[PATCH] testutils: Terminate usage string with a new line
by Michal Privoznik 17 Jan '22

17 Jan '22

If a test binary is executed with an argument then usage information is printed out (that no arguments are accepted and what environment variables affect execution). The string is printed onto stderr but it is not terminated with a newline character producing not so nice output.

[PATCH v3 0/7] virdnsmasq: Lookup DNSMASQ in PATH
by Michal Privoznik 17 Jan '22

v3 of: https://listman.redhat.com/archives/libvir-list/2022-January/msg00386.html diff to v2: - Make dnsmasqCapsGetBinaryPath() fail if dnsmasq is not found - Change the way caps are constructed in networkxml2conftest - More code cleanup However, as I was going through the code I realized that what we really do is check dnsmasq's version against the minimal required one (2.67). No actual capabilities are parsed. This is due to cleanup merged earlier this release (v8.0.0-rc1~138 and commits around). While we could drop more code I figured it may be worth keeping it for future use. I mean, one day we might want to have an capability for give feature.

[PATCH v2] libselinux: Strip spaces before values in config

Spaces before values in /etc/selinux/config should be ignored just as spaces after them are. E.g. "SELINUXTYPE= targeted" should be a valid value.

[PATCH 0/3] qemu: Add caps for qemu-7.0 dev cycle and re-enable JSON for -device
by Peter Krempa 17 Jan '22

17 Jan '22

Note that I've truncated the auto-generated stuff out of patches 2/3 and 3/3. For full version: git fetch https://gitlab.com/pipo.sk/libvirt.git device-json-reenable Also note that I've based this on the 'staging' branch of qemu.git currently, which means that there's a small possibility that the pull request will be rejected. I'll make sure to verify that before pushing.

[RFC 0/1] qemu: update index for serial device using taget.port
by divya 14 Jan '22

14 Jan '22

Issue ----- The port being provided in the xml file of the domain is not being used for the creation of qemu command. On adding the serial device : <serial> <target type='serial' port='3'/> </serial> Generated qemu command will look like : /usr/libexec/qemu-kvm ...\ -device isa-serial,chardev=charserial0,id=serial0 Actually it should be : /usr/libexec/qemu-kvm ...\ -device isa-serial,chardev=charserial0,id=serial0,index=3 Patch ----- Out already for the correction : https://listman.redhat.com/archives/libvir-list/2018-April/msg02302.html This patch was not followed up. According to me there are multiple reasons Reasons for not following up ---------------------------- Index : specifies the index number of a connector port. If not specified, the index is automatically incremented. This logic exists both on qemu as well as libvirt. https://github.com/qemu/qemu/blob/master/hw/char/serial-isa.c#L62 Issue 1: If we want two isa-serial devices and for the first one is we mention the port to be 3, then for the next device it not automatically assign the port number 4 which will throw the following error : error: internal error: process exited while connecting to monitor: 2021-11-12T11:05:31.169987Z qemu-kvm: -device isa-serial,chardev=charserial2,id=serial2,index=5: Max. supported number of ISA serial ports is 4. But we are left with 3 ports (0,1,2) which are unused. So ideally we should have used them. Issue 2: It is possible that two devices get the same port address which might lead to a lot of ambiguity. Example: we want two devices and for the second one we provide the index 0. Then from default logic the first device will be allotted port 0 and the second device will overwrite it and get port 0. Solution : ---------- Port allocation logic 1. Precedence should be given to serial devices as we only have the first 4 ports for them. 1.1. Check the command line/xml file, scan for all the devices mentioned and then start with the isa-serial devices for port allocation. 2.Maintain a buffer(bitmap) for marking the allocated ports. 3.While assigning a port to the device 3.1. If no port is provided by the user : provide the next available port. 3.2. Else check: 3.2.1. If the port is already allocated : throw the error. 3.2.2. Else allocate the port. 3.3. If out of ports : throw error -> qemu throws the error. Libvirt manages the port numbers with the similar logic(auto increment) along with the above mentioned bug. Hence need to add the above patch along with the Port allocation logic. root (1): update index for serial device using taget.port src/conf/domain_conf.c | 70 +++++++++++++++++-- src/qemu/qemu_command.c | 20 ++++-- tests/qemuhotplugtest.c | 1 - ...g-console-compat-2-live+console-virtio.xml | 4 +- .../qemuhotplug-console-compat-2-live.xml | 4 +- tests/qemuxml2argvdata/bios.args | 2 +- .../qemuxml2argvdata/console-compat-auto.args | 2 +- .../console-compat-chardev.args | 2 +- tests/qemuxml2argvdata/console-compat.args | 2 +- .../qemuxml2argvdata/console-virtio-many.args | 2 +- tests/qemuxml2argvdata/controller-order.args | 2 +- .../name-escape.x86_64-2.11.0.args | 4 +- tests/qemuxml2argvdata/name-escape.xml | 1 + .../q35-virt-manager-basic.args | 2 +- .../serial-dev-chardev-iobase.args | 2 +- .../qemuxml2argvdata/serial-dev-chardev.args | 2 +- .../qemuxml2argvdata/serial-file-chardev.args | 2 +- tests/qemuxml2argvdata/serial-file-log.args | 2 +- .../qemuxml2argvdata/serial-many-chardev.args | 4 +- .../qemuxml2argvdata/serial-pty-chardev.args | 2 +- tests/qemuxml2argvdata/serial-spiceport.args | 2 +- .../qemuxml2argvdata/serial-tcp-chardev.args | 2 +- .../serial-tcp-telnet-chardev.args | 2 +- .../serial-tcp-tlsx509-chardev-notls.args | 8 ++- .../serial-tcp-tlsx509-chardev-notls.xml | 18 ++++- .../serial-tcp-tlsx509-chardev-verify.args | 4 +- .../serial-tcp-tlsx509-chardev-verify.xml | 2 +- .../serial-tcp-tlsx509-chardev.args | 4 +- .../serial-tcp-tlsx509-chardev.xml | 2 +- .../serial-tcp-tlsx509-secret-chardev.args | 4 +- .../serial-tcp-tlsx509-secret-chardev.xml | 2 +- .../qemuxml2argvdata/serial-udp-chardev.args | 4 +- .../qemuxml2argvdata/serial-unix-chardev.args | 4 +- .../serial-unix-chardev.x86_64-latest.args | 4 +- tests/qemuxml2argvdata/serial-vc-chardev.args | 2 +- tests/qemuxml2argvdata/user-aliases.args | 4 +- .../virtio-9p-createmode.x86_64-latest.args | 2 +- .../virtio-9p-multidevs.x86_64-latest.args | 2 +- .../x86_64-pc-graphics.x86_64-latest.args | 2 +- .../x86_64-pc-headless.x86_64-latest.args | 2 +- .../x86_64-q35-graphics.x86_64-latest.args | 2 +- .../x86_64-q35-headless.x86_64-latest.args | 2 +- .../serial-tcp-tlsx509-chardev.xml | 2 +- 43 files changed, 149 insertions(+), 65 deletions(-) -- 2.27.0

[PATCH] tests: Report expected monitor command for simulated commands
by Michal Privoznik 14 Jan '22

14 Jan '22

There are two tests currently that simulate QMP talk: qemucapabilitiestest and qemuhotplugtest. In both cases they check whether currently executed command is the one for which reply was provided. If not an error message is reported. However, the error message contains only the actual command and not the expected one. This makes it harder to navigate through .replies files.

Release of libvirt-8.0.0
by Jiri Denemark 14 Jan '22

14 Jan '22

The 8.0.0 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 feedback. Your work is greatly appreciated. * Security * libxl: Fix potential deadlock and crash (CVE-2021-4147) A rogue guest could continuously reboot itself and cause libvirtd on the host to deadlock or crash, resulting in a denial of service condition. * Removed features * qemu: Explicitly forbid live changing nodeset for strict numatune For ``strict`` mode of <numatune/> it can't be guaranteed that memory is moved completely onto new set of nodes (e.g. QEMU might have locked pieces of its memory) thus breaking the strict promise. If live migration of QEMU memory between NUMA nodes is desired, users are advised to use ``restrictive`` mode instead. * New features * qemu: Synchronous write mode for disk copy operations The ``blockdev-mirror`` block job supports a mode where writes from the VM are synchronously propagated to the destination of the copy. This ensures that the job will converge under heavy I/O. Implement the mode for the copy blockjob as ``VIR_DOMAIN_BLOCK_COPY_SYNCHRONOUS_WRITES`` flag exposed via ``virsh blockcopy --synchronous-writes`` and for non-shared storage migration as ``VIR_MIGRATE_NON_SHARED_SYNCHRONOUS_WRITES`` exposed via ``virsh migrate --copy-storage-synchronous-writes``. * Introduce TCG domain features Libvirt is now able to set the size of translation block cache size (tb-size) for TCG domains. * qemu: Add new API to inject a launch secret in a domain New API ``virDomainSetLaunchSecurityState()`` and virsh command ``domsetlaunchsecstate`` are added to support injecting a launch secret in a domain's memory. * Improvements * libxl: Implement the virDomainGetMessages API * qemu: Preserve qcow2 sub-cluster allocation state after external snapshots and block-copy The new image which is installed as an overlay on top of the current chain when taking an external snapshot, or the target of a block copy operation now enables sub-cluster allocation (``extended_l2``) if the original image has the option enabled. * Bug fixes * qemu: Fix device hot-unplug with ``libvirt-7.9`` or ``libvirt-7.10`` used with ``qemu-6.2`` An internal change to the configuration format used by the above libvirt versions triggers a bug in ``qemu-6.2`` where qemu no longer emits the event notifying that the device was unplugged successfully and thus libvirt never removes the device from the definition. This impacts only devices which were present at startup of the VM, hotplugged devices behave correctly. This is fixed in ``libvirt-8.0`` by reverting to the old configuration approach until qemu is fixed. As a workaround for ``libvirt-7.9`` and ``libvirt-7.10`` the old configuration approach can be forced by: Option 1, global ``qemu.conf``:: capability_filters = [ "device.json" ] Option 2, per VM XML override:: <domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'> [...] <qemu:capabilities> <qemu:del capability='device.json'/> </qemu:capabilities> </domain> * Fix sparse streams with split daemon In split daemon scenario, a client connected to a hypervisor driver and using sparse streams (e.g. ``virsh vol-download --sparse``) would make the hypervisor daemon enter an infinite loop without any data transfer. This is now fixed. * Build no longer requires RPC library Code and its cross dependencies were fixed so that build without remote driver and thus an RPC library (like ``tirpc``) fails no more. * virnetdevopenvswitch: Fix 'burst' value passed to ovs-vsctl When a ``<bandwidth/>`` was defined for a TAP device that's plugged into an OvS bridge values passed to the OvS were incorrectly recalculated resulting in slightly different limits being applied. Enjoy. Jirka

[PATCH] rpc: Emit a warning when applying RPC throttling
by Ivan Teterevkov 13 Jan '22

13 Jan '22

Whenever the number of outstanding requests being served reaches max_client_requests, the RPC server applies RX throttling and temporarily stops receiving incoming data. Consequently, it stops receiving the keep-alive responses from the client and eventually may cause a connection timeout on the server-side. This patch emits a warning message in such cases so that the users may root-cause the connection timeout and reconfigure max_client_requests depending on their application.

[PATCH for 8.0 0/3] Fix creation of snapshots without libvirt metadata
by Peter Krempa 12 Jan '22

12 Jan '22

After a recent unreleased refactor we don't remove the temporary snapshot object from the list when finishing a snapshot without metadata thus we should fix it before releasing a buggy release.

[PATCH v4] report error when virProcessGetStatInfo() is unable to parse data
by Ani Sinha 12 Jan '22

12 Jan '22

Currently virProcessGetStatInfo() always returns success and only logs error when it is unable to parse the data. Make this function actually report the error and return a negative value in this error scenario. Fix the callers so that they do not override the error generated. Also fix non-linux implementation of this function so as to report error.
