the error "Failed to access perfctr msr "
is a kernel error
and as is a bit normal for fedora it is using a very very new and not well tested kernel
( basically the users ARE the testers)
this error is showing up in the NEW 3.6 kernel
and if i had to guess
Parallels Desktop 7 hosted on an Mac OS X
being in a VM on a mac is the problem
and i DO NOT know of a fix other than rebuilding a kernel with a patch added ( maybe - I am skimming massage broads for postings)
I don't really want to hack software or tinker under the bonnet.
then i might offer installing a different Operating system
VM's are all fine and dandy BUT they do have limitations ( and advantages also )
My self i do not care for them much .
others LOVE THEM and could not even live without them
that is up to you
save any personal files then try OpenSUSE 12.2
it is NOT as "cutting / bleeding edge" as fedora
and has a longer lifespan than fedora
also it tends to be more stable
the target user IS NOT "the Tinkerer "
but " The Corporate OFFICE "
( well the not free version "SELD-suse enterprise linux desktop" is)
it is RPM based BUT suse dose things a bit differently - sometimes rather differently
and the wiki and docs
you sound like an engineer so
do a bit of research and before you know it
you will understand it - a lot better
