RHEL7 (rc) seems to be based on 3.10.x aswell: http://ftp.redhat.com/redhat/rhel/rc/7/Server/x86_64/os/Packages/ > The initial target for the Virt SIG will be to update the packages > inherited from xen4centos to Xen 4.4 and libvirt 1.2.2. > RHEL7 (rc) is based on libvirt-1.1.1. It would be nice to share the same base version as el7 does, but I guess the recent libvirt/Xen/libxl work by Jim is only in libvirt 1.2.x ? > We're currently in the process of brainstorming a "backlog" of work > items that might be a good idea.
