Re: [libvirt] [PATCH 1/3] hw/i386: Remove the deprecated machines 0.12 up to 0.15

They can't be used reliable for live-migration anymore (see https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg04516.html

for details) and have been marked as deprecated since QEMU v4.0, so time to remove them now. And while we're at it, mark the remaining pc-1.x machine types as deprecated now, too, so that we finally only have "pc-i440fx" and "pc-q35" machine types left (apart from the non-versioned "isapc" and "microvm") once we removed them in a couple of releases.
