Open Stack

Can a stock kernel with all the probing still intact ever perform as well as a custom one with all the non relevant stuff stripped out? Subsecond pod starting is very handy.

Thanks,
Kevin

Lokesh is working on Fedora RPMs.  I will leave the questions to Lokesh,
except to say that reusing kernel and QEMU packages is attractive
because it means fewer builds, fewer packages, and a smaller test
matrix.
