Re: [libvirt] Drop support for old libvirt versions?

A while ago, we agreed to drop support for QEMU versions older than 0.12.0, with the rationale that we should focus on operating systems that are still supported by the respective vendors, eg. RHEL/CentOS 6, Ubuntu 12.04 and SLES 11. Recently, when discussing how to ensure a certain change will not break migration with libvirt <= 0.9.4, I started wondering whether we should apply the same rationale to libvirt versions as well. Here's a quick run down of relevant libvirt versions:   SLES 11        → ???   RHEL 6.0       → 0.8.1   Ubuntu 12.04   → 0.9.2   RHEL 6.8       → 0.10.2   Ubuntu 12.04.5 → 0.9.8   SLES 11 SP4    → 1.2.5
