The VMs in Launchpad's build farm have been on Ubuntu 16.04 (xenial) for some time. We're intentionally fairly conservative about upgrading the base VMs, but it's about time to have something newer, so we've just upgraded them to Ubuntu 18.04 (bionic). The actual builds still run in chroots or LXD containers of the appropriate Ubuntu series just as before, so most builds shouldn't notice any difference, but the kernel version is now 4.15 rather than 4.4. (As I type this, some VMs are still on xenial, but they'll be replaced with bionic once they're reset at the end of their next build.)
The powerpc (as opposed to ppc64el) VMs are an exception to this: bionic doesn't include the powerpc architecture any more, so these will stay on xenial until such time as we no longer need to dispatch any powerpc builds and can decommission those builders entirely.
