It's a dangerous upgrade for sure. Why can't 4.4 be LTS for C6? >> as it's the last build with XM.

They also gave instructions: ==================================================== from the wiki: Xen-4.4 and libxl Note: All versions of Xen before version 4.4 had xm and xend enabled by default. The xen-4.4.1 (and newer) rpms instead enable xl support and no longer use xend.

How long will they release patches to 4.4? It is already listed as unsupported, with 4.5 and 4.6 the only supported versions. They have been releasing 4.4 patches recently .. not sure how much longer that will happen. Once they stop putting out 4.4 patches for XSAs, then it becomes difficult as the things they release for 4.5/4.6 will not necessarily work on 4.4 or below. George, do you know?
