[RFC PATCH 00/10] hw/misc/vmcoreinfo: Convert from QDev to plain Object
by Philippe Mathieu-Daudé 20 Dec '24

20 Dec '24

No reason for vmcoreinfo to be based on QDev, since it doesn't use any QDev API. Demote to plain Object. Since we can only register one type, introduce a new one for object: 'vmcore-info' (dash separator), keeping 'vmcoreinfo' device during the deprecation period.

[PATCH] qemu_capabilities: Avoid memleak in virQEMUCapsProbeFullDeprecatedProperties()
by Michal Privoznik 18 Dec '24

18 Dec '24

As one of its arguments, the virQEMUCapsProbeFullDeprecatedProperties() gets a pointer to GStrv (a string list), which it may eventually replace. It's single caller (virQEMUCapsProbeQMPHostCPU()) passes a string list indeed. Now, when replacing one string list with another plain g_free() is not enough as we need to free individual strings too. ==13573== 34 bytes in 8 blocks are definitely lost in loss record 271 of 576 ==13573== at 0x4844878: malloc (vg_replace_malloc.c:446) ==13573== by 0x51789D1: g_malloc (in /usr/lib64/libglib-2.0.so.0.7800.6) ==13573== by 0x5193E82: g_strdup (in /usr/lib64/libglib-2.0.so.0.7800.6) ==13573== by 0x4997F73: g_strdup_inline (gstrfuncs.h:321) ==13573== by 0x4997F73: virJSONValueArrayToStringList (virjson.c:1296) ==13573== by 0x5027CF7: qemuMonitorJSONParseCPUModelExpansion (qemu_monitor_json.c:5139) ==13573== by 0x50281C9: qemuMonitorJSONGetCPUModelExpansion (qemu_monitor_json.c:5245) ==13573== by 0x501044F: qemuMonitorGetCPUModelExpansion (qemu_monitor.c:3261) ==13573== by 0x4F190D0: virQEMUCapsProbeQMPHostCPU (qemu_capabilities.c:3227) ==13573== by 0x4F2145E: virQEMUCapsInitQMPMonitor (qemu_capabilities.c:5758) ==13573== by 0x10FFF8: testQemuCaps (qemucapabilitiestest.c:111) ==13573== by 0x110B53: virTestRun (testutils.c:143) ==13573== by 0x11063E: doCapsTest (qemucapabilitiestest.c:200) Fixes: 51c098347d7f2af9b4386ac0adc4431997d06f3d Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- src/qemu/qemu_capabilities.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index eda3e6a4df..27a283cff6 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -3176,7 +3176,7 @@ virQEMUCapsProbeFullDeprecatedProperties(qemuMonitor *mon, return -1; if (propsInfo && propsInfo->deprecated_props) { - g_free(*props); + g_strfreev(*props); *props = g_steal_pointer(&propsInfo->deprecated_props); } -- 2.45.2

[PATCH 0/3] src: fix virtnetworkd blocking (delaying) system shutdown
by Daniel P. Berrangé 18 Dec '24

18 Dec '24

We recently wired up inhibitors in the network driver to prevent auto-shutdown of libvirtd/virtnetworkd when virtual networks are active. This is to prevent the repeated re-creation of firewall rules which happens on daemon startup. Unfortunately we forgot that an inhibition on libvirt daemon shutdown *also* gets unconditionally turned into an inhibition on OS shutdown :-( In fixing this I realized this is actually the second such mistakes, because a few years ago we made the virtsecretd daemon inhibit when ephemeral secrets are present, and that really has no justification for blocking system shutdown either.

[PATCH] qemu: Enable I/O APIC even more frequently
by Michal Privoznik 18 Dec '24

18 Dec '24

In my previous commit v10.10.0-48-g2d222ecf6e I've made us enable I/O APIC when there is an IOMMU with EIM. This works well. What does not work is case when there's just an IOMMU without EIM but with 256+ vCPUS. Problem is that post parsing happens in two stages: general domain post parse (where qemuDomainDefEnableDefaultFeatures() is called) and then per device post parse (where qemuDomainIOMMUDefPostParse() is called). Now, in aforementioned case it is the device post parse phase where EIM is enabled but the code that would enable VIR_DOMAIN_FEATURE_IOAPIC has already run. To resolve this, make the domain post parse callback "foresee" the future enabling of EIM so that it can turn on I/O APIC beforehand.

[PATCH 0/3] Addng POWER11 cpu support
by Narayana Murty N 17 Dec '24

17 Dec '24

This patch series includes the changes needed to support POWER11 cpu and POWER11 host on libvirt. Patch also adds and updates the qemu caps with the latest qemu for the caps tests to include POWER11. Patch 0001: Add POWER11 cpu model support. Patch 0002: Add POWER11 host model support. Patch 0003: Add qemu and domain test capabilities test support. The respective patches for linux kernel and qemu already in upstream and links are provided below. Linux kernel patches: 1. Linux P11 support: commit id c2ed087ed35c ("powerpc: Add Power11 architected and raw mode") 2. Linux P11 KVM support: commit id 96e266e3bcd6 ("KVM: PPC: Book3S HV: Add Power11 capability support for Nested PAPR guests") Qemu patches: 3. Qemu P11 support: commit id 273db89bcaf4 ("ppc/pseries: Add Power11 cpu type) 4.

[PATCH v3 0/7] Allow Guest CPU Model with Deprecated Features Disabled
by Collin Walling 17 Dec '24

17 Dec '24

# Changelog v3 - added reviewed-by's on appropriate patches - split patch #4 into three: - domain API (libvirt-domain: introduce VIR_CONNECT_GET_DOMAIN_CAPABILITIES_DISABLE_DEPRECATED_FEATURES) - qemu (qemu_capabilities: filter deprecated features if requested) - virsh (virsh: add --disable-deprecated-features flag to domcapabilities) - Note: no functional change, patches were split based on changes to certain files - @Jiri, let me know if this is what you had in mind, I found it difficult to find a good reference - fixed deprecated_props array missing +1 in qemuJSONMonitor* functions - condensed cputypes schema for deprecated_features - added validation in qemu_process to check if QEMU cap is present - added qemuxmlconf tests - updated version tags to 11.0.0 v2 - rebased on latest master changes # Description Add support for libvirt to query and cache an array of deprecated CPU features (aka CPU properties) for the host-model. This data is queried via a full query-cpu-model-expansion and cached in the QEMU capabilities file. This model expansion will depend on the availability of the "deprecated-props" field resulting from a query-cpu-model-expansion command. Currently, only s390x supports this field. The purpose of these patches is to make it easy for users to create guests with a CPU model that will be compatible & migratable with future hardware. An updated host CPU model with deprecated features paired with the policy "disable" may be visable via an update to the virsh domcapabilities command with the --disable-deprecated-features flag. An example is shown below. Note: other CPU model queries (e.g. baseline and comparison) currently do not consider deprecated features, as their outputs do not consider feature policy. If implementation is desired, it will require a discussion on how these commands should report policies. Examples: virsh domcapabilities --disable-deprecated-features e.g. output (trimmed): <mode name='host-model' supported='yes'> <model fallback='forbid'>z14.2-base</model> <feature policy='require' name='aen'/> <feature policy='require' name='cmmnt'/> <feature policy='require' name='aefsi'/> <feature policy='require' name='diag318'/> <feature policy='require' name='mepoch'/> <feature
