I used strategy: 0) Do freebsd-update -r 12.1-RELEASE upgrade / install followed by rebuild = of kernel with "dev netmap" disabled in GENERIC. The combination of slow update download (due to going from 11.2 -> 12.1) ne= ed to rebuild kernel and using postmaster to re-build ports meant the entire process took around 6 hours. This was for machine with: bind, mysql & apach= e. Which is about as complicated as my FreeBSD VMs get. My other FreeBSD machines are dedicated to running single application: bind, apache/php or postgresql. The only one which is likely to problematic is the postgresql machine, as I don't want database to be unvailable for a long ti= me waiting kernel to rebuild, so will handle this last. Agree it is nice to have LTS stability, but I ended up where I am am due to needed some new features / fixes in QEMU / KVM hosting and related utilitie= s. So looking forward to Ubuntu 20.04 which should be stable and meet my needs. For FreeBSD Releases & QEMU / KVM Testing: Having some repeatable test process in place to validate VirtIO against: 1 release back, current and 1 release forward to ensure that things keep work= ing correctly. I believe this and the networking QEMU / KVM thread has been very helpful in finding source of issues, fixes and work arounds. Thanks you.
