I put the things I know about in the 4.5 vote thread, to hopefully make it into release notes or something later on. I haven't followed up to see if that has happened.
The primary things that come to mind for 4.5 are the interface device names and a cgroups issue. For networking, we only support eth*,bond*,vx*,em*,vlan*, and even then only support physical device names with up to 8 characters, It may be tough to support some custom/dynamic nic names, but we could also add eno* to the list for better support. In the meantime this can be worked around with some kernel params (biosdevname=0 net.ifnames=0) that go back to the standard "eth" naming. The cgroups issue is that by default now the cpu and cpuacct cgroups are 'comounted', so libvirt throws up when we try to use them. You can see this in /sys/fs/cgroup, cpu and cpuacct share a mount "cpu,cupacct" rather than having their own. Specify an empty JoinControllers parameter in /etc/systemd/system.conf to fix this. Other than that, the iptables command compatibility layer seems to keep things working from a security groups perspective, and the libvirt/qemu versions seem to be compatible.
