Greeting,
We are about to update the centos-release-xen package to point to a newer
version of Xen. That is 4.12 on CentOS 7 but only 4.10 on CentOS 6.
As a reminder, you can "pin" your installation to Xen 4.8 by installing
centos-release-xen-48 and then removing centos-release-xen.
Other available Xen version are:
centos-release-xen-48
centos-release-xen-410
centos-release-xen-412 (CentOS 7 only)
On CentOS 6, ocaml is too old to build some component of Xen 4.12. There
may be other issues.
(I'll wait at least two weeks before pushing from testing to the release
repo.)
Cheers,
--
