1. CentOS (and upstream) 6.[012] still use the ethX convention.  I
expect that to continue throughout the lifetime of the 6.[0-9] series,
as upstream aims for consistency throughout the lifetime of 6.
2. Yes - you can eliminate NetworkManager.  I'm writing this on a
CentOS 6.1 desktop that's also running KVM.  I don't run
NetworkManager on this, as I want a static IP address defined at boot
that does not have anything else trying to mess with the network
config.
3. I can't speak to Fedora 15 -> CentOS 6 KVM compatibility, but if
you're moving existing guests, I'd be surprised if things didn't work.
4. RAID 1 from CentOS 6.0 to 6.2?  Shouldn't be a problem.
5. Software RAID from Fedora 12 working in CentOS 6.0.  Problems?  Probably not.
6. Caveats?  Plenty.  CentOS 6 is based upon RHEL6, which is based on
Fedora 12/13.  So going from Fedora 15, you're going a little back in
time.  You'd have to look at the release notes from Fedora 13 and up
to see the differences, as well as the CentOS/RHEL 6 release notes to
get the major changes from way back.  Example: no systemd.  I don't
know much more, as I haven't used Fedora in years...

Hope that helps...
