I am using xen-4.2.2 with CentOS-6.4 as well as Fedora-19. I want to enable nested intel-VT (nested hypervisor) support for the domU. I couldn't find any documentation on this, but the release note says 4.2.2 has this feature. Can someone help me on this?

    Hi, my understanding is that nested visualization does not need enabling: all you need to do is to create a HVM guest domain, and install Xen in that guest domain (or KVM for that matter). There are probably some restrictions in Xen 4.2 (and fewer in Xen 4.3). You may want to check http://www.slideshare.net/xen_com_mgr/nested-virtualization-update-from-intel
