Debian 8 KVM Guest - Loading initial ramdisk
Thanks to the link @Someone posted in the comments to the question, I was able to pull this content which fixed the issue for me:
on the boot screen (below) press the "e" key to edit the configuration.
You will be shown a screen like follows.
Scroll down using the keyboard down arrow. You want the line that says
linux
Add the text
console=ttyS0
after the wordquiet
and then presscntrl + x
to proceedNow as root, or using sudo, run the command
systemctl enable getty@ttyS0
in order to never have to go through all those steps again.
