The biggest piece of advice I can give would be to move to EL6 (either RHEL 6 proper or CentOS 6). They will be supported for about six more years and their packages and patches go through much more rigorous testing, making it a much more ideal server platform. EL6 is (very loosely) based on Fedora 12, so the migration should be more or less painless for you, but of course, test on other machines. As for KVM (+qemu), it is a great hypervisor. The libvirtd tools are not always the most reliable under Fedora, so I don't rely on them (though I do use them). I don't know if you can simply dd out the VMWare storage for each VM and write it to the backing device or file and have it "just work", but on a test system, it should work. No matter what you do, mock it up on non-critical systems and dry-run it however many times is needed to get it right. You're talking about very fundamental and simultaneous changes... This will take time to get right. -- Digimer E-Mail: digi...@alteeve.com Freenode handle: digimer Papers and Projects: http://alteeve.com Node Assassin: http://nodeassassin.org "omg my singularity battery is dead again. stupid hawking radiation." - epitron -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
