Re: [libvirt] [PATCH 0/7] vbox: drop support for many old versions

Per this link: https://www.virtualbox.org/wiki/Download_Old_Builds VirtualBox 6.0 (active maintenance) VirtualBox 5.2 (active maintenance) VirtualBox 5.1 (no longer supported, support ended 2018/04) VirtualBox 5.0 (no longer supported, support ended 2017/05) VirtualBox 4.3 (no longer supported, support ended 2015/12) VirtualBox 4.2 (no longer supported, support ended 2015/12) VirtualBox 4.1 (no longer supported, support ended 2015/12) VirtualBox 4.0 (no longer supported, support ended 2015/12) We can certainly drop all the 4.x versions. The host OS those are officially supported on are very outdated: eg https://www.virtualbox.org/wiki/Download_Old_Builds_4_3 Linux Hosts: Ubuntu 13.04 ("Raring") / 13.10 ("Saucy") / 14.04 ("Trusty") / 14.10 ("Utopic") i386 | AMD64 Ubuntu 12.10 ("Quantal") i386 | AMD64 Ubuntu 12.04 ("Precise") i386 | AMD64 Ubuntu 10.04 LTS ("Lucid") i386 | AMD64 Debian 7 ("Wheezy") i386 | AMD64 Debian 6 ("Squeeze") i386 | AMD64 openSUSE 12.3 / 13.1 i386 | AMD64 openSUSE 11.4 / 12.1 / 12.2 i386 | AMD64 SUSE Linux Enterprise Server 11 (SLES11) i386 | AMD64 SUSE Linux Enterprise Server 10 (SLES10) i386 | AMD64 Fedora 18 ("Spherical Cow") / Fedora 19 ("Schrödingers Cat") i386 | AMD64 Fedora 17 ("Beefy Miracle") i386 | AMD64 Mandriva 2011.0 i386 | AMD64 Oracle Linux 6 ("OL6") / Red Hat Enterprise Linux 6 ("RHEL6") / CentOS 6 i386 | AMD64 Oracle Linux 5 ("OL5") / Red Hat Enterprise Linux 5 ("RHEL5") / CentOS 5 i386 | AMD64 All distributions i386 | AMD64 Although the catch all "All distributions" suggest it might work with newer distros, they are clearly a second tier from a support POV. All these explicitly targetted distros are outside libvirt's support policy. There is a question as to whether to delete 5.0 and 5.1 support from libvirt. There are no remainining #ifdef VBOX_API_VERSION conditionals in the vbox_tmpl.h file related to code differences between 5.0, 5.1 and 5.2, so keeping them is not a maint burden in code. The main burden is distributing the large vbox_CAPI_v5_0.h and vbox_CAPI_v5_1.h files which are ~1 MB in size (uncompressed) or ~85 kb (xz compressed). IOW versions 5.0 and 5.1 increase the release tarballs by a small amount, but nothing that is too unreasonable vs the overall size of 14 MB for libvirt source. Thus I have kept 5.0 and 5.1 support. VirtualBox 6.0 came out in Dec 2018 and given past practice it would not suprise me if that has API changes impacting libvirt. So some interested party might want to look at supporting that in libvirt. Daniel P.
