilities, it seems that the spirit of optional handling was to enhance a given existing capability where possible. Given that switchover-ack exclusively depends on return-path, adding it as optional to that cap feels right.

[RFC PATCH v3 0/6] Added virtio-net RSS with eBPF support.
by Andrew Melnychenko 27 Jun '24

27 Jun '24

This series of rfc patches adds support for loading the RSS eBPF program and passing it to the QEMU. Comments and suggestions would be useful. QEMU with vhost may work with RSS through eBPF. To load eBPF, the capabilities required that Libvirt may provide. eBPF program and maps may be unique for particular QEMU and Libvirt retrieves eBPF through qapi. For now, there is only "RSS" eBPF object in QEMU, in the future, there may be another one(g.e. network filters). That's why in Libvirt added logic to load and store any eBPF object that QEMU provides using qapi schema. One of the reasons why this series of patches is in RFC are tests. To this series of patches, the tests were added. For now, the tests are synthetic, the proper "reply" file should be generated with a new "caps" file. Currently, there are changes in caps-9.0.0* files. There was added support for ebpf_rss_fds feature, and request-ebpf command. Also, there was added new config for qemuConfig - allowEBPF. This config allows to enable/disable eBPF blob loading explicitly. This is required for qemuxmlconf tests - where some test expects that RSS would not support eBPF. So, overall, the tests are required for review, comment, and discussion how we want them to be implemented in the future. For virtio-net RSS, the document has not changed. ``` <interface type="network"> <model type="virtio"/> <driver queues="4" rss="on" rss_hash_report="off"/> <interface type="network"> ``` Simplified routine for RSS: * Libvirt retrieves eBPF "RSS" and load it. * Libvirt passes file descriptors to virtio-net with property "ebpf_rss_fds" ("rss" property should be "on" too). * if fds was provided - QEMU using eBPF RSS implementation. * if fds was not provided - QEMU tries to load eBPF RSS in own context and use it. * if eBPF RSS was not loaded - QEMU uses "in-qemu" RSS(vhost not supported). Changes since RFC v2: * refactored and rebased. * applied changes according to the Qemu. * added basic test. Changes since RFC v1: * changed eBPF format saved in the XML cache. * refactored and checked with syntax test. * refactored patch hunks.

[PATCH v2] security_manager: Ensure top lock is acquired before nested locks
by hongmianquan 27 Jun '24

27 Jun '24

Fix libvirtd hang since fork() was called while another thread had security manager locked. We have the stack security driver, which internally manages other security drivers, just call them "top" and "nested". We call virSecurityStackPreFork() to lock the top one, and it also locks and then unlocks the nested drivers prior to fork. Then in qemuSecurityPostFork(), it unlocks the top one, but not the nested ones. Thus, if one of the nested drivers ("dac" or "selinux") is still locked, it will cause a deadlock. We discovered this case: the nested list obtained through the qemuSecurityGetNested() will be locked for subsequent use, such as in virQEMUDriverCreateCapabilities(), where the nested list is locked using qemuSecurityGetDOI, but the top one is not locked beforehand. The problem stack is as follows: libvirtd thread1 libvirtd thread2 child libvirtd | | | | | | virsh capabilities qemuProcessLanuch | | | | | lock top | | | | lock nested | | | | | | fork------------------->|(nested lock held by thread1) | | | | | | unlock nested unlock top unlock top | | qemuSecuritySetSocketLabel | | lock nested (deadlock) In this commit, we ensure that the top lock is acquired before the nested lock, so during fork, it's not possible for another task to acquire the nested lock.

[PATCH 0/2] qemu_command: Enable sev-guest.legacy-vm-type when possible
by Michal Privoznik 25 Jun '24

*** IMPORTANT *** There's a competing patch sent to qemu-devel which when merged renders these patches unnecessary: https://mail.gnu.org/archive/html/qemu-devel/2024-06/msg02776.html But I accumulated this change whilst working on previous patches that enabled SEV SNP and figured might as well send them if QEMU patch doesn't make it in time for our release.

[PATCH v2] qemu: add support for qemu switchover-ack
by Jon Kohler 25 Jun '24

25 Jun '24

Add plumbing for QEMU's switchover-ack migration capability, which helps lower the downtime during VFIO migrations. This capability is enabled by default as long as both the source and destination support it. Note: switchover-ack depends on the return path capability, so this may not be used when VIR_MIGRATE_TUNNELLED flag is set. Extensive details about the qemu switchover-ack implementation are available in the qemu series v6 cover letter [1] where the highlight is the extreme reduction in guest visible downtime. In addition to the original test results below, I saw a roughly ~20% reduction in downtime for VFIO VGPU devices at minimum. === Test results === The below table shows the downtime of two identical migrations. In the first migration swithcover ack is disabled and in the second it is enabled. The migrated VM is assigned with a mlx5 VFIO device which has 300MB of device data to be migrated. +----------------------+-----------------------+----------+ | Switchover ack | VFIO device data size | Downtime | +----------------------+-----------------------+----------+ | Disabled | 300MB | 1900ms | | Enabled | 300MB | 420ms | +----------------------+-----------------------+----------+ Switchover ack gives a roughly 4.5 times improvement in downtime. The 1480ms difference is time that is used for resource allocation for the VFIO device in the destination. Without switchover ack, this time is spent when the source VM is stopped and thus the downtime is much higher. With switchover ack, the time is spent when the source VM is still running.

[PATCH] qemu: Fix migration with disabled vmx-* CPU features
by Jiri Denemark 25 Jun '24

25 Jun '24

When starting a domain on a host which lacks a vmx-* CPU feature which is expected to be enabled by the CPU model specified in the domain XML, libvirt properly marks such feature as disabled in the active domain XML. But migrating the domain to a similar host which lacks the same vmx-* feature will fail with libvirt reporting the feature as missing. This is because of a bug in the hack ensuring backward compatibility libvirt running on the destination thinks the missing feature is expected to be enabled. https://issues.redhat.com/browse/RHEL-40899 Fixes: v10.1.0-85-g5fbfa5ab8a Signed-off-by: Jiri Denemark <jdenemar(a)redhat.com> --- src/cpu/cpu_x86.c | 44 +++++++++++++++++++++++++++----------------- 1 file changed, 27 insertions(+), 17 deletions(-) diff --git a/src/cpu/cpu_x86.c b/src/cpu/cpu_x86.c index 7a70eed9e7..fcbce0ec46 100644 --- a/src/cpu/cpu_x86.c +++ b/src/cpu/cpu_x86.c @@ -3021,10 +3021,7 @@ virCPUx86UpdateLive(virCPUDef *cpu, if (!(map = virCPUx86GetMap())) return -1; - if (!(model = x86ModelFromCPU(cpu, map, -1))) - return -1; - - if (hostPassthrough && + if (!(model = x86ModelFromCPU(cpu, map, -1)) || !(modelDisabled = x86ModelFromCPU(cpu, map, VIR_CPU_FEATURE_DISABLE))) return -1; @@ -3037,12 +3034,19 @@ virCPUx86UpdateLive(virCPUDef *cpu, for (i = 0; i < map->nfeatures; i++) { virCPUx86Feature *feature = map->features[i]; virCPUFeaturePolicy expected = VIR_CPU_FEATURE_LAST; + bool explicit = false; + bool ignore = false; - if (x86DataIsSubset(&model->data, &feature->data)) + if (x86DataIsSubset(&model->data, &feature->data)) { + explicit = true; expected = VIR_CPU_FEATURE_REQUIRE; - else if (!hostPassthrough || - x86DataIsSubset(&modelDisabled->data, &feature->data)) + } else if (x86DataIsSubset(&modelDisabled->data, &feature->data)) { + explicit = true; + expected = VIR_CPU_FEATURE_DISABLE; + } else if (!hostPassthrough) { + /* implicitly disabled */ expected = VIR_CPU_FEATURE_DISABLE; + } if (x86DataIsSubset(&enabled, &feature->data) && x86DataIsSubset(&disabled, &feature->data)) { @@ -3052,30 +3056,36 @@ virCPUx86UpdateLive(virCPUDef *cpu, return -1; } + /* Features enabled or disabled by the hypervisor are ignored by + * check='full' in case they were added to the model later and not + * explicitly mentioned in the CPU definition.

Without switchover ack, this time is spent when the source VM is stopped and thus the downtime is much higher. With switchover ack, the time is spent when the source VM is still running.

[PATCH] network: add more firewall test cases
by Laine Stump 24 Jun '24

24 Jun '24

This patch adds some previously missing test cases that test for proper firewall rule creation when the following are included in the network definition: * <forward dev='blah'> * no forward element (an "isolated" network) * nat port range when only ipv4 is nat-ed * nat port range when both ipv4 & ipv6 are nated Signed-off-by: Laine Stump <laine(a)redhat.com> --- If you ack this, please also push it, as I'm on vacation and only sporadically connected. .../forward-dev-linux.iptables | 154 +++++++ .../forward-dev-linux.nftables | 158 +++++++ tests/networkxml2firewalldata/forward-dev.xml | 10 +

[PATCH] tests: fix broken nftables test data so that individual tests are successful
by Laine Stump 24 Jun '24

24 Jun '24

When the chain names and table name used by the nftables firewall backend were changed in commit 958aa7f274904eb8e4678a43eac845044f0dcc38, I forgot to change the test data file base.nftables, which has the extra "list" and "add chain/table" commands that are generated for the first test case of networkxml2firewalltest.c. When the full set of tests is run, the first test will be an iptables test case, so those extra commands won't be added to any of the nftables cases, and so the data in base.nftables never matches, and the tests are all successful. However, if the test are limited with, e.g. VIR_TEST_RANGE=2 (test #2 will be the nftables version of the 1st test case), then the commands to add nftables table/chains *will* be generated in the test output, and so the test will fail. Because I was only running the entire test series after the initial commits of nftables tests, I didn't notice this. Until now. base.nftables has now been updated to reflect the current names for chains/table, and running individual test cases is once again successful.

[RFC PATCH 0/1] support deprecated-props from query-cpu-model-expansion
by Collin Walling 19 Jun '24

19 Jun '24

Overview ======== QEMU will soon support reporting an optional array of deprecated features for an expanded CPU model via the query-cpu-model-expansion command. The intended use of this data is to make it easier for a user to define a CPU model with features flagged as deprecated set to disabled, thus rendering the guest migratable to future hardware that will out-right drop support for said features. Attached to this cover letter is only half of the bigger picture. I've updated the CPU model expansion ABI to parse the new array (if it's available) and store the result in a string list within the qemuMonitorCPUModelInfo struct. I also propose an approach on how to store/retrieve the list of deprecated features in the qemuCaps cache file. All feedback on this patch is certainly welcome. Please note: I do not provide any updates to the respective qemuCaps tests right now. The main goal of this post is to discuss the other half of the design: reporting and enabling a CPU model with deprecated features disabled. I believe the ideal solution involves a way for the user to easily configure their guest with this new data. Two ideas I currently have are outlined below. Other approaches are encouraged. Notes ===== - In my example below, I am running on a z14.2 machine. - The features that are flagged as deprecated for this model are: bpb, csske, cte, te. - The discussion regarding the QEMU changes can be found here: https://mail.gnu.org/archive/html/qemu-devel/2024-04/msg04605.html Example of Desired Changes ========================== Here is what I'd like the resulting guest's transient XML to look like for the <cpu> section (I have trimmed the features list for brevity): ... <cpu mode='custom' match='exact' check='partial'> <model fallback='forbid'>z14.2-base</model> <feature policy='require' name='aen'/> <feature policy='require' name='cmmnt'/> <feature policy='require' name='aefsi'/> ... <feature policy='disable' name='cte'/> *** <feature policy='require' name='ais'/> <feature policy='disable' name='bpb'/> *** <feature policy='require' name='ctop'/> <feature policy='require' name='gs'/> <feature policy='require' name='ppa15'/> <feature policy='require' name='zpci'/> <feature policy='require' name='sea_esop2'/> <feature policy='disable' name='te'/> *** <feature policy='require' name='cmm'/> <feature policy='disable' name='csske'/> *** </cpu> ... Ideas ===== New Host CPU Model ------------------ Create a new CPU model that is a mirror of the host CPU model with deprecated features turned off. Let's call this model "host-recommended". A user may define this model in the guest XML as they would any other CPU model: <cpu mode='host-recommended' check='partial'/> Just as how host-model works, anything defined nested in the <cpu> tag will be ignored. This model could potentially be listed in the domcapabilities output after the host-model: <cpu> <mode name='host-passthrough' supported='yes'> ... </mode> ... <mode name='host-model' supported='yes'> ... </mode> <mode name='host-recommended' supported='yes'> ... <feature policy='disable' name='cte'/> <feature policy='require' name='ais'/> <feature policy='disable' name='bpb'/> <feature policy='require' name='ctop'/> <feature policy='require' name='gs'/> <feature policy='require' name='ppa15'/> <feature policy='require' name='zpci'/> <feature policy='require' name='sea_esop2'/> <feature policy='disable' name='te'/> <feature policy='require' name='cmm'/> <feature policy='disable' name='csske'/> </cpu> New Nested Element Under <cpu> ------------------------------ Create a new optional XML element nested under the <cpu> tag that may be used to disable deprecated features. This approach is more explicit compared to creating a new CPU model, and allows the user to disable these features when defining a specific model other than host-model. Here is an example of what the guest's defined XML for the CPU could look like: <cpu mode='host-model' check='partial'> <deprecated_features>off</deprecated_features> </cpu> However, a conflict arises with this approach: parameter priority. It would need to be discussed what the expected behavior should be if a user defines a guest with both a mode to disable deprecated features and any deprecated features listed with the 'require' policy, e.g.: <cpu mode='custom' match='exact' check='partial'> <model fallback='allow'>z13.2-base</model>  <deprecated_features>off</deprecated_features> <feature policy='require' name='csske'/> </cpu> Another conflict is setting this option to "on" would have no effect on the CPU model (I can't think of a reason why someone would want to explicitly enable these features). This may not communicate well to the user. To report these features, a <deprecatedProperties> tag could be added to the domcapabilities output using the same format I use in my proposed patch for the qemu capabilities file: <cpu> <mode name='host-passthrough' supported='yes'> ... </mode> ... <mode name='host-model' supported='yes'> ... </mode> <deprecatedProperties> <property name='bpb'/> <property name='te'/> <property name='cte'/> <property name='csske'/> </deprecatedProperties> </cpu> Please let me know your thoughts. Once an approach is agreed upon, I will begin development.
