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:
[ 0.732045] ..TIMER: vector=0x30 apic1=0 pin1=2 apic2=-1 pin2=-1
[ 0.736045] ..MP-BIOS bug: 8254 timer not connected to IO-APIC

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