In anticipation of next month's release of Fedora 17 we have created a limited set of images to help participate in the beta program and explore the new options and features. Currently there are desktop and CLI images for VMWare, KVM and Xen and a CLI XVA template for XCP/XenServer. These are all 64-bit versions.
Fedora 17 x86_64 (BETA)
WARNING: Some users will not be able to boot the xen and/or xva templates due to a bug in Fedora 17's glibc that appears to conflict with some CPUs when run under Xen PV. There are no known workarounds at this time.
UPDATE (2012-05-14): The latest glibc has been patched to fix the Xen domU issue mentioned above. The CLI Xen image and XVA template have been rebuilt. These will probably be the last builds prior to the production release on May 22nd (which may be delayed again by upstream).
