[libvirt] [RFC PATCH] docs: Use our own implementation for fetching the RSS data
by Martin Kletzander 19 Jun '19

19 Jun '19

This is just a small script I wrote. It works the same way as all the libraries together which we are bundling, but with just JS. The only difference is that the day of the date is formatted as 2-digit, but this should be a bug in Firefox (at least locally for me) as the documentation states that type 'numeric' should actually not have leading zeros. It will not be executed when the page is loaded locally. It also uses the same proxy that query-rss uses. We can get rid of that, but we'd either need to have our own proxy, send a sss header to allow fetching the atom.xml or providing JSONP access to the RSS feed on virt-planet.

[libvirt] [PATCH] remote: drop code for migrating config files from pre-XDG dir layout
by Daniel P. Berrangé 19 Jun '19

19 Jun '19

The unprivileged libvirtd daemon switched to use the XDG dir layout in the 0.9.13 release, and included code for moving config files from the old location. The chances of someone upgrading libvirt from <= 0.9.12 directly to libvirt >= 5.5.0 is close enough to zero that we can reasonably drop the back compat code. Signed-off-by: Daniel P.

[libvirt] [PATCH] test_driver: implement virDomainSendProcessSignal

Only succeed when @pid_value is 1, since according to the docs this is the minimum requirement for any driver to implement this API. >From man 2 kill: The only signals that can be sent to process ID 1, the init process, are those for which init has explicitly installed signal handlers. Regarding sending SIGTERM and SIGKILL to init, the test driver domains pretend to run Linux, and on Linux init/systemd explicitly ignores these signals. Correspondingly, we can assume that no signal handlers are installed for any other signal and succeed by doing nothing.

[libvirt] [PATCH] apparmor: Add openGraphicsFD rule for named profile
by Christian Ehrhardt 19 Jun '19

19 Jun '19

Commit a3ab6d42 changed the libvirtd profile to a named profile but neglected to accommodate the change in the qemu profile ptrace and signal rules. Later on 4ec3cf9a fixed that for ptrace and signal but openGraphicsFD is still missing. As a result, libvirtd is unable to open UI on libvirt >=5.1 e.g. with virt-manager. Add openGraphicsFD rule that references the libvirtd profile by name in addition to full binary path.

[libvirt] [PATCH] remote: use VIR_DRV_OPEN_REMOTE_USER in ssh transport checks
by Daniel P. Berrangé 19 Jun '19

19 Jun '19

We currently refuse to connect to remote libvirtd over SSH if we see the path ends in /session. Earlier on though we checked for /session and set the VIR_DRV_OPEN_REMOTE_USER flag. There is one subtle distinction though with the test driver. All test URIs are marked with this flag, regardless of whether the URI indicates a local or remote connection. Previously a local connection to the test driver would have used the unprivileged libvirtd while a remote connection would have tried the privileged libvirtd. With this we are consistent and use the unprivileged for both local & remote, if the current user is non-root. Signed-off-by: Daniel P.

[libvirt] [PATCH] remote: remove obsolete & incorrect comment from libvirtd.conf
by Daniel P. Berrangé 19 Jun '19

19 Jun '19

The libvirtd.conf file has a comment pointing people to format.html which has nothing todo with the configuration file format. It also has a comment about tests/daemon-conf which no longer exists, and even if it did exist such comment is not relevant to end users when this file is installed in /etc/. Signed-off-by: Daniel P.

[libvirt] [PATCH 0/3] qemu: Introduce 'features' QMP query (blockdev-add saga)
by Peter Krempa 19 Jun '19

19 Jun '19

qemu introduced a new field in the QMP schema which allows to query features for a schema entry. Add the support to libvirt for querying it. Patch 3/3 is part of my blockdev series and I don't mind holding on to it until I post patches which make use of it. It's posted here mostly for demonstration purpose.

[libvirt] [PATCH v6 00/23] network: refactor to decouple virt drivers from network driver
by Daniel P. Berrangé 18 Jun '19

18 Jun '19

An update to v1: https://www.redhat.com/archives/libvir-list/2018-December/msg00681.html v2: https://www.redhat.com/archives/libvir-list/2019-February/msg01581.html v3: https://www.redhat.com/archives/libvir-list/2019-March/msg01259.html v4: https://www.redhat.com/archives/libvir-list/2019-April/msg01186.html v5: https://www.redhat.com/archives/libvir-list/2019-May/msg00358.html Currently the network driver registers a set of callbacks with the virt driver in order to handle allocating/releasing network ports associated with guest NICs. This series introduces a virNetworkPortPtr object and associated XML that describes a network port. The virt drivers now call public APIs associated with this new object to create/delete ports for guest NICs. Changed in v6: - Fixed mistakes in RNG schema & example XML - Fix docs typos Changed in v5: - Separately track ports with type=network vs type=bridge to deal with fallout after reverting patches which merged them - Add RNG schema and XML format docs - Change to use classID attr on <bandwidth> isntead of of separate <class id="xx"/> element - Drop obsolete driver deps from RPM spec - Other misc bug fixes found during testing Changed in v4: - Merged the ACKd patches which didn't depend on other un-acked parts - Improve bandwidth error messages - Ensure we set floor sum to zero when starting network - Misc fixes for previous review comments NB, I have not added missing docs for the new XML doc format yet. This is work in progress. Changed in v3: - Remove unused API symbol - Fix dist of test data files Changed in v2: - Fix many bugs related to upgrades with running VMs - Convert over bandwidth controls to the new APIs - Handle reconnecting VIFs to bridges during startup - Much much more that I can't remember Daniel P.

[libvirt] [PATCH RFC 0/1] mdevctl: further config for vfio-ap
by Cornelia Huck 18 Jun '19

18 Jun '19

This patch adds a very rough implementation of additional config data for mdev devices. The idea is to make it possible to specify some type-specific key=value pairs in the config file for an mdev device. If a device is started automatically, the device is stopped and restarted after applying the config. The code has still some problems, like not doing a lot of error handling and being ugly in general; but most importantly, I can't really test it, as I don't have the needed hardware. Feedback welcome; would be good to know if the direction is sensible in general. Also available at https://github.com/cohuck/mdevctl conf-data Cornelia Huck (1): allow to specify additional config data mdevctl.libexec | 25 ++++++++++++++++++++++ mdevctl.sbin | 56 ++++++++++++++++++++++++++++++++++++++++++++++++- 2 files changed, 80 insertions(+), 1 deletion(-) -- 2.20.1

[libvirt] [PATCH 0/4] docs: Use CDNJS, update JavaScript libraries
by Andrea Bolognani 18 Jun '19

18 Jun '19

We're carrying around embedded copies of a few JavaScript libraries for use in our homepage, and we've been unforgivably bad at keeping them up to date. Instead of serving JavaScript from libvirt.org, use CDNJS so that users will get better performance and the load on our Web server will decrease (win-win!); at the same time, move from the positively ancient versions we're currently using to the freshest ones available.

[libvirt] [PATCH v3] Produce more verbose error if cppi not found
by Michal Privoznik 18 Jun '19

18 Jun '19

It's fairly easy (especially for new contributors) to not spot the 'cppi not installed' line in the syntax-check output. Turn it into a banner that is more visible and at the same time add it as a build dependency. Unfortunately, RHEL doesn't ship cppi so we can add the dependency only for Fedora. Since it's v1 this has effectively became code copied over from Andrea's review suggestions.

[libvirt] [PATCH v2] Produce more verbose error if cppi not found
by Michal Privoznik 17 Jun '19

17 Jun '19

It's fairly easy (especially for new contributors) to not spot the 'cppi not installed' line in the syntax-check output. Turn it into a banner that is more visible and at the same time add it as a build dependency. Unfortunately, RHEL doesn't ship cppi so we can add the dependency only for Fedora.

[libvirt] [PATCH v4 0/3] numa: deprecate '-numa node, mem' and default memory distribution
by Igor Mammedov 17 Jun '19

17 Jun '19

Changes since v3: - simplify series by dropping idea of showing property values in "qom-list-properties" and use MachineInfo in QAPI schema instead Changes since v2: - taking in account previous review, implement a way for mgmt to intospect if '-numa node,mem' is supported by machine type as suggested by Daniel at https://www.mail-archive.com/qemu-devel@nongnu.org/msg601220.html * ammend "qom-list-properties" to show property values * add "numa-mem-supported" machine property to reflect if '-numa node,mem=SZ' is supported. It culd be used with '-machine none' or at runtime with --preconfig before numa memory mapping are configured * minor fixes to deprecation documentation mentioning "numa-mem-supported" property 1) "I'm considering to deprecating -mem-path/prealloc CLI options and replacing them with a single memdev Machine property to allow interested users to pick used backend for initial RAM (fixes mixed -mem-path+hostmem backends issues) and as a transition step to modeling initial RAM as a Device instead of (ab)using MemoryRegion APIs." (for more details see: https://www.mail-archive.com/qemu-devel@nongnu.org/msg596314.html) However there is a couple of roadblocks on the way (s390x and numa memory handling). I think I finally thought out a way to hack s390x in migration compatible manner, but I don't see any way to do it for -numa node,mem and default RAM assignement to nodes. Considering both numa usecases aren't meaningfully using NUMA (aside guest side testing) and could be replaced with explicitly used memdev parameter, I'd like to propose removing these fake NUMA friends on new machine types, hence this deprecation. And once the last machie type that supported the option is removed we would be able to remove option altogether. As result of removing deprecated options and replacing initial RAM allocation with 'memdev's (1), QEMU will allocate guest RAM in consistent way, fixing mixed use-case and allowing boards to move towards modelling initial RAM as Device(s). Which in its own turn should allow to cleanup NUMA/HMP/memory accounting code more by dropping ad-hoc node_mem tracking and reusing memory device enumeration instead.

[libvirt] [PATCH] build: Require cppi for syntax-check
by Michal Privoznik 17 Jun '19

17 Jun '19

Since its introduction in v0.8.0~314 we allowed for cppi to be not present for 'syntax-check' because the package did exist in Fedora Core 12. Well, we don't care anymore ¯\_(ツ)_/¯ All recent distros have it. Moreover, it's fairly easy to miss 'cppi not installed' message in sea of syntax-check output (esp. for newbies who probably benefit from it the most).

[libvirt] [PATCH 00/19] Use '#pragma once' in headers
by Jonathon Jongsma 14 Jun '19

14 Jun '19

Hi all, I'm trying to get up to speed with libvirt code, so I decided to start out with a slightly "mindless" task. I grabbed the '#pragma once' task from https://wiki.libvirt.org/page/BiteSizedTasks. This series covers the first part of the conversion. I chatted with Daniel Berrange briefly on IRC before starting, and he suggested that I should try to keep patches under 100k, and maybe each driver's source files as a single patch. I had a bit of difficulty deciding where to split the src/conf/ and src/util/ directories. So some of the files with more changes ended up being single-file patches. I tried to combine some related source files into patches, but at a certain point I ran out of obvious files to combine, so I combined a bunch of smaller miscellaneous files into one larger patch. It may not be ideal, but it's the best I could come up with. Alternative suggestions welcome. I'll follow up with the remaining changes if this division looks acceptable. Jonathon Jongsma (19): Use #pragma once in driver headers src/access: use #pragma once in headers src/admin: use #pragma once in headers src/bhyve: use #pragma once in headers conf: domain: use #pragma once in headers conf: network: use #pragma once in headers conf: nwfilter: use #pragma once in headers conf: node device: use #pragma once in headers conf: storage: use #pragma once in headers conf: misc: use #pragma once in headers src/cpu: use #pragma once in headers src/datatypes.h: use #pragma once src/esx: use #pragma once in headers src/hyperv: use #pragma once in headers src/interface: use #pragma once in headers src/internal.h: use #pragma once src/libvirt_internal.h: use #pragma once src/libxl: use #pragma once in headers src/logging: use #pragma once in headers src/access/viraccessdriver.h | 10 +- src/access/viraccessdrivernop.h | 7 +- src/access/viraccessdriverpolkit.h | 7 +- src/access/viraccessdriverstack.h | 7 +- src/access/viraccessmanager.h | 26 +-- src/access/viraccessperm.h | 11 +- src/admin/admin_server.h | 9 +- src/admin/admin_server_dispatch.h | 11 +- src/bhyve/bhyve_capabilities.h | 11 +- src/bhyve/bhyve_command.h | 15 +- src/bhyve/bhyve_conf.h | 7 +- src/bhyve/bhyve_device.h | 11 +- src/bhyve/bhyve_domain.h | 11 +- src/bhyve/bhyve_driver.h | 9 +- src/bhyve/bhyve_monitor.h | 11 +- src/bhyve/bhyve_parse_command.h | 5 +- src/bhyve/bhyve_process.h | 7 +- src/bhyve/bhyve_utils.h | 31 ++- src/conf/capabilities.h | 23 +-- src/conf/cpu_conf.h | 23 +-- src/conf/device_conf.h | 33 ++- src/conf/domain_addr.h | 16 +- src/conf/domain_audit.h | 10 +- src/conf/domain_capabilities.h | 15 +- src/conf/domain_conf.h | 91 ++++----- src/conf/domain_event.h | 11 +- src/conf/domain_nwfilter.h | 5 +- src/conf/interface_conf.h | 23 +-- src/conf/moment_conf.h | 11 +- src/conf/netdev_bandwidth_conf.h | 15 +- src/conf/netdev_vlan_conf.h | 13 +- src/conf/netdev_vport_profile_conf.h | 14 +- src/conf/network_conf.h | 52 +++-- src/conf/network_event.h | 11 +- src/conf/networkcommon_conf.h | 17 +- src/conf/node_device_conf.h | 31 ++- src/conf/node_device_event.h | 11 +- src/conf/node_device_util.h | 7 +- src/conf/numa_conf.h | 18 +- src/conf/nwfilter_conf.h | 93 ++++----- src/conf/nwfilter_ipaddrmap.h | 5 +- src/conf/nwfilter_params.h | 28 ++- src/conf/object_event.h | 11 +- src/conf/object_event_private.h | 7 +- src/conf/secret_conf.h | 15 +- src/conf/secret_event.h | 11 +- src/conf/snapshot_conf.h | 13 +- src/conf/storage_adapter_conf.h | 11 +- src/conf/storage_capabilities.h | 8 +- src/conf/storage_conf.h | 41 ++-- src/conf/storage_event.h | 11 +- src/conf/virchrdev.h | 9 +- src/conf/virconftypes.h | 5 +- src/conf/virdomainmomentobjlist.h | 17 +- src/conf/virdomainobjlist.h | 21 +- src/conf/virdomainsnapshotobjlist.h | 21 +- src/conf/virinterfaceobj.h | 7 +- src/conf/virnetworkobj.h | 9 +- src/conf/virnodedeviceobj.h | 13 +- src/conf/virnwfilterbindingdef.h | 13 +- src/conf/virnwfilterbindingobj.h | 11 +- src/conf/virnwfilterbindingobjlist.h | 8 +- src/conf/virnwfilterobj.h | 11 +- src/conf/virsavecookie.h | 13 +- src/conf/virsecretobj.h | 11 +- src/conf/virstorageobj.h | 11 +- src/cpu/cpu.h | 19 +- src/cpu/cpu_arm.h | 7 +- src/cpu/cpu_map.h | 7 +- src/cpu/cpu_ppc64.h | 7 +- src/cpu/cpu_ppc64_data.h | 8 +- src/cpu/cpu_s390.h | 7 +- src/cpu/cpu_x86.h | 9 +- src/cpu/cpu_x86_data.h | 58 +++--- src/datatypes.h | 89 ++++---- src/driver-hypervisor.h | 12 +- src/driver-interface.h | 12 +- src/driver-network.h | 12 +- src/driver-nodedev.h | 12 +- src/driver-nwfilter.h | 12 +- src/driver-secret.h | 12 +- src/driver-state.h | 12 +- src/driver-storage.h | 12 +- src/driver-stream.h | 12 +- src/driver.h | 37 ++-- src/esx/esx_driver.h | 5 +- src/esx/esx_interface_driver.h | 7 +- src/esx/esx_network_driver.h | 7 +- src/esx/esx_private.h | 15 +- src/esx/esx_storage_backend_iscsi.h | 7 +- src/esx/esx_storage_backend_vmfs.h | 7 +- src/esx/esx_storage_driver.h | 7 +- src/esx/esx_stream.h | 9 +- src/esx/esx_util.h | 13 +- src/esx/esx_vi.h | 37 ++-- src/esx/esx_vi_methods.h | 11 +- src/esx/esx_vi_types.h | 13 +- src/hyperv/hyperv_driver.h | 5 +- src/hyperv/hyperv_private.h | 13 +- src/hyperv/hyperv_util.h | 9 +- src/hyperv/hyperv_wmi.h | 21 +- src/hyperv/hyperv_wmi_classes.h | 27 ++- src/hyperv/openwsman.h | 35 ++-- src/interface/interface_driver.h | 5 +- src/internal.h | 295 +++++++++++++-------------- src/libvirt_internal.h | 7 +- src/libxl/libxl_capabilities.h | 29 ++- src/libxl/libxl_conf.h | 101 +++++---- src/libxl/libxl_domain.h | 29 ++- src/libxl/libxl_driver.h | 5 +- src/libxl/libxl_logger.h | 7 +- src/libxl/libxl_migration.h | 11 +- src/logging/log_daemon.h | 9 +- src/logging/log_daemon_config.h | 7 +- src/logging/log_daemon_dispatch.h | 7 +- src/logging/log_handler.h | 9 +- src/logging/log_manager.h | 9 +- 117 files changed, 928 insertions(+), 1296 deletions(-) -- 2.20.1

[libvirt] [PATCH v2] qemu: fix pr-helper0 remain
by Jie Wang 13 Jun '19

13 Jun '19

If libvirt receive DISCONNECTED event and set prDaemonRunning to false, and qemuDomainRemoveDiskDevice is performing in the meantime. qemuDomainRemoveDiskDevice will return directly by prDaemonRunning check, so the pr-helper0 object will remain. In that case we should try harder and also kill the pr-helper process, so qemuProcessKillManagedPRDaemon could use the same treatment.

[libvirt] [PATCH] qemu: Add support for overriding max threads per process limit
by Jim Fehlig 12 Jun '19

12 Jun '19

Some VM configurations may result in a large number of threads created by the associated qemu process which can exceed the system default limit. The maximum number of threads allowed per process is controlled by the pids cgroup controller and is set to 16k when creating VMs with systemd's machined service. The maximum number of threads per process is recorded in the pids.max file under the machine's pids controller cgroup hierarchy, e.g. $cgrp-mnt/pids/machine.slice/machine-qemu\\x2d1\\x2dtest.scope/pids.max Maximum threads per process is controlled with the TasksMax property of the systemd scope for the machine. This patch adds an option to qemu.conf which can be used to override the maximum number of threads allowed per qemu process. If the value of option is greater than zero, it will be set in the TasksMax property of the machine's scope after creating the machine.

[libvirt] [PATCH v2 0/4] test_driver: implement virDomainSaveImageGetXMLDesc and virDomainSaveImageDefineXML
by Ilias Stamatis 11 Jun '19

11 Jun '19

Changed in v2: * in testDomainSaveImageDefineXML check first that a saved image already exists before parsing the new file * reordered the arguments of testDomainSaveImageWrite in order for its signature to be consistent with testDomainSaveImageOpen While implementing virDomainSaveImageGetXMLDesc and virDomainSaveImageDefineXML for the test driver, I realized that there exists already code for saving and loading test images which can be reused. However, it needed to be extracted from testDomainSaveFlags and testDomainRestoreFlags into separate functions. The new functions are inspired by the corresponding QEMU driver code where e.g. qemuDomainSaveImageOpen serves as a helper used by other functions. This series of patches initially extracts the code mentioned above into separate functions and then provides the test driver with implementations for virDomainSaveImageGetXMLDesc and virDomainSaveImageDefineXML which make use of the newly introduced functions.

[libvirt] [jenkins-ci PATCH] lcitool: Don't warn when using package manager directly
by Andrea Bolognani 11 Jun '19

11 Jun '19

We only do this when performing operations that the corresponding Ansible module doesn't support, so we know what we're doing and don't want warnings to show up. Note that while only the dnf and yum modules complain at the moment, we might as well use warn=no everywhere so that we're already covered in case in the future the pkgng module starts detecting this as well.

What if you intend to hotplug more devices? > These properties allow you to ask bios to reserve extra space. Is it fair to say that setting io-reserve=0 for a pcie-root-port would be a way to implement the requirements set forth in https://bugzilla.redhat.com/show_bug.cgi?id=1408810 ? I tested this on aarch64 and it seems to work as expected, but then again without documentation it's hard to tell. More specifically, I created an aarch64/virt guest with several pcie-root-ports and it couldn't boot much further than GRUB when the number of ports exceeded 24, but as soon as I added the io-reserve=0 option I could get the same guest to boot fine with 32 or even 64 pcie-root-ports. I'm attaching the boot log for reference: there are a bunch of messages about the topic but they would appear to be benign. Hotplug seemed to work too: I tried with a single virtio-net-pci and I could access the network. My understanding is that PCIe devices are required to work without IO space, so this behavior matches my expectations. I wonder, though, what would happen if I had something like -device pcie-root-port,io-reserve=0,id=pci.1 -device pcie-pci-bridge,bus=pci.1 Would I be able to hotplug conventional PCI devices into the pcie-pci-bridge, or would the lack of IO space reservation for the pcie-root-port cause issues with that? -- Andrea Bolognani / Red Hat / Virtualization

[libvirt] Question about Windows builds
by Christopher Loyd Nugent 11 Jun '19

11 Jun '19

My name is Christopher Nugent. This is my first time posting to the mailing list, and I am still adjusting to the community norms. If I do anything out of line, please let me know. Anyway, on to the question: I am attempting to use libvirt in a Windows application I am developing, and came upon the following in the documentation: Libvirt is known to work as a client (not server) on Windows XP (32-bit), and Windows 7 (64-bit). I am a bit confused as to what this means. Does it mean that I won't be able to use libvirt in a host configuration, Hyper-V acting as the underlying hypervisor? I am posting to the development list because, if I am right, I would like to donate my time to amend the situation. My application will be cross-platform and will support multiple hypervisors, so using libvirt will help me not have to duplicate functionality. Thank you for your time. --Chris Nugent.

[libvirt] [PATCH]daemon: Fix a crash during virNetlinkEventServiceStopAll
by Liu Haitao 11 Jun '19

11 Jun '19

The virNetlinkEventServiceStopAll() should be executed behind virStateCleanup(), for some important resources like(static virNetlinkEventSrvPrivatePtr server) are freed unexpected. However virStateCleanup() need to use this variable(server). The call trace of virNetlinkEventServiceStopAll: virNetlinkEventServiceStopAll() --> virNetlinkEventServiceStop() --> server[protocol] = NULL; // set server to null The call trace of virStateCleanup(): virStateCleanup() -->qemuStateCleanup() -->qemuProcessStop() -->virNetDevMacVLanDeleteWithVPortProfile() -->virNetlinkEventRemoveClient() --> srv = server[protocol] In virNetlinkEventRemoveClient() the variable server is used again, but now it is null that is freed by virNetlinkEventServiceStopAll().So it would case a crash . The call trace of crash: (gdb) bt 0 __GI___pthread_mutex_lock (mutex=0x0) at /usr/src/debug/glibc/2.24-r0/git/nptl/pthread_mutex_lock.c:67 1 0x00007fb0d555d0f9 in virNetlinkEventRemoveClient () from /usr/lib64/libvirt.so.0 2 0x00007fb0d55551df in virNetDevMacVLanDeleteWithVPortProfile () from /usr/lib64/libvirt.so.0 3 0x00007fb0c1131251 in qemuProcessStop () from /usr/lib64/libvirt/connection-driver/libvirt_driver_qemu.so 4 0x00007fb0c11995ea in ??

[libvirt] [PATCH 0/4] incremental backup: QMP interactions
by Eric Blake 11 Jun '19

11 Jun '19

I'm trying to break my incremental backup work into smaller pieces so I can make progress and actually get some code committed, while I continue to hammer away at preparing a v9 series that addresses even more review comments and things learned during testing. These few patches represent the bulk of 14-15/21 from v8, except that the operation to update Checkpoint size must come later in the series when checkpoint_conf.h is ready. Another reason to commit this now, even without the incremental backup clients of the new capabilities, is that capability additions tend to be a conflict magnet, so I'd rather stabilize this and reduce the amount of rebase work I have been doing. Changes from v8: - improve testing of nbd-server-start - split up QMP changes into more manageable pieces - address formatting review comments Eric Blake (4): backup: Prepare for Unix sockets in QMP nbd-server-start backup: Add two new qemu capabilities backup: Add new qemu monitor bitmap backup: Add new parameters to qemu monitor nbd-server-add src/qemu/qemu_capabilities.h | 4 + src/qemu/qemu_monitor.h | 29 +++- src/qemu/qemu_monitor_json.h | 24 ++- src/qemu/qemu_capabilities.c | 6 + src/qemu/qemu_migration.c | 9 +- src/qemu/qemu_monitor.c | 74 ++++++++- src/qemu/qemu_monitor_json.c | 149 +++++++++++++++++- .../caps_4.0.0.aarch64.xml | 2 + .../qemucapabilitiesdata/caps_4.0.0.ppc64.xml | 2 + .../caps_4.0.0.riscv32.xml | 2 + .../caps_4.0.0.riscv64.xml | 2 + .../qemucapabilitiesdata/caps_4.0.0.s390x.xml | 2 + .../caps_4.0.0.x86_64.xml | 2 + tests/qemumonitorjsontest.c | 60 ++++++- 14 files changed, 341 insertions(+), 26 deletions(-) -- 2.20.1

[libvirt] [PATCH 0/4] test_driver: implement virDomainSaveImageGetXMLDesc and virDomainSaveImageDefineXML
by Ilias Stamatis 07 Jun '19

07 Jun '19

While implementing virDomainSaveImageGetXMLDesc and virDomainSaveImageDefineXML for the test driver, I realized that there exists already code for saving and loading test images which can be reused. However, it needed to be extracted from testDomainSaveFlags and testDomainRestoreFlags into separate functions. The new functions are inspired by the corresponding QEMU driver code where e.g. qemuDomainSaveImageOpen serves as a helper used by other functions. This series of patches initially extracts the code mentioned above into separate functions and then provides the test driver with implementations for virDomainSaveImageGetXMLDesc and virDomainSaveImageDefineXML which make use of the newly introduced functions.

[libvirt] [PATCH] qemu: Fix NULL pointer access in qemuProcessInitCpuAffinity()
by Andrea Bolognani 06 Jun '19

06 Jun '19

Commit 2f2254c7f4e5 attempted to fix a memory leak by ensuring cpumapToSet is always a freshly allocated bitmap, but regrettably introduced a NULL pointer access while doing so, because it called virBitmapCopy() without allocating the destination bitmap first. Solve the issue by using virBitmapNewCopy() instead.

[libvirt] QMP; unsigned 64-bit ints; JSON standards compliance
by Daniel P. Berrangé 05 Jun '19

05 Jun '19

The QEMU QMP service is based on JSON which is nice because that is a widely supported "standard" data format..... ....except QEMU's implementation (and indeed most impls) are not strictly standards compliant. Specifically the problem is around representing 64-bit integers, whether signed or unsigned. The JSON standard declares that largest integer is 2^53-1 and the likewise the smallest is -(2^53-1): http://www.ecma-international.org/ecma-262/6.0/index.html#sec-number.max_sa… A crazy limit inherited from its javascript origins IIUC. QEMU, and indeed many applications, want to handle 64-bit integers. The C JSON library impls have traditionally mapped integers to the data type 'long long int' which gives a min/max of -(2^63) / 2^63-1. QEMU however /really/ needs 64-bit unsigned integers, ie a max 2^64-1. Libvirt has historically used the YAJL library which uses 'long long int' and thus can't officially go beyond 2^63-1 values. Fortunately it lets libvirt get at the raw json string, so libvirt can re-parse the value to get an 'unsigned long long'. We recently tried to switch to Jansson because YAJL has a dead upstream for many years and countless unanswered bugs & patches. Unfortunately we forgot about this need for 2^64-1 max, and Jansson also uses 'long long int' and raises a fatal parse error for unsigned 64-bit values above 2^63-1. It also provides no backdoor for libvirt todo its own integer parsing. Thus we had to abort our switch to jansson as it broke parsing QEMU's JSON: https://bugzilla.redhat.com/show_bug.cgi?id=1614569 Other JSON libraries we've investigated have similar problems. I imagine the same may well be true of non-C based JOSN impls, though I've not investigated in any detail. Essentially libvirt is stuck with either using the dead YAJL library forever, or writing its own JSON parser (most likely copying QEMU's JSON code into libvirt's git). This feels like a very unappealing situation to be in as not being able to use a JSON library of our choice is loosing one of the key benefits of using a standard data format. Thus I'd like to see a solution to this to allow QMP to be reliably consumed by any JSON library that exists. I can think of some options: 1. Encode unsigned 64-bit integers as signed 64-bit integers. This follows the example that most C libraries map JSON ints to 'long long int'. This is still relying on undefined behaviour as apps don't need to support > 2^53-1. Apps would need to cast back to 'unsigned long long' for those QMP fields they know are supposed to be unsigned. 2. Encode all 64-bit integers as a pair of 32-bit integers. This is fully compliant with the JSON spec as each half is fully within the declared limits. App has to split or assemble the 2 pieces from/to a signed/unsigned 64-bit int as needed. 3. Encode all 64-bit integers as strings The application has todo all parsing/formatting client side. None of these changes are backwards compatible, so I doubt we could make the change transparently in QMP. Instead we would have to have a QMP greeting message capability where the client can request enablement of the enhanced integer handling. Any of the three options above would likely work for libvirt, but I would have a slight preference for either 2 or 3, so that we become 100% standards compliant.

[libvirt] [PATCH v2 0/7] Check TSC frequency before starting QEMU
by Jiri Denemark 03 Jun '19

03 Jun '19

Version 2: - new patches (1 and 2) fixing qemuargv2xmltest, which was probing host CPU When migrating a domain with invtsc CPU feature enabled, the TSC frequency of the destination host must match the frequency used when the domain was started on the source host or the destination host has to support TSC scaling. If the frequencies do not match and the destination host does not support TSC scaling, QEMU will fail to set the right TSC frequency when starting vCPUs on the destination and thus migration will fail. However, this is quite late since both host might have spent significant time transferring memory and perhaps even storage data. By adding the check to libvirt we can let migration fail before any data starts to be sent over. If for some reason libvirt is unable to detect the host's TSC frequency or scaling support, we'll just let QEMU try and the migration will either succeed or fail later. Luckily, we mandate TSC frequency to be explicitly set in the domain XML to even allow migration of domains with invtsc. We can just check whether the requested frequency is compatible with the current host before starting QEMU. And to let libvirt client decide whether it should even start the migration to a specific host, this series adds host's TSC frequency and scaling support to the host CPU capabilities XML. https://bugzilla.redhat.com/show_bug.cgi?id=1641702 Jiri Denemark (7): qemu: Make virQEMUCapsProbeHostCPUForEmulator more generic qemuargv2xmltest: Use mocked virQEMUCapsProbeHostCPU util: Add virHostCPUGetTscInfo conf: Report TSC frequency in host CPU capabilities cpu_x86: Fix placement of *CheckFeature functions cpu_x86: Probe TSC frequency and scaling support qemu: Check TSC frequency before starting QEMU src/conf/cpu_conf.c | 48 +++++++++++++++++++++ src/conf/cpu_conf.h | 2 + src/cpu/cpu_x86.c | 81 ++++++++++++++++++++---------------- src/qemu/qemu_capabilities.c | 14 +++---- src/qemu/qemu_capspriv.h | 5 +-- src/qemu/qemu_process.c | 53 +++++++++++++++++++++++ src/util/virhostcpu.c | 71 +++++++++++++++++++++++++++++++ src/util/virhostcpu.h | 11 +++++ tests/Makefile.am | 3 +- tests/qemuargv2xmltest.c | 3 +- tests/qemucpumock.c | 5 +-- 11 files changed, 243 insertions(+), 53 deletions(-) -- 2.21.0

[libvirt] Release of libvirt-5.4.0
by Daniel Veillard 03 Jun '19

03 Jun '19

It's out ! The release is tagged in git, and I provided signed tarball and source rpms to the usual place: https://libvirt.org/sources/ I also cut off a 5.4.0 release of the python bindings but code is same a 5.3.0 one, you can find signed tarball and source rpms at: https://libvirt.org/sources/python/ Main theme of this release is security, there is a set of advisory covered so users are invited to update, along with some improvements and bug fixes. Security: - cpu: Introduce support for the md-clear CPUID bit This bit is set when microcode provides the mechanism to invoke a flush of various exploitable CPU buffers by invoking the x86 VERW instruction. CVE-2018-12126, CVE-2018-12127, CVE-2018-12130, CVE-2019-11091. - Restrict user access to virt-admin, virtlogd and virtlockd The intended users for these facilities are the root user and the libvirtd service respectively, but these restrictions were not enforced correctly. CVE-2019-10132. Improvements: - test driver: Expand API coverage Several APIs that were missing from the test driver have now been implemented. - Avoid unnecessary static linking Most binaries shipped as part of libvirt, for example virtlogd and libvirt_iohelper, were embedding parts of the library even though they also linked against the libvirt.so dynamic library. This is no longer the case, which results in both the disk and memory footprint being reduced. - qemu: Report stat-htlb-pgalloc and stat-htlb-pgfail balloon stats These stats have been introduced in QEMU 3.0. Bug fixes: - qemu: Fix emulator scheduler support Setting the scheduler for QEMU's main thread before QEMU had a chance to start up other threads was misleading as it would affect other threads (vCPU and I/O) as well. In some particular situations this could also lead to an error when the thread for vCPU #0 was being moved to its cpu,cpuacct cgroup. This was fixed so that the scheduler for the main thread is set after QEMU starts. - apparmor: Allow hotplug of vhost-scsi devices Thanks everybody who contributed to this release, be it with bug reports, patches, reviews, docs ... Enjoy !

If for some reason libvirt is unable to detect the host's TSC frequency or scaling support, we'll just let QEMU try and the migration will either succeed or fail later. Luckily, we mandate TSC frequency to be explicitly set in the domain XML to even allow migration of domains with invtsc. We can just check whether the requested frequency is compatible with the current host before starting QEMU. And to let libvirt client decide whether it should even start the migration to a specific host, this series adds host's TSC frequency and scaling support to the host CPU capabilities XML. https://bugzilla.redhat.com/show_bug.cgi?id=1641702 Jiri Denemark (5): util: Add virHostCPUGetTscInfo conf: Report TSC frequency in host CPU capabilities cpu_x86: Fix placement of *CheckFeature functions cpu_x86: Probe TSC frequency and scaling support qemu: Check TSC frequency before starting QEMU src/conf/cpu_conf.c | 48 ++++++++++++++++++++++++ src/conf/cpu_conf.h | 2 + src/cpu/cpu_x86.c | 81 ++++++++++++++++++++++------------------- src/qemu/qemu_process.c | 53 +++++++++++++++++++++++++++ src/util/virhostcpu.c | 71 ++++++++++++++++++++++++++++++++++++ src/util/virhostcpu.h | 11 ++++++ 6 files changed, 229 insertions(+), 37 deletions(-) -- 2.21.0

[libvirt] [PATCH] virDomainSendKey: validate codeset argument
by Ilias Stamatis 03 Jun '19

03 Jun '19

This argument wasn't validated anywhere, neither in the generic implementation nor in the individual drivers. As a result a call to this function with a large enough codeset value prior to this change causes libvirtd to crash. This happens because all drivers call virKeycodeValueTranslate which uses codeset as an index to the virKeymapValues array, causing an out-of-bounds error.

This is tagged in git, I have put the signed tarball and source RPM at the usual place: https://libvirt.org/sources/ I did not build the binaries rpms, first it broke because I was still on F28 c.f. Jan's patch, and second it's true to provides little value, it's doubtful people would just install my binaries as is. Will likely stick to sources as part of releases in the future. Release looks fine in my limited testing, https://ci.centos.org/view/libvirt/ is of a rare uniform green color, which is promising too ! Please give it a try, I will likely cut RC2 on Thrusday, and then if everything goes fine push the GA over the w.e. or Monday, thanks, Daniel -- Daniel Veillard | Red Hat Developers Tools http://developer.redhat.com/ veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] Question about save and restore OVS per-port data in live migration
by wangxin (U) 31 May '19

31 May '19

Hi When we try to migrate a guest with 12 NICs, we find libvirt will try to get per-port data in finish phase, it makes the guest paused for several hundred milliseconds. qemuMigrationCookieAddNetwork -> virNetDevOpenvswitchGetMigrateData for per-nic -> run 'ovs-vsctl --if-exists get Interface vnetx external_ids:Port' (about 25ms) In our case, there's no portData available and it seems there is no need to run the cmd. Questions: 1. Is it necessary to get/set per-port data in migration finish phase? It will increase the downtime. 2. Is there any way (i.e. a switch) to not run the OVS cmd if there's no portData available?

Plan to support Resctrl Control Monitors, which is a feature introduced by kernel 'resctrl' sub-model. Submit some cleanup and refactoring patches for upcoming memory bandwidth resource monitoring (MBM) monitors. Related MBM RFC is https://www.redhat.com/archives/libvir-list/2019-April/msg01409.html. This RFC is not actively discussed since libvirt already implemented similar resctrl cache monitoring (CMT), and lots details have been discussed and implemented during the work of CMT. The cleanups and refactoring includes: 1. Removing some reluctant lines and white spaces that is existing in current code and not meet the libvirt coding style. 2. Replace 'virResctrlAllocIsEmpty' with @n==0 for indicating no resctrl allocation in configuration file. 3. Private API changes, removed 'virResctrlMonitorGetCacheOccupancy' and exported a new API named 'virResctrlMonitorGetStats' with similar functionality, but with capability to be used for retrieving MBM statistical information. 4. Refactoring 'virResctrlMonitorFreeStats' for more reusing in code. 5. Extend data structure 'virResctrlMonitorStats' with the capability to carry multiple statistical information from monitor.

[libvirt] [PATCH v3 0/6] numa: deprecate '-numa node, mem' and default memory distribution
by Igor Mammedov 28 May '19

28 May '19

Changes since v2: - taking in account previous review, implement a way for mgmt to intospect if '-numa node,mem' is supported by machine type as suggested by Daniel at https://www.mail-archive.com/qemu-devel@nongnu.org/msg601220.html * ammend "qom-list-properties" to show property values * add "numa-mem-supported" machine property to reflect if '-numa node,mem=SZ' is supported. It culd be used with '-machine none' or at runtime with --preconfig before numa memory mapping are configured * minor fixes to deprecation documentation mentioning "numa-mem-supported" property 1) "I'm considering to deprecating -mem-path/prealloc CLI options and replacing them with a single memdev Machine property to allow interested users to pick used backend for initial RAM (fixes mixed -mem-path+hostmem backends issues) and as a transition step to modeling initial RAM as a Device instead of (ab)using MemoryRegion APIs." (for more details see: https://www.mail-archive.com/qemu-devel@nongnu.org/msg596314.html) However there is a couple of roadblocks on the way (s390x and numa memory handling). I think I finally thought out a way to hack s390x in migration compatible manner, but I don't see any way to do it for -numa node,mem and default RAM assignement to nodes. Considering both numa usecases aren't meaningfully using NUMA (aside guest side testing) and could be replaced with explicitly used memdev parameter, I'd like to propose removing these fake NUMA friends on new machine types, hence this deprecation. And once the last machie type that supported the option is removed we would be able to remove option altogether. As result of removing deprecated options and replacing initial RAM allocation with 'memdev's (1), QEMU will allocate guest RAM in consistent way, fixing mixed use-case and allowing boards to move towards modelling initial RAM as Device(s). Which in its own turn should allow to cleanup NUMA/HMP/memory accounting code more by dropping ad-hoc node_mem tracking and reusing memory device enumeration instead.
