Because libvirt, virt-manager, etc, are definitely shown as available packages. As far as limitations and performance go, unless you have applications which push the 4GB memory limit of PAE, you will be essentially the same in either case, but will have a harder time finding third party applications for 64 bit. I have a pair of systems, i7-950, 12GB RAM, 4x1TB RAID5, doing VM hosting. One is fc13 i686, one is fc13 x86_64. There is no obvious performance difference, the only benefit of x86_54 is that I can run a 64 bit guest for testing. So: don't expect a big performance gain from 64 bit, unless you run some huge app you would not be likely to see it. Don't expect stability problems, I'm not sure that has ever lived up to the hype, the base OS seems fine, and has since fc6, when I first tried 64 bit. DO expect more effort in finding 3rd party apps, and occasionally some stability problems in that area (the latest 64 bit version of vlc locks up in 64 bit, for example). Don't expect to see a big difference whichever way you go, it depends on your desire for 3rd party apps to some extent. -- Bill Davidsen <davidsen@xxxxxxx> "We have more to fear from the bungling of the incompetent than from the machinations of the wicked." - from Slashdot -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
