KVM Ubuntu 18 Drive Encryption

So I created a new KVM VM and installed Ubuntu 18 with encryption selected on a qcow2 storage. It only boots every other boot try. When it fails it just has a square block of noise in the middle of the console window, almost the size of the console window but there is a healthy border. I force power off and select run and it works every time on the second try. Any ideas why it fails every other time?

What software did you use to create a virtual machine in?

Virtual Machine Manager, version 2.1.0.

It appears that the video doesn’t initialize correctly. Is there a log that I could look at?
