[PATCH v2 0/5] logging: add log cleanup for obsolete domains
by Oleg Vasilev 30 Jan '23

30 Jan '23

Presently, logs from deleted domains remain forever. Particular motivation comes from the case when libguestfs has repeatedly created transient VMs, which in turn created plenty of logs. This takes up space and lots of files troubles filesystem navigation. More motivation in [1]. Patch solving same problem in [2]. Changes in v2: substantial rework according to Martin Kletzander's comments v1: https://www.mail-archive.com/libvir-list@redhat.com/msg233754.html [1]: https://listman.redhat.com/archives/libvir-list/2022-February/228149.html [2]: https://listman.redhat.com/archives/libvir-list/2022-February/msg00865.html CC: Martin Kletzander <mkletzan(a)redhat.com> Oleg Vasilev (5): logging: refactor to store config inside log handler logging: move virLogHandler to header logging: add configuration for future log cleaner logging: add log cleanup for obsolete domains logging: use the log cleaner po/POTFILES | 1 + src/logging/log_cleaner.c | 276 +++++++++++++++++++++++++++++++ src/logging/log_cleaner.h | 29 ++++ src/logging/log_daemon.c | 6 +- src/logging/log_daemon_config.c | 9 + src/logging/log_daemon_config.h | 3 + src/logging/log_handler.c | 64 +++---- src/logging/log_handler.h | 50 ++++-- src/logging/meson.build | 1 + src/logging/test_virtlogd.aug.in | 2 + src/logging/virtlogd.aug | 2 + src/logging/virtlogd.conf | 14 ++ 12 files changed, 399 insertions(+), 58 deletions(-) create mode 100644 src/logging/log_cleaner.c create mode 100644 src/logging/log_cleaner.h -- 2.38.1

Re: [PATCH] qemu: implement QEMU NBD source reconnect delay attribute
by Christian Nautze 30 Jan '23

30 Jan '23

Hi! Is it possible to get a review on this patch I send before Christmas? :) Thank you! Christian _____________________________________________________ Currently it's only possible to set this parameter during domain creation via QEMU commandline passthrough feature. With the new delay attribute it's also possible to set this parameter if you want to attach a new NBD disk using "virsh attach-device domain device.xml" e.g.: <disk type='network' device='disk'> <driver name='qemu' type='raw'/> <source protocol='nbd' name='foo'> <host name='example.org' port='6000'/> <reconnect enabled='yes' delay='10'/> </source> <target dev='vdb' bus='virtio'/> </disk> Signed-off-by: Christian Nautze <christian.nautze at exoscale.ch <https://listman.redhat.com/mailman/listinfo/libvir-list>> --- docs/formatdomain.rst | 10 ++++++-- src/conf/domain_conf.c | 19 +++++++++++++++ src/conf/schemas/domaincommon.rng | 3 +++ src/conf/schemas/storagecommon.rng | 5 ++++ src/conf/storage_source_conf.c | 1 + src/conf/storage_source_conf.h | 4 ++++ src/qemu/qemu_block.c | 4 +++- src/qemu/qemu_domain.c | 9 ++++++++ .../disk-network-nbd.x86_64-latest.args | 23 +++++++++++-------- tests/qemuxml2argvdata/disk-network-nbd.xml | 8 +++++++ tests/qemuxml2xmloutdata/disk-network-nbd.xml | 9 ++++++++ 11 files changed, 82 insertions(+), 13 deletions(-) diff --git a/docs/formatdomain.rst b/docs/formatdomain.rst index d7fffc6e0b..3fbeba644a 100644 --- a/docs/formatdomain.rst +++ b/docs/formatdomain.rst @@ -2938,13 +2938,19 @@ paravirtualized driver is specified via the ``disk`` element. are intended to be default, then the entire element may be omitted. ``reconnect`` For disk type ``vhostuser`` configures reconnect timeout if the connection - is lost.

As long as the pinned limitation has its own bucket it is probably fine? The underlying memory allocations should have already been charged to the memcg - so we don't want to double account. Alex and Daniel were looking at this from the qemu/libvirt perspective, perhaps they have some insight what they would like to see? Thanks, Jason

[PATCH] virsh: Make domif-setlink work more than once
by Michal Privoznik 30 Jan '23

30 Jan '23

In virsh, we have this convenient domif-setlink command, which is just a wrapper over virDomainUpdateDeviceFlags() and which allows setting link state of given guest NIC. It does so by fetching corresponding <interface/> XML snippet and either putting <link state=''/> into it, OR if the element already exists setting the attribute to desired value. The XML is then fed into the update API. There's, however, a small bug in detecting the pre-existence of the element and its attribute. The code looks at "link" attribute, while in fact, the attribute is called "state".

From: Or Ozeri <oro(a)il.ibm.com> Previous commit added support for active RBD disk snapshots, using the same qmp_transaction used also for external snapshots. The same transaction can be used to mix internal and external snapshots. To allow this, this commit simply removes the check that disallows mixing for active snapshots.

[PATCH v2 3/6] qemu: Add internal support for active disk internal snapshots
by ORO＠il.ibm.com 29 Jan '23

29 Jan '23

From: Or Ozeri <oro(a)il.ibm.com> libvirt supports taking external disk snapshots on a running VM, using qemu's "blockdev-snapshot" command. qemu also supports "blockdev-snapshot-internal-sync" to do the same for internal snapshots. This commit wraps this (old) qemu capability to allow future libvirt users to take internal disk snapshots on a running VM. This will only work for disk types which support internal snapshots, and thus we require the disk type to be part of a white list of known types. For this commit, the list of supported formats is empty. An upcoming commit will allow RBD disks to use this new capability.

[PATCH] rpc: Use struct zero initializer for args
by Michal Privoznik 26 Jan '23

26 Jan '23

In a recent commit of v9.0.0-104-g0211e430a8 I've turned all args vars in src/remote/remote_driver.c to be initialized wit {0}. What I've missed was the generated code. Do what we've done in v9.0.0-13-g1c656836e3 and init also args, not just ret.

[PATCH] remote: Initialize args variable
by Michal Privoznik 26 Jan '23

26 Jan '23

Recently, in v9.0.0-7-gb2034bb04c we've dropped initialization of @args variable. The reasoning was that eventually, all members of the variable will be set. Well, this is not correct. For instance, in remoteConnectGetAllDomainStats() the args.doms.doms_val pointer is set iff @ndoms != 0. However, regardless of that, the pointer is then passed to VIR_FREE(). Worse, the whole args is passed to xdr_remote_connect_get_all_domain_stats_args() which then calls xdr_array, which tests the (uninitialized) pointer against NULL. This effectively reverts b2034bb04c61c75ddbfbed46879d641b6f8ca8dc.

[libvirt PATCH 0/7] Extract the integration job commands to a shell scripts
by Erik Skultety 26 Jan '23

26 Jan '23

Using shell scripts rather than inlining shell commands to YAML feels more natural, more readable, and will keep all different variations of execution consistent. Essentially the only disadvantage is that we won't see each command listed one-by-one in gitlab's log output (unless we set -x that is), but given that shell would complain if something was wrong with the script, it's fairly easy to identify the problem. Here's a successful pipeline after the change: https://gitlab.com/eskultety/libvirt/-/pipelines/753090691 Erik Skultety (7): ci: integration: Extract several hidden job definitions to a script ci: integration: Drop the 'install-deps' hidden job and reference ci: integration-template: Drop Fedora 35 check ci: integration.sh: Replace most 'sudo' usage with running as root ci: integration.sh: Add/Rewrite/Reformat commentaries ci: integration.sh: Replace 'test' with '[' operator ci: integration.sh: Define the SCRATCH_DIR variable for local execution ci/integration-template.yml | 42 ++---------------------------- ci/integration.sh | 51 +++++++++++++++++++++++++++++++++++++ 2 files changed, 53 insertions(+), 40 deletions(-) create mode 100644 ci/integration.sh -- 2.39.0

[PATCH v2 0/5] Support crypto device
by zhenwei pi 25 Jan '23

25 Jan '23

v1 -> v2: - Rebase code against the latest commit: 46aee2a9255adf842ab44a9292acb46189a726f7 - Merge previous 1/7 and 2/7 into a single patch: conf: introduce crypto device - Add missing qemuxml2xmltest. - Merge previous 3/7 and 4/7 into a single patch: capabilities: introduce crypto - Add missing formatdomaincaps.rst. - Several fixes from Michal Prívozník' crypto_review branch. - Add caps and test for qemu-8.0. Thanks to Michal for lots of suggestions! v1: This series supports crypto device, also add support for QEMU. The basic xml schema looks like: <crypto model='virtio' type='qemu'> <backend model='builtin' queues='1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x0a' function='0x0'/> </crypto> <crypto model='virtio' type='qemu'> <backend model='lkcf'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x0b' function='0x0'/> </crypto> Each patch has been tested by 'ninja -C build test', and launch a QEMU with crypto devices, it works fine. zhenwei pi (5): conf: introduce crypto device capabilities: introduce crypto qemu: alias: support crypto device qemu: command: support crypto device

[libvirt PATCH] rpc: don't try to spawn non-existant daemon
by Daniel P. Berrangé 25 Jan '23

25 Jan '23

If libvirt is built in client only mode, the libvirtd/virtqemud/etc daemons won't exist. If the client is told to connect to a local hypervisor, it'll see the socket doesn't exist, try to spawn the daemon and then re-try connecting to the socket for a few seconds. Ultimately this will fail because the daemon doesn't exist and the user gets an error message error: Failed to connect socket to '/run/user/1000/libvirt/virtqemud-sock': No such file or directory technically this is accurate, but it doesn't help identify the root cause. With this change it will now report error: binary 'virtqemud' does not exist in $PATH: No such file or directory and will skip all the socket connect retries Signed-off-by: Daniel P.

[PATCH 0/3] update RISC-V QEMU caps for QEMU 8.0.0
by Daniel Henrique Barboza 24 Jan '23

24 Jan '23

Hi, This series updates RISC-V QEMU caps that weren't being updated since QEMU 5.0.0. To do that I had to add a RISC-V stub driver in src/cpu to avoid test failures after the caps update. This is a very bare-bone driver that is basically a no-op. I also took the opportunity to enable the RISC-V 'virt' machine type in domaincapstest.c to increase the test coverage for the architecture.

[PATCH] rpc: Fix error message in virNetServerSetClientLimits
by Martin Kletzander 24 Jan '23

24 Jan '23

Commit f007940cb25a tried to change the error message so that it is unified later in 35afa1d2d6c1, but various rewrites missed this particular error message which does not make sense. Fix it so that it is the same as the other two messages checking the same thing in this file.

[PATCH] network: Increase max route size when checking IPv6 forwarding
by Brooks Swinnerton 24 Jan '23

24 Jan '23

In d9ee51e, virNetDevIPCheckIPv6Forwarding was updated to walk the contents of /proc/net/ipv6_route so that it could check to see if the RTF_ADDRCONF was set on any IPv6 routes to ultimately determine if enabling forwarding would result in an error due to accept_ra=1 being set on the interface. The implementation added in that commit limited the number of routes that could be read from /proc/net/ipv6_route to 100_000, each with 150 characters. This is problematic for machines that have a full IPv6 routing table, as the IPv6 routing table has now grown to over 160_000 (it was closer to 100_000 at the time of that commit). This patch increases the maximum route size from 100_000 to 1_000_000. While a million routes is somewhat arbitrary, it's meant to be a value that can be supported for the forseeable future. APNIC, one of the five regional internet registries, recently published a forecast of IPv6 table growth which anticipates a worst-case growth to 1_000_000 in January of 2029.
