Fedora 19 recently went beta with a projected final release date in early July. Beta Xfce Desktop and CLI images for VMWare, KVM, Xen, XCP/XenServer and SolusVM Xen are ready for download. These are all 64-bit versions. 32-bit templates will be added upon the upstream production release.
The NetBSD lightweight xen templates have been upgraded to version 6.1, which was released by the NetBSD project last week. For those still running the 5 series of releases, the images have been re-revved to 5.2. These are extremely small images that require the appropriate NetBSD domU kernel as noted on each respective download page.
The second (and final) beta release of Ubuntu is available. Lightweight and desktop templates have been published for SolusVM Xen PV, VMWare, KVM, XCP/XenServer and Xen. The 64-bit builds are actually BETA 1 and the 32-bit builds are BETA 2. Final builds are expected in late April per the above schedule
