[libvirt] [RFC PATCH 0/8] Introduce the virDomainDefineJSONFlags() public API
by Andrea Bolognani 01 Apr '19

01 Apr '19

Back in 2005, when the libvirt project was started, XML was pretty much the only sensible, widely used format one could use to store structured data. A lot has changed since then, and these days you'd be hard pressed to find any API that does not use JSON for encoding information; in fact, we already use JSON heavily inside libvirt, for example to communicate with QEMU processes through QMP or store configuration data for use by the libvirt NSS plugin. The reasons for JSON's success over XML are plain to see: you get the same nicely structured data, but none of the ugly angle brackets or annoying repetition caused by having to both open *and* close elements explicitly; additionally, you get support for extremely useful and common data structures such as lists and dictionary out of the box, and even properly typed strings and numbers. It's just an overall much better data representation language. This RFC series provides the initial, very basic (yet fully functional) implementation of a JSON-based alternative to the existing virDomainDefineXML(); over time, we would introduce similar APIs for defining libvirt objects other than domains, such as for example networks. Once enough time has passed, we might even consider removing the XML-based APIs altogether and drop the XML parsing code along with our libxml2 dependency, making libvirt much leaner in the process.

[libvirt] Entering freeze for libvirt-5.2.0
by Daniel Veillard 31 Mar '19

31 Mar '19

I'm a bit late but the Candidate Release 1 is tagged in git and I have pushed the signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ This seems to be working in my limited testing, the CI is mostly green https://ci.centos.org/view/libvirt/ except for a few side things, so with a bit of luck that will work well. I may push the RC2 saturday morning, and then if everything looks good we can have the release on Tuesday. In the meantime, give it a try, especially on different platforms or OSes, thanks, Daniel -- Daniel Veillard | Red Hat Developers Tools http://developer.redhat.com/ veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/
