[libvirt] [PATCH] Fix python error reporting for some storage operations
by Cole Robinson 07 Mar '25

07 Mar '25

In the python bindings, all vir* classes expect to be passed a virConnect object when instantiated. Before the storage stuff, these classes were only instantiated in virConnect methods, so the generator is hardcoded to pass 'self' as the connection instance to these classes. Problem is there are some methods that return pool or vol instances which aren't called from virConnect: you can lookup a storage volume's associated pool, and can lookup volumes from a pool. In these cases passing 'self' doesn't give the vir* instance a connection, so when it comes time to raise an exception crap hits the fan. Rather than rework the generator to accomodate this edge case, I just fixed the init functions for virStorage* to pull the associated connection out of the passed value if it's not a virConnect instance.

[libvirt] Supporting vhost-net and macvtap in libvirt for QEMU
by Anthony Liguori 27 Oct '23

27 Oct '23

Disclaimer: I am neither an SR-IOV nor a vhost-net expert, but I've CC'd people that are who can throw tomatoes at me for getting bits wrong :-) I wanted to start a discussion about supporting vhost-net in libvirt. vhost-net has not yet been merged into qemu but I expect it will be soon so it's a good time to start this discussion. There are two modes worth supporting for vhost-net in libvirt. The first mode is where vhost-net backs to a tun/tap device. This is behaves in very much the same way that -net tap behaves in qemu today. Basically, the difference is that the virtio backend is in the kernel instead of in qemu so there should be some performance improvement. Current, libvirt invokes qemu with -net tap,fd=X where X is an already open fd to a tun/tap device. I suspect that after we merge vhost-net, libvirt could support vhost-net in this mode by just doing -net vhost,fd=X. I think the only real question for libvirt is whether to provide a user visible switch to use vhost or to just always use vhost when it's available and it makes sense. Personally, I think the later makes sense. The more interesting invocation of vhost-net though is one where the vhost-net device backs directly to a physical network card. In this mode, vhost should get considerably better performance than the current implementation. I don't know the syntax yet, but I think it's reasonable to assume that it will look something like -net tap,dev=eth0. The effect will be that eth0 is dedicated to the guest. On most modern systems, there is a small number of network devices so this model is not all that useful except when dealing with SR-IOV adapters. In that case, each physical device can be exposed as many virtual devices (VFs). There are a few restrictions here though. The biggest is that currently, you can only change the number of VFs by reloading a kernel module so it's really a parameter that must be set at startup time. I think there are a few ways libvirt could support vhost-net in this second mode. The simplest would be to introduce a new tag similar to <source network='br0'>. In fact, if you probed the device type for the network parameter, you could probably do something like <source network='eth0'> and have it Just Work. Another model would be to have libvirt see an SR-IOV adapter as a network pool whereas it handled all of the VF management. Considering how inflexible SR-IOV is today, I'm not sure whether this is the best model. Has anyone put any more thought into this problem or how this should be modeled in libvirt? Michael, could you share your current thinking for -net syntax? -- Regards, Anthony Liguori

[libvirt] [python] WIP-FYI: mypy annotations for libvirt-python
by Philipp Hahn 20 Apr '20

20 Apr '20

Hello, Maybe you already have heads about mypy <http://mypy-lang.org/>, which "is an experimental optional static type checker for Python that aims to combine the benefits of dynamic (or "duck") typing and static typing". I started to write a manual annotation file for the Python binding of libvirt. I've attached my current version, so others can benefit from it, too. It is far from complete, but it already helped my to find some errors in my code. (My latest version is also available at <https://github.com/univention/typeshed/blob/libvirt/third_party/2and3/libvi…>) Long-term it probably would be better to teach the Python binding "generator.py" to add the type information (PEP 484 <https://www.python.org/dev/peps/pep-0484/>) directly into the generated "libvirt.py" file, but that's for another day. If someone else is interested in helping with that, please feel free to get in contact. Philipp -- Philipp Hahn Open Source Software Engineer Univention GmbH be open.

[libvirt] [PATCH 0/3] Fix ppc64 CPU configuration for QEMU 2.11+
by Jiri Denemark 08 Oct '19

08 Oct '19

The original fix was both incomplete and too general. It only fixed domain startup, but libvirt would still report empty list of supported CPU models with recent QEMU for ppc64. On the other hand, while ppc64 QEMU ignores case when looking up CPU model names, x86_64 QEMU does case sensitive lookup.

[libvirt] [PATCH v6 00/33] BaselineHypervisorCPU using QEMU QMP exchanges
by Chris Venteicher 02 Apr '19

02 Apr '19

Some architectures (S390) depend on QEMU to compute baseline CPU model and expand a models feature set. Interacting with QEMU requires starting the QEMU process and completing one or more query-cpu-model-baseline QMP exchanges with QEMU in addition to a query-cpu-model-expansion QMP exchange to expand all features in the model. See "s390x CPU models: exposing features" patch set on Qemu-devel for discussion of QEMU aspects.

[libvirt] [PATCH v2 00/25] qemu: virtio-{non-}transitional support
by Cole Robinson 15 Mar '19

15 Mar '19

v1 libvirt patches: https://www.redhat.com/archives/libvir-list/2019-January/msg00593.html Previous incomplete RFC here: https://www.redhat.com/archives/libvir-list/2019-January/msg00346.html qemu patches, queued for qemu 4.0.0: https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg00923.html Previous libvirt discussion around this: https://www.redhat.com/archives/libvir-list/2018-August/msg01073.html Long story short we need to expose these options so apps have a usable way to support rhel6 + virtio + q35. This series exposes the new devices as model= values. This required adding new model= attributes for several devices. See v1 posting for a summary of the XML changes introduced, mostly it's adding virtio-transitional and virtio-non-transitional to existing model= enums, and adding model= XML attributes for devices that don't have them (disk, fs, input) Changes from v1: - <filesystem> models are now named virtio-9p, virtio-9p-transitional, virtio-9p-non-transitional. This is to avoid ambiguity as in the near future we will likely add virtio-fs <filesystem> support - Cleanup and prep work is separated into separate patches and front loaded into the series. - qemu caps additions are separated from the qemu_command.c patches, and squashed together upfront. - virDomainDeviceSetData is added to make it easier to compose a virDomainDeviceDef on the fly. This is used for the transitional cli building but can be useful elsewhere too, but that's for another series. - Lots of small improvements and fixes suggested by Andrea.
