In my personal environment, I've got 7 machines running, with 4 of those machines running various flavors of Linux (CentOS 5 x86_64; Fedora 15 x86_64; Fedora 14 i686). Based upon some issues with the Fedora 15 x86_64 machine I'm considering dropping Fedora 15 in favor of CentOS 6.1. My questions are: On the networking side, has a there been a move to change the ethernet names from eth0 to em1? After install, can I change from NetworkManager to plain network? On my CentOS 5 machine I'm running VMware Server 2 and would like to move to KVM virtualization on the Fedora 15/CentOS 6.1 box. Is the level of KVM comparable between Fedora 15 and CentOS 6? If I install CentOS 6.0 and sometime later upgrade to CentOS 6.2, will the fact that I'm running software raid-1 on the /boot partition cause me grief? Will the fact that I'm running software raid-1 and LVM that was defined under Fedora 12 cause me grief? Are there any caveats moving from Fedora 15 to CentOS 6?
Any advise?
Thanks, Gene Poole

6.2 is the kind of release that those in the community and TUV call a 'point release'. Reading the FAQ may help you. "14. What is the versioning/release scheme of CentOS and how does it compare to the upstream vendor?" http://wiki.centos.org/FAQ/General#head-6e2c3746ec45ac3142917466760321e8 68f43c0e
And I think the backport link to redhat in the following FAQ could be useful for you to understand. "20. Where can I get the latest version of XyZ.rpm for CentOS? I cannot find it anywhere." http://wiki.centos.org/FAQ/General#head-472ce8446ebcfc82ca1800f775ba0e62 9ac835c7

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...

You can use this packages: http://rpms.plnet.rs/plnet-centos6-i386/RPMS.centdos/gnome-netstatus-2.28.1-... and http://rpms.plnet.rs/plnet-centos6-x86_64/RPMS.centdos/gnome-netstatus-2.28....
to restore Gnome network applet functionality. I recompiled it from Fedora.
