Looks like qemu-common requires ceph, ceph requires
google-perftools-libs, and google-perftools-libs requires libunwind.
According to what I have been able to find on the fedoraproject.org web
site, libunwind has not been implemented yet. Am I really the only one
having this problem?

I worked around it by installing the google-perftools-libs package with
"rpm --nodeps". This allows qemu to update and everything seems to work,
but obviously this could bite me in the ass at some point, and equally
obviously, I shouldn't have to do this.

I'd file a bug against google-perftools-libs for requiring a bogus
library, but this seems like a problem that others should have run in
to, and I am reluctant to file a bug that will turn out to be my own
screwup somehow.
