Heya,
The last time we incremented versions for libvirt and QEMU was during the "Stein" release[1]. For "Train" we didn't do any. Although we advertized NEXT_MIN_{LIBVIRT,QEMU} versions for "Train" release to be libvirt 4.0.0 and QEMU 2.11.0, but we actually didn't bump; we'll do that for "Ussuri".
But before we bump the versions for "Ussuri", we need to pick NEXT_MIN versions for the "V" release. Based on the updated the DistroSupportMatrix page[2], it looks we can pick the next libvirt and QEMU versions for "V" release to the following:
libvirt: 5.0.0 [GAed on: 15-Jan-2019] QEMU: 4.0.0 [GAed on: 24-Apr-2019]
I have the initial patch here[3] for comments.
Debian, Fedora, Ubuntu[4], CentOS, RHEL currently already ship the above versions (actually, higher than those). And it is reasonable to assume -- but let's confirm below -- that openSUSE, SLES, and Oracle Linux would also have the above versions available by "V" release time.
Action Items for Linux Distros ------------------------------
(a) Oracle Linux: Please update your libvirt/QEMU versions for Oracle Linux 8?
I couldn't find anything related to libvirt/QEMU here: https://yum.oracle.com/oracle-linux-8.html. (My educated guess is: the versions roughly match what's in CentOS/RHEL.)
(b) openSUSE and SLES: Same request as above.
Andreas Jaegaer said on #openstack-infra that the proposed versions for 'V' release should be fine for SLES. (And by extension open SUSE, I assume.)

Assuming Oracle Linux and SLES confirm, please let us know if there are any objections if we pick NEXT_MIN_* versions for the OpenStack "V" release to be libvirt: 5.0.0 and QEMU: 4.0.0.
Comments / alternative proposals welcome :-)
