Kernel panics in guests are unlikely to be Nova bugs. This is probably
an underlying kvm / libvirt issue.

** Changed in: nova
       Status: New => Incomplete

Title:
  Kernel panic when configuring APIC timers in an instance

Status in OpenStack-Gate:
  New

Bug description:
  I am not sure Nova is the best candidate for this, but reporting
  nevertheless. Feel free to move to another project that is a better
  fit.

  This happened in gate in Queens.

  In instance console log, we can see:
