The install fails because the boot kernel throws some oopses and reboots the server in an endless loop. The system powers on. Petitboot loads and populates the boot options. The system PXE boots the ephemeral boot kernel and then OOPSes and reboots, starting the cycle over. The following is the most I could get from a SOL session but it does show where the panics begin and the reboot happens at the end. The dump is from an attempt via MAAS to deploy Xenial with the 4.15 edge kernel. I also tried Bionic using the default kernel and got the same issue. Next I tried Xenial with the 4.13 kernel (hwe-16.04) and that kernel successfully boots. So the issue seems localized to the 4.15 kernel.
