[libvirt PATCH 0/2] cpu_conf: Format vendor_id for host-model CPUs
by Jiri Denemark 19 Feb '20

19 Feb '20

In commit v5.9.0-400-gaf8e39921a I removed printing model's fallback and vendor_id attributes when no model is specified. However, vendor_id makes sense even without a specific CPU model (for host-model CPUs). https://bugzilla.redhat.com/show_bug.cgi?id=1804549 Jiri Denemark (2): qemuxml2xmltest: Add case for host-model vendor_id cpu_conf: Format vendor_id for host-model CPUs src/conf/cpu_conf.c | 14 +++++---- .../cpu-host-model-vendor.xml | 30 +++++++++++++++++++ tests/qemuxml2xmltest.c | 1 + 3 files changed, 40 insertions(+), 5 deletions(-) create mode 100644 tests/qemuxml2xmloutdata/cpu-host-model-vendor.xml -- 2.25.0

virtlogd spinning on 100% CPU with the latest libvirt

Build libvirt from git (ccf7567329f). Using the libvirt ‘run’ script, run something like libguestfs-test-tool. I think basically any command which runs a guest will do. NB These commands are all run as NON-root: killall libvirtd lt-libvirtd virtlogd lt-virtlogd ./build/run libguestfs-test-tool Now there will be a lt-virtlogd process using 100% of CPU: PID USER PR NI

[libvirt PATCH v2 0/6] qemu: add stricter checks of permissibility of the QoS parameter 'floor'
by Pavel Mores 17 Feb '20

17 Feb '20

v2 is mostly just integrating requests from Michal's review. The initial two commits introduce new utility functions to be used in the following two commits. The final two commits have no substantial changes since v1. The only exception are long lines caused by error messages which stay unbroken in v2 as per libvirt's contributor's guidelines (as was also pointed out during review). Pavel Mores (6): qemu: test if bandwidth has 'floor' factored out to separate function qemu: add function to test if network supports setting 'floor' qemu: fail on attempt to set 'floor' if interface type is not 'network' qemu: check if 'floor' is supported for given interface and network qemu: call networkPlugBandwidth() for all types of network docs: QoS parameter 'floor' is supported for 'open' networks too docs/formatnetwork.html.in | 2 +- src/conf/netdev_bandwidth_conf.h | 27 +++++++++++++++++++++++++++ src/network/bridge_driver.c | 27 +++++++++++++++++++-------- src/qemu/qemu_driver.c | 18 +++++++++++++++--- 4 files changed, 62 insertions(+), 12 deletions(-) -- 2.24.1

[rust PATCH] Implement virStoragePoolListAllVolumes and virStoragePoolListVolumes for StoragePool
by mathias＠pius.io 15 Feb '20

15 Feb '20

From: Mathias Pius <mathias(a)pius.io> Now as a single patch, and with Signed-off-by tag in accordance with DCO. This patch implements virStoragePoolListAllVolumes and virStoragePoolListVolumes for the StoragePool object. I'm not too familiar with the libvirt codebase, so I've used similar functions from connect.rs and domain.rs for so the implementations should (hopefully) be as correct as those. I've taken the liberty of using Vec::with_capacity when allocating vectors to store the result of these operations in, to prevent reallocations while converting the object types from the internal type to StorageVol and Strings.

Questions about using qemuProcess API within a libvirt test
by Collin Walling 14 Feb '20

14 Feb '20

Hello, I am working on implementing libvirt test cases for the hypervisor-cpu-compare and -baseline commands. Ideally, I would like to take advantage of the qemuProcess API to spin up a QEMU instance and run these commands to test real data queried from the hypervisor. However, I am having issues with my libvirt tests communicating with a QEMU instance. The API can successfully spin an instance, but no commands can be sent to QEMU -- not even the qmp_capabilities handshake. The test case hangs forever with no indication that something went wrong. The hang occurs specifically within the qemuProcessQMPLaunch phase of the qemuProcessQMPStart function. Eventually the libvirt API will get to qemuMonitorSend, and at this loop... while (!mon->msg->finished) { if (virCondWait(&mon->notify, &mon->parent.lock) < 0) { virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("Unable to wait on monitor condition")); goto cleanup; } } ...the program will hang at conditional wait. I kept the QEMU instance alive after killing my test and connected to the monitor socket that was still lingering. The qmp_capabilities command was never sent, thus leading me to believe that the libvirt tests cannot communicate with a QEMU instance. As s390x is currently the only arch to have implemented these commands, I believe it would be beneficial to have an easy way to test both the expected QEMU response and libvirt parsing within a single test case if/when other archs decide to implement these commands. I'd like to ask two questions: 1: does it make sense for libvirt tests to communicate with an external binary (specifically QEMU)? 2: if so, is there some sort of conflict between a libvirt test and a QEMU binary? I afraid to say that I am at a loss how to repair this or perhaps how to use the API properly. I appreciate anyone's help with looking into this. Note: in case I am not clear, by "libvirt test" I am referring to a test implemented in the tests directory of the libvirt project. -- Respectfully, - Collin Walling
