[libvirt PATCH] qemu: fixing auto-detecting binary in domain capabilities
by Daniel P. Berrangé 17 Jan '20

17 Jan '20

The virConnectGetDomainCapabilities API accepts either a binary path to the emulator, or desired guest arch. If guest arch is not given, then the host arch is assumed. In the case where the binary is not given, the code tried to find the emulator binary in the existing list of cached emulator capabilities. This is not valid since we switched to lazy population of the cache in: commit 3dd91af01f30c5bda6328454ef49f3afece755d6 Author: Daniel P. Berrangé <berrange(a)redhat.com> Date: Mon Dec 2 13:04:26 2019 +0000 qemu: stop creating capabilities at driver startup As a result of this change, if there are no persistent guests defined using the requested guest architecture, virConnectGetDomainCapabilities will fail to find an emulator binary. The solution is to stop relying on the cached capabilities to find the binary and instead use the same logic we use to pick default a binary per arch when populating capabilities.

[libvirt PATCH] src: conditionalize / remove use of sys/ioctl.h
by Daniel P. Berrangé 17 Jan '20

17 Jan '20

Remove many imports of sys/ioctl.h which are redundant, and conditionalize remaining usage that needs to compile on Windows platforms. The previous change to remove the "nonblocking" gnulib module indirectly caused the loss of the "ioctl" gnulib module that we did not explicitly list in bootstrap.conf despite relying on. Rather than re-introduce the "ioctl" module this patch makes it redundant. Signed-off-by: Daniel P.

[libvirt PATCH v2 00/13] even less gnulib: 25 more modules purged, leaving 25 to go
by Daniel P. Berrangé 17 Jan '20

17 Jan '20

A continued effort to purge gnulib from the libvirt build system. The bulk of the win comes from implementing our own Winsock portability wrappers. The use of GSocket turned out to have many complications, making it hard for us to achieve the same level of functionality as we currently have. Thus we take a simpler wrapping approach that GNULIB does for Winsock too. Changed in v2: - Don't import intprops.h, use replacement macros instead - Various fixes to windows socket portability patch and actually verify virsh works - Simplify some ifdef checks to use WIN32 instead of a more complex conditional Daniel P. Berrangé (13): src: replace use of INT_BUFSIZE_BOUND macros src: remove use of the INT_MULTIPLY_OVERFLOW macro tests: always declare environ build: validate headers against local gnulib not git repo util: add detection of openpty function util: introduce compat wrappers for Winsock2 src: convert code to use new socket portability wrappers util: pull gnulib physmem impl into local code util: replace atomic ops impls with g_atomic_int* src: replace verify(expr) with G_STATIC_ASSERT(expr) src: conditionally exclude cfmakeraw/termios.h on WIN32 src: replace gmtime_r/localtime_r/strftime with GDateTime bootstrap: remove 25 more gnulib modules bootstrap.conf | 50 --- build-aux/syntax-check.mk | 29 +- configure.ac | 5 +- examples/c/misc/event-test.c | 12 +- m4/virt-manywarnings.m4 | 339 ++++++++++++++++++++ m4/virt-warnings.m4 | 115 +++++++ src/conf/capabilities.c | 1 - src/conf/domain_conf.c | 11 +- src/conf/snapshot_conf.h | 2 +- src/conf/virdomaincheckpointobjlist.c | 8 +- src/esx/esx_network_driver.c | 2 +- src/esx/esx_storage_backend_iscsi.c | 2 +- src/esx/esx_storage_backend_vmfs.c | 2 +- src/hyperv/hyperv_driver.c | 3 +- src/internal.h | 3 +- src/libvirt-domain.c | 6 +- src/libxl/libxl_domain.c | 12 +- src/libxl/libxl_driver.c | 2 +- src/libxl/xen_xm.c | 3 +- src/lxc/lxc_process.c | 4 +- src/nwfilter/nwfilter_dhcpsnoop.c | 10 +- src/nwfilter/nwfilter_ebiptables_driver.c | 35 +- src/nwfilter/nwfilter_learnipaddr.c | 14 +- src/qemu/qemu_blockjob.h | 4 +- src/qemu/qemu_capabilities.c | 2 +- src/qemu/qemu_command.c | 17 +- src/qemu/qemu_driver.c | 12 +- src/qemu/qemu_firmware.h | 2 +- src/qemu/qemu_migration_params.c | 2 +- src/qemu/qemu_process.c | 4 +- src/remote/remote_daemon_dispatch.c | 15 +- src/remote/remote_driver.c | 5 +- src/rpc/virnetsocket.c | 34 +- src/util/Makefile.inc.am | 3 + src/util/virarch.c | 3 +- src/util/viratomic.h | 351 +------------------- src/util/vircgroup.h | 2 +- src/util/vircrypto.c | 2 +- src/util/virenum.h | 8 +- src/util/virfdstream.c | 10 +- src/util/virfile.c | 25 +- src/util/virhostcpu.c | 4 +- src/util/virhostmem.c | 182 +++++++++-- src/util/virinitctl.c | 4 +- src/util/virkeycode.c | 22 +- src/util/virlog.c | 3 +- src/util/virmacaddr.h | 2 +- src/util/virnetdevbridge.c | 10 +- src/util/virobject.h | 8 +- src/util/virperf.c | 2 +- src/util/virpidfile.c | 7 +- src/util/virportallocator.c | 8 +- src/util/virprocess.c | 2 +- src/util/virsocket.c | 369 ++++++++++++++++++++++ src/util/virsocket.h | 92 ++++++ src/util/virstoragefile.c | 4 +- src/util/virstring.h | 2 + src/util/virtime.c | 35 +- src/util/virtypedparam.h | 2 +- src/util/virutil.c | 33 +- src/vz/vz_driver.c | 2 +- tests/commandhelper.c | 3 + tests/commandtest.c | 3 + tests/qemuxml2argvmock.c | 12 +- tests/viratomictest.c | 2 +- tests/virstringtest.c | 7 +- tests/virsystemdtest.c | 5 +- tests/virtimetest.c | 39 ++- tools/virsh-checkpoint.c | 20 +- tools/virsh-domain-monitor.c | 17 +- tools/virsh-domain.c | 15 +- tools/virsh-network.c | 13 +- tools/virsh-nodedev.c | 2 +- tools/virsh-pool.c | 2 +- tools/virsh-secret.c | 2 +- tools/virsh-snapshot.c | 19 +- tools/virsh.h | 1 - tools/virt-admin.c | 55 +--- tools/virt-host-validate-common.c | 4 +- tools/virt-login-shell.c | 7 +- tools/vsh.c | 31 +- tools/vsh.h | 4 +- 82 files changed, 1400 insertions(+), 827 deletions(-) create mode 100644 m4/virt-manywarnings.m4 create mode 100644 m4/virt-warnings.m4 create mode 100644 src/util/virsocket.c create mode 100644 src/util/virsocket.h -- 2.24.1

[libvirt] [PATCH v2 0/8] Don't hold both monitor and agent jobs at the same time
by Jonathon Jongsma 16 Jan '20

16 Jan '20

We have to assume that the guest agent may be malicious, so we don't want to allow any agent queries to block any other libvirt API. By holding a monitor job and an agent job while we're querying the agent, any other threads will be blocked from using the monitor while the agent is unresponsive. Because libvirt waits forever for an agent response, this makes us vulnerable to a denial of service from a malicious (or simply buggy) guest agent. Most of the patches in the first series were already reviewed and pushed, but a couple remain: the filesystem info functions. The problem with these functions is that the agent functions access the vm definition (owned by the domain). If a monitor job is not held while this is done, the vm definition could change while we are looking up the disk alias, leading to a potentional crash. This series tries to fix this by moving the disk alias searching up a level from qemu_agent.c to qemu_driver.c. The code in qemu_agent.c will only return the raw data returned from the agent command response. After the agent response is returned and the agent job is ended, we can then look up the disk alias from the vm definition while the domain object is locked. In addition, a few nearby cleanups are included in this series, notably changing to glib allocation API in a couple of places. Jonathon Jongsma (8): qemu: rename qemuAgentGetFSInfoInternalDisk() qemu: store complete agent filesystem information qemu: Don't store disk alias in qemuAgentDiskInfo qemu: don't access vmdef within qemu_agent.c qemu: remove qemuDomainObjBegin/EndJobWithAgent() qemu: use glib alloc in qemuAgentGetFSInfoFillDisks() qemu: use glib allocation apis for qemuAgentFSInfo Use glib alloc API for virDomainFSInfo src/libvirt-domain.c | 12 +- src/qemu/THREADS.txt | 58 +----- src/qemu/qemu_agent.c | 268 ++++------------------------ src/qemu/qemu_agent.h | 33 +++- src/qemu/qemu_domain.c | 56 +----- src/qemu/qemu_domain.h | 7 - src/qemu/qemu_driver.c | 246 +++++++++++++++++++++++-- src/remote/remote_daemon_dispatch.c | 2 +- tests/qemuagenttest.c | 196 ++++---------------- 9 files changed, 336 insertions(+), 542 deletions(-) -- 2.21.0

[PATCH] qemu: Don't emit SUSPENDED_POSTCOPY event on destination
by Jiri Denemark 16 Jan '20

16 Jan '20

When pause-before-switchover QEMU capability is enabled, we get STOP event before MIGRATION event with postcopy-active state. To properly handle post-copy migration and emit correct events commit v4.10.0-rc1-4-geca9d21e6c added a hack to qemuProcessHandleMigrationStatus which translates the paused state reason to VIR_DOMAIN_PAUSED_POSTCOPY and emits VIR_DOMAIN_EVENT_SUSPENDED_POSTCOPY event when migration state changes to post-copy. However, the code was effective on both sides of migration resulting in a confusing VIR_DOMAIN_EVENT_SUSPENDED_POSTCOPY event on the destination host, where entering post-copy mode is already properly advertised by VIR_DOMAIN_EVENT_RESUMED_POSTCOPY event. https://bugzilla.redhat.com/show_bug.cgi?id=1791458 Signed-off-by: Jiri Denemark <jdenemar(a)redhat.com> --- src/qemu/qemu_process.c | 1 + 1 file changed, 1 insertion(+) diff --git a/src/qemu/qemu_process.c b/src/qemu/qemu_process.c index 4195042194..a7bbab9e56 100644 --- a/src/qemu/qemu_process.c +++ b/src/qemu/qemu_process.c @@ -1653,6 +1653,7 @@ qemuProcessHandleMigrationStatus(qemuMonitorPtr mon G_GNUC_UNUSED, virDomainObjBroadcast(vm); if (status == QEMU_MONITOR_MIGRATION_STATUS_POSTCOPY && + priv->job.asyncJob == QEMU_ASYNC_JOB_MIGRATION_OUT && virDomainObjGetState(vm, &reason) == VIR_DOMAIN_PAUSED && reason == VIR_DOMAIN_PAUSED_MIGRATION) { VIR_DEBUG("Correcting paused state reason for domain %s to %s", -- 2.25.0

[libvirt] [PATCH] util: storagefile: Properly set transport type when parsing NBD strings
by Peter Krempa 16 Jan '20

16 Jan '20

When parsing legacy NBD backing file strings such as 'nbd:unix:/tmp/sock:exportname=/' we'd fail to set the transport to VIR_STORAGE_NET_HOST_TRANS_UNIX. This started to be a problem once we actually started to generate config of the backing store on the command line with -blockdev as the JSON code would try to format it as TCP and fail with: internal error: argument key 'host' must not have null value Set the type properly and add a test.

[libvirt] [PATCH v2 00/12] include result of bootstrap in git

16 Jan '20

This patch series is motivated by the effort to adopt Meson as our build system but all of it improves the current build system on its own. It moves the burden to run bootstrap/autoreconf to developers which means it will save some time for others when there is any change to the build system. Since one of the patches is slightly bigger here is link to git: <https://gitlab.com/phrdina/libvirt.git> branch <configure> Changes in v2: - some patches removed Pavel Hrdina (12): secret: move virSecretGetSecretString into virsecret configure.ac: add check for getegid function bootstrap.conf: drop gnulib tests from libvirt bootstrap.conf: always copy files bootstrap.conf: declare bootstrap

[libvirt] FYI: intention to remove mail subject prefix & footer text
by Daniel P. Berrangé 15 Jan '20

15 Jan '20

Hi List Subscribers, In recent months we have been seeing an increasing number of bounced deliveries from libvirt mailing lists[1] due to DMARC policies on list subscriber's mail servers. IOW, many subscribers are only receiving a subset of mails sent to the libvirt mailing lists. We believe the root cause of many of the problems is that mailman is modifying the mail subject to add the "[libvirt]" / "[libvirt-users]" prefix, and modifying the mail body to add the footer with links to the listinfo page. These modifications invalidate the DKIM signatures on mails sent to the list by some of our subscribers. This in turn causes DMARC policy rejections by the destination SMTP servers when mailman delivers messages. The solution is to disable any feature in mailman which modifies parts of the mail validated by the DKIM signature. This means removing the subject prefix and the mail body header. Further information on this approach can be seen here: https://begriffs.com/posts/2018-09-18-dmarc-mailing-list.html QEMU has made the same change on their mailing list last year: https://lists.gnu.org/archive/html/qemu-devel/2019-09/msg00416.html If you are currently doing mail filtering / sorting based on the subject prefix, you will need to change to use the List-Id header instead. I will wait until the latter part of next week before making this change to allow people time to adapt any filters. Regards, Daniel [1] technically moderators have only been seeing bounces for messages on libvirt-users-list, but that's because we've got mailman configured to send libvir-list bounces to /dev/null. -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :|

[libvirt] [PATCH 0/2] fix segfaults on qemuhotplugtest
by Christian Ehrhardt 15 Jan '20

After debugging for a while and eventually finding the root cause we discussed this on IRC today: <cpaelzer> danpb: BTW the test crash in 6.0 that I'm tracing (asked yesterday) is virHostdevManagerInitialize failing <cpaelzer> the test goes on with mgr set to 0x0 and that is the segfault later on <cpaelzer> virSetError was helpful as "Could not initialize HostdevManager operation failed: Failed to create state dir '/sbuild-nonexistent/.cache/libvirt/hostdevmgr'" sounds like a very testbed-specific issue that I might be able to solve when invoking the tests <danpb> hmm, seems like we're missing a mock for mkdir() <danpb> i guess we should mock virFileMakePath in this case This series got v6.0.0 building in Ubuntu, so I thought it is worth to submit it for review.

[libvirt] Release of libvirt-6.0.0
by Daniel Veillard 15 Jan '20

15 Jan '20

As planned the release is available, tagged in git, and the signed tarball and source rpm are available from the usual place: https://libvirt.org/sources/ I also made the release of the pythn bindings which can be found at: https://libvirt.org/sources/python/ This release carries some serious changes, dropping the support for python2 and the phyp Power Hypervisor. This comes with a set of new features and improvements too: Packaging changes: - support for python2 is removed Libvirt is no longer able to be built using the Python 2 binary. Python 3 must be used instead. - docs: the python docutils toolset is now required The use of rst2html has been introduced for the website build process since docs are now being written in the RST as an alternative to HTML. New features: - new PCI hostdev address type: unassigned A new PCI hostdev address type 'unassigned' is introduced. An unassigned PCI hostdev behaves like any regular PCI hostdev inside Libvirt, but it is not usable by the guest. This gives the user a new option to manage the binding of PCI devices via Libvirt, declaring PCI hostdevs in the domain XML but allowing just a subset of them to be assigned to the guest. - Provide init scripts for sub-deaemons So far libvirt shipped systemd unit files for sub-daemons. With this release, init scripts are available too. Package maintainers can choose which one to install via --with-init-script configure option. - qemu: Support cold-unplug of sound devices - qemu: Implement VIR_MIGRATE_PARAM_TLS_DESTINATION This flag, which can be enabled using virsh's --tls-destination option, allows migration to succeed in situations where there is a mismatch between the destination's hostname and the information stored in its TLS certificate. - qemu: Support reporting memory bandwidth usage stats Implement Intel RDT-MBM in libvirt. The stats can be obtained via virsh domstats --memory. - qemu: Allow accessing NVMe disks directly Before this release there were two ways to configure a NVMe disk for a domain. The first was using <disk/> with the <source/> pointing to the /dev/nvmeXXXX. The other was using PCI assignment via <hostdev/> element. Both have their disadvantages: the former adds latency of file system and block layers of the host kernel, the latter prohibits domain migration. In this release the third way of configuring NVMe disk is added which combines the advantages and drops disadvantages of the previous two ways. It's accessible via <disk type='nvme'/>. Removed features: - 'phyp' Power Hypervisor driver removed The 'phyp' Power Hypervisor driver has not seen active development since 2011 and does not seem to have any real world usage. It has now been removed. Improvements: - qemu: xz save image compression is faster When using the xz format to compressed virtual machine saved state images, the "-3" compression level preset is now used. This results in slightly larger files, but with a massively reduced time to compress. The xz format offers the best compression level for saved state images, albeit still with the slowest running time. For the fastest possible running time, at cost of the larest compressed size, lzop should be used. - domain: Improve job stat handling It is now possible to retrieve stats for completed and failed jobs. - qemu: Don't hold monitor and agent job at the same time Before this change, a malicious (or buggy) qemu-guest-agent running in the guest could make other libvirt APIs unavailable for an unbounded amount of time. Bug fixes: - qemu: Report error if backing image format is not specified explicitly For a long time libvirt was assuming that a backing file is RAW when the format was not specified. This didn't pose a problem until blockdev support was enabled in last release. Libvirt now requires that the format is specified in the image metadata or domain XML and the VM will refuse to start otherwise. Additionally the error message now links to the knowledge base which summarizes how to fix the images. - qemu: Fix non-shared storage migration over NBD - qemu: Generate a single MAC address for hotplugged network devices Since libvirt 4.6.0, when hotplugging a network device that didn't have a MAC address already assigned by the user, two separate addresses would be generated: one for the live configuration, which would show up immediately, and one for the inactive configuration, which would show up after the first reboot. This situation was clearly undesirable, so a single MAC address is now generated and used both for the live configuration and the inactive one. thanks everybody who helped on this release, with reports, fixes, reviews, ideas, documentation, etc ... Enjoy the release, next one will be scheduled at the end of February !

[libvirt] [PATCH v2 86/86] numa: remove deprecated implicit RAM distribution between nodes
by Igor Mammedov 15 Jan '20

15 Jan '20

Feature has been deprecated since 4.1 (4bb4a273), remove it. As result if RAM distribution wasn't specified explicitly, the machine won't start and CLI should be changed to explicitly assign RAM to nodes using options: -node node,memdev (5.0 and newer machine types) -node node,mem (4.2 and older machine types) It's recommended to use "memdev" variant for new virtual machines and use "mem" only when it's necessary to migrate already existing virtual machine started with implicit RAM distribution.

[libvirt] Getting memory usage info for domains with balloon driver disabled
by Tomasz Barański 15 Jan '20

15 Jan '20

Hello, I'm looking for a way to read guest memory usage information (RAM used, RAM available) for VMs with balloon driver disabled. oVirt used to read that information using ovirt guest agent, but OGA is no longer used (and not even available for RHEL8). I've seen that there was a discussion about adding it to the QEMU guest agent a couple years back[1] but it has not been implemented. dominfo doesn't help: # virsh dominfo 306c001c-f569-4afa-b024-81135c566a73 | grep memory Max memory: 1048576 KiB Used memory: 1048576 KiB dommemstat doesn't help: # virsh dommemstat 306c001c-f569-4afa-b024-81135c566a73 rss 1049432 Neither does domstats. Is there any other way to get the info? [1] https://bugzilla.redhat.com/show_bug.cgi?id=1101915 Tomo

[libvirt] [PATCH 00/12] even less gnulib: 25 more modules purged, leaving 25 to go
by Daniel P. Berrangé 15 Jan '20

15 Jan '20

A continued effort to purge gnulib from the libvirt build system. The bulk of the win comes from implementing our own Winsock portability wrappers. The use of GSocket turned out to have many complications, making it hard for us to achieve the same level of functionality as we currently have. Thus we take a simpler wrapping approach that GNULIB does for Winsock too. NB this has only been compile tested so far. The sockets stuff definitely needs functional testing on Windows before I dare push it Daniel P. Berrangé (12): src: import gnulib's intprops.h header tests: always declare environ build: validate headers against local gnulib not git repo util: add detection of openpty function util: introduce compat wrappers for Winsock2 src: convert code to use new socket portability wrappers util: pull gnulib physmem impl into local code util: replace atomic ops impls with g_atomic_int* src: replace verify(expr) with G_STATIC_ASSERT(expr) src: add check for termios.h and conditionally include it src: replace gmtime_r/localtime_r/strftime with GDateTime bootstrap: remove 25 more gnulib modules bootstrap.conf | 50 -- build-aux/syntax-check.mk | 18 +- configure.ac | 5 + m4/virt-manywarnings.m4 | 339 ++++++++++++++ m4/virt-warnings.m4 | 115 +++++ src/conf/capabilities.c | 1 - src/conf/domain_conf.c | 11 +- src/conf/snapshot_conf.h | 2 +- src/conf/virdomaincheckpointobjlist.c | 8 +- src/esx/esx_network_driver.c | 2 +- src/esx/esx_storage_backend_iscsi.c | 2 +- src/esx/esx_storage_backend_vmfs.c | 2 +- src/hyperv/hyperv_driver.c | 2 +- src/internal.h | 1 - src/libvirt-domain.c | 2 +- src/libxl/libxl_domain.c | 12 +- src/libxl/libxl_driver.c | 2 +- src/libxl/xen_xm.c | 3 +- src/lxc/lxc_process.c | 4 +- src/nwfilter/nwfilter_dhcpsnoop.c | 10 +- src/nwfilter/nwfilter_ebiptables_driver.c | 2 +- src/nwfilter/nwfilter_learnipaddr.c | 2 +- src/qemu/qemu_blockjob.h | 4 +- src/qemu/qemu_capabilities.c | 2 +- src/qemu/qemu_command.c | 17 +- src/qemu/qemu_driver.c | 12 +- src/qemu/qemu_firmware.h | 2 +- src/qemu/qemu_migration_params.c | 2 +- src/qemu/qemu_process.c | 4 +- src/remote/remote_daemon_dispatch.c | 12 +- src/remote/remote_driver.c | 2 +- src/rpc/virnetsocket.c | 34 +- src/util/Makefile.inc.am | 4 + src/util/virarch.c | 3 +- src/util/viratomic.h | 351 +-------------- src/util/vircgroup.h | 2 +- src/util/vircrypto.c | 2 +- src/util/virenum.h | 8 +- src/util/virfdstream.c | 4 +- src/util/virfile.c | 18 +- src/util/virhostcpu.c | 3 +- src/util/virhostmem.c | 182 ++++++-- src/util/virinitctl.c | 4 +- src/util/virintprops.h | 526 ++++++++++++++++++++++ src/util/virkeycode.c | 22 +- src/util/virlog.c | 2 +- src/util/virmacaddr.h | 2 +- src/util/virnetdevbridge.c | 2 +- src/util/virobject.h | 8 +- src/util/virperf.c | 2 +- src/util/virpidfile.c | 2 +- src/util/virportallocator.c | 8 +- src/util/virprocess.c | 2 +- src/util/virsocket.c | 346 ++++++++++++++ src/util/virsocket.h | 89 ++++ src/util/virstoragefile.c | 4 +- src/util/virtime.c | 35 +- src/util/virtypedparam.h | 2 +- src/util/virutil.c | 4 +- src/vz/vz_driver.c | 2 +- tests/commandhelper.c | 3 + tests/commandtest.c | 3 + tests/qemuxml2argvmock.c | 12 +- tests/viratomictest.c | 2 +- tests/virstringtest.c | 7 +- tests/virsystemdtest.c | 2 +- tests/virtimetest.c | 39 +- tools/virsh-checkpoint.c | 20 +- tools/virsh-domain-monitor.c | 16 +- tools/virsh-domain.c | 15 +- tools/virsh-network.c | 13 +- tools/virsh-nodedev.c | 2 +- tools/virsh-pool.c | 2 +- tools/virsh-secret.c | 2 +- tools/virsh-snapshot.c | 19 +- tools/virsh.h | 1 - tools/virt-admin.c | 55 +-- tools/virt-host-validate-common.c | 4 +- tools/virt-login-shell.c | 7 +- tools/vsh.c | 16 +- tools/vsh.h | 4 +- 81 files changed, 1836 insertions(+), 733 deletions(-) create mode 100644 m4/virt-manywarnings.m4 create mode 100644 m4/virt-warnings.m4 create mode 100644 src/util/virintprops.h create mode 100644 src/util/virsocket.c create mode 100644 src/util/virsocket.h -- 2.24.1
