[PATCH] virtio-blk: drop deprecated scsi=on|off property
by Stefan Hajnoczi 04 May '21

04 May '21

The scsi=on|off property was deprecated in QEMU 5.0 and can be removed completely at this point. Drop the scsi=on|off option. It was only available on Legacy virtio-blk devices. Linux v5.6 already dropped support for it. Remove the hw_compat_2_4[] property assignment since scsi=on|off no longer exists. Old guests with Legacy virtio-blk devices no longer see the SCSI host features bit. Live migrating old guests from an old QEMU with the SCSI feature bit enabled will fail with "Features 0x... unsupported. Allowed features: 0x...". We've followed the QEMU deprecation policy so users have been warned... I have tested that libvirt still works when the property is absent. It no longer adds scsi=on|off to the command-line.

[libvirt PATCH 0/6] Enable sanitizers
by Tim Wiederhake 04 May '21

04 May '21

This series enables and adds AddressSanitizer and UndefinedBehaviorSanitizer builds to the CI. See: https://clang.llvm.org/docs/AddressSanitizer.html and https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html These sanitizers already found some issues in libvirt, e.g. 4eb7c621985dad4de911ec394ac628bd1a5b29ab, 1294de209cee6643511265c7e2d4283c047cf652, 8b8c91f487592c6c067847ca59dde405ca17573f, or 1c34211c22de28127a509edbf2cf2f44cb0d891e. There exist two more relevant sanitizers, ThreadSanitizer and MemorySanitizer. Unfortunately, those two require an instrumented build of all dependencies, including libc, to work correctly. Note that clang and gcc have different implementations of these sanitizers, hence the introduction of two new jobs to the CI. The latter one issues a warning about the use of LD_PRELOAD in `virTestMain`, which in this particular case can be safely ignored by setting `ASAN_OPTIONS` to verify_asan_link_order=0` for the gcc build. Cheers, Tim Tim Wiederhake (6): meson: Allow larger stack frames when instrumenting meson: Allow undefined symbols when sanitizers are enabled tests: virfilemock: realpath: Allow non-null second parameter tests: openvzutilstest: Remove duplicate linking with libvirt_openvz.a virt-aa-helper: Remove duplicate linking with src/datatypes.o ci: Enable address and undefined behavior sanitizers .gitlab-ci.yml | 35 +++++++++++++++++++++++++++++++++++ build-aux/syntax-check.mk | 2 +- meson.build | 8 +++++++- src/libvirt_openvz.syms | 2 ++ src/security/meson.build | 1 - tests/meson.build | 2 +- tests/virfilemock.c | 12 ++++++------ 7 files changed, 52 insertions(+), 10 deletions(-) -- 2.26.3

[PATCH 1/2] qcow2: Prohibit backing file changes in 'qemu-img amend'

This was deprecated back in bc5ee6da7 (qcow2: Deprecate use of qemu-img amend to change backing file), and no one in the meantime has given any reasons why it should be supported. Time to make change attempts a hard error (but for convenience, specifying the _same_ backing chain is not forbidden). Update a couple of iotests to match.

[PATCH] Deprecate pmem=on with non-DAX capable backend file
by Igor Mammedov 03 May '21

03 May '21

It is not safe to pretend that emulated NVDIMM supports persistence while backend actually failed to enable it and used non-persistent mapping as fall back. Instead of falling-back, QEMU should be more strict and error out with clear message that it's not supported. So if user asks for persistence (pmem=on), they should store backing file on NVDIMM.

[PATCH v2] meson: Declare GLIB_VERSION_* macros at configure
by Michal Privoznik 03 May '21

03 May '21

So far we have three places where glib version is recorded: meson.build and then in config.h. The latter is so well hidden that it's easy to miss when bumping minimal glib version in the former. With a bit of python^Wmeson string magic GLIB_VERSION_MIN_REQUIRED and GLIB_VERSION_MAX_ALLOWED macros can be defined to match glib_version from meson.build.

Release of libvirt-7.3.0
by Jiri Denemark 03 May '21

03 May '21

The 7.3.0 release of both libvirt and libvirt-python is tagged and signed tarballs and source RPMs are available at https://libvirt.org/sources/ https://libvirt.org/sources/python/ Thanks everybody who helped with this release by sending patches, reviewing, testing, or providing any other feedback. Your work is greatly appreciated. * New features * xen: Support domains with more than 4TB The xen driver now supports domains with more than 4TB of memory with xen >= 4.13. * qemu: add socket for virtiofs filesystems Libvirt now supports ``filesystem`` devices that connect to a ``virtiofsd`` daemon launched outside of libvirtd, via the ``socket`` attribute of the ``source`` element. * nodedev: Add ability to manage persistent mediated devices Persistent mediated devices can now be managed with libvirt. ``virNodeDeviceDefineXML()`` defines a new device, ``virNodeDeviceUndefine()`` removes an existing definition, and ``virNodeDeviceCreate()`` starts a device definition that is currently inactive. Corresponding virsh commands ``nodedev-define``, ``nodedev-undefine``, and ``nodedev-start`` were also added. ``nodedev-list`` only lists active devices by default. Inactive device definitions can be shown with the new ``--inactive`` and ``--all`` flags. * qemu: Allow use of qemu's ``-compat`` option Curious developers or testers now can enable certain ``-compat`` modes which allow to notice use of deprecated commands and options as qemu will use the selected method to notify the user. The new behaviour can be requested using either the ``deprecation_behavior`` option in ``qemu.conf`` for all VMs or using ``<qemu:deprecation behavior='...'/>`` in the VM XML. * Improvements * virsh: Improve errors with ``virsh snapshot-create-as`` The XML document constructed by virsh was forced through XML schema validation which yielded unintelligible error messages in cases such as when the path to the new image did not start with a slash. XML documents are no longer validated as the XML parser actually has better error messages which allow users to figure the problem out quickly. * qemu: Terminate backing store when doing a full-chain block pull When pulling everything into the overlay image the chain can be terminated since we know that it won't depend on any backing image and thus can prevent attempts to probe the backing chain. * qemu: Expose disk serial in virDomainGetGuestInfo() The ``virDomainGetGuestInfo()`` reports disk serial number among with other disk information. * Bug fixes * qemu: Fix crash of libvirt on full block pull of a disk When the persistent definition contains a compatible disk (meaning the definition of the running and persistent config match) a block pull job would leave a dangling pointer in the config definition which resulted in a crash. * qemu: Use proper job cancelling command Libvirt's API contract for aborting a block copy job in 'ready' state declares that the destination image of the copy will contain a consistent image of the disk from the time when the block job was aborted. This requires that libvirt uses the proper cancelling qemu command to ensure that the data is consistent which was not the case. * qemu: Don't attempt storage migration when there are no migratable disks Due to a logic bug introduced in the previous release libvirt would attempt to migrate disks in case when no disks are selected/eligible for migration. * qemu: Fix very rare race when two block job 'ready' events are delivered In certain high-load scenarios, qemu might deliver the 'ready' event twice and if it's delivered when pivoting to the destination during a block copy job, libvirt would get confused and execute the code as if the job were aborted. * lxc: Fix container destroy with CGroupsV2 When an LXC container was started and the host used CGroupsV2 it might have had created nested controllers under the container's scope. Libvirt was unaware and thus destroying the container failed with a cryptic error: ``failed to get cgroup backend for 'pathOfController'``. The CGroup removal code was reworked and is now capable of dealing with such scenario. * bash-completion: Fix argument passing to $1 Due to a bug in bash completion script, the auto completion did not work properly when a connection URI or read only flag were specified on ``virsh`` or ``virt-admin`` command line. Enjoy. Jirka

[PATCH for 7.3] conf: Fix heap corruption when hot-adding a lease
by Peter Krempa 03 May '21

03 May '21

Commit 28a86993162f7d2f ( v6.9.0-179-g28a8699316 ) incorrectly replaced VIR_EXPAND_N by g_renew. VIR_EXPAND_N has these two extra effects apart from reallocating memory: 1) The newly allocated memory is zeroed out 2) The number of elements in the array which is passed to VIR_EXPAND_N is increased. This comes into play when used with virDomainLeaseInsertPreAlloced, which expects that the array element count already includes the space for the added 'lease', by plainly just assigning to 'leases[nleases - 1' Since g_renew does not increase the number of elements in the array any existing code which calls virDomainLeaseInsertPreAlloced thus either overwrites a lease definition or corrupts the heap if there are no leases to start with. To preserve existing functionality we revert the code back to using VIR_EXPAND_N which at this point doesn't return any value, so other commits don't need to be reverted.

[libvirt PATCH] virnetdevbridge: Ignore EEXIST when adding an entry to fdb
by Jiri Denemark 03 May '21

03 May '21

When updating entries in a bridge forwarding database (i.e., when macTableManager='libvirt' is configured for the bridge), we may end up in a situation when the entry we want to add is already present. Let's just ignore the error in such a case. This fixes an error to resume a domain when fdb entries were not properly removed when the domain was paused: virsh # resume test error: Failed to resume domain test error: error adding fdb entry for vnet2: File exists For some reason, fdb entries are only removed when libvirt explicitly stops CPUs, but nothing happens when we just get STOP event from QEMU. An alternative approach would be to make sure we always remove the entries regardless on why a domain was paused (e.g., during migration), but that would be a significantly more disruptive change with possible side effects.

[PATCH] qemucapabilitiesdata: Update x86_64 capabilities for qemu-6.0 release
by Peter Krempa 30 Apr '21

30 Apr '21

Update to the final state now that qemu 6.0 was released. Notable changes are the addition of 'EPYC-Rome-v2' cpu type and removal of 'query-netdev' which we didn't use. The rest is the usual churn caused by random registration of objects at compile time.

[PATCH] vm : forbid to start a removing vm
by Hogan Wang 29 Apr '21

29 Apr '21

From: Zhuang Shengen <zhuangshengen(a)huawei.com> When a vm is doing migration phase confirm, and then start it concurrently, it will lead to the vm out of libvirtd control. Cause Analysis: 1. thread1 migrate vm out. 2. thread2 start the migrating vm. 3. thread1 remove vm from domain list after migrate success. 4. thread2 acquired the vm job success and start the vm. 5. cannot find the vm any more by 'virsh list' command. Actually, the started vm is not exist in the domain list. Solution: Check the vm->removing state before start.
