I did not have a console attached when it rebooted, so I did not have a log of
the initial boot. Now that I did, I see that it fails to mount its root volume.
It had been running previously on pvhvm_v10 for about two weeks without
problems. I updated my local git, and recompiled the kernel and rebooted. Then
this happened.
In order:
Booting...
