[libvirt PATCH] docs: introduce stubs for new libvirt Go packages
by Daniel P. Berrangé 01 Jun '21

01 Jun '21

Currently we expose libvirt Go packages at libvirt.org/libvirt-go libvirt.org/libvirt-go-xml These packages have not supported Go modules historically and when we tried to introduce modules, we hit the problem that we're not using semver for versioning. The only way around this is to introduce new packages under a different namespace, that will have the exact same code, but be tagged with a different version numbering scheme. This change proposes: libvirt.org/go/libvirt libvirt.org/go/libvirtxml Note the hyphen is removed so that the import basename matches the Go package name. Signed-off-by: Daniel P. Berrangé <berrange(a)redhat.com> --- The corresponding repos exist https://gitlab.com/libvirt/libvirt-go-module https://gitlab.com/libvirt/libvirt-go-xml-module but I'm leaving them empty until we've completed this release, then I'll populate with content matching 7.4.0, minus the existing tags.

by Jiri Denemark 27 May '21

27 May '21

I have just tagged v7.4.0-rc1 in the repository and pushed signed tarballs and source RPMs to https://libvirt.org/sources/ Please give the release candidate some testing and in case you find a serious issue which should have a fix in the upcoming release, feel free to reply to this thread to make sure the issue is more visible. If you have not done so yet, please update NEWS.rst to document any significant change you made since the last release. Thanks, Jirka

[libvirt PATCH 0/2] Revert mdev autostart support
by Jonathon Jongsma 27 May '21

27 May '21

As Daniel Berrange mentioned, the method of supporting autostart for node devices was not consistent with other libvirt objects. This patch series reverts this feature before it gets into a release. I will submit a follow-up patch soon which adds the feature back with a consistent API.

[PATCH V5] libxl: adjust handling of libxl_device_nic objects
by Jim Fehlig 26 May '21

26 May '21

libxl objects are supposed to be initialized and disposed. Adjust libxlMakeNic to use an already initialized object owned by the caller. Adjust libxlMakeNicList to initialize the list of objects, before they are filled by libxlMakeNic. The libxl_domain_config object passed to libxlMakeNicList is owned by the caller and will be disposed with libxl_domain_config_dispose, which also disposes embedded objects such as libxl_device_nic.
