I have just started using MAAS and testing on a KVM environment with isolated virtual network connected through NAT to the outside Internet.
MAAS installed fine in a KVM VM and I am able to commission and deploy Ubuntu servers in their own KVM VM’s through BIOS mode.
But when I try to commission a new VM in UEFI mode, it fails to boot. I get a good iPXE sequence but this error message and then it fails through to a shell. I’ve tested this on my Ubuntu 16.04 metal host and my own Mint 18.03 desktop KVM testing environment. Google Fu no help
