[OE-core] qemu woes on recent Fedora 24 kernels

[Krisztian Litkey]

  Hi,

I thought I share this with others in case I'm not the only one who
have been struggling with this recently. I've been running lately into
really bad (and non-deterministic) clock skew issues, often triggering
oopses, when testing images with qemu on fedora 24. I'm not sure what
has changed in the fedora kernels that triggered this behavior, but
switching the clock source from TSC to HPET (by appending
clocksource=hpet to the kernel command line in the generated qemu
config file) did the trick for me and got rid of the problems.

  Cheers,
    kli
