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 + It's impossible for everything to be true. +
