Public bug reported:
With Ubuntu 16.04, I get frequent kernel panic crashes in my Linux KVM
guest. After notifying the hosting company the machine was migrated to a
different physical host which didn't fix the problem. A complete
reinstall of Ubuntu 16.04 also didn't fix anything. Therefore, I suspect
some sort of bug in the kernel and not a hardware fault or a corrupted
install.
