There are no tools either. Last time I checked, Xen support wasn't evenincluded with libvirt on RHEL7rc. :/ Given Red Hat's focus on and direct freeware support of KVM, why should they burn cycles on open source integration of a product that has a closed source upstream vendor at Citrix? They'd be much better off spending the engineering time on libvirt and getting the NetworkManager configuration tools to correctly support KVM compatible bridging or ordinary network pair bonding, jumbo frames, and VLAN tagging. None of that was working correctly on CentOS 6 or RHEL 6 without hand editing config files, which would be overwritten and scrambled by using NetworkManager to configure anything. I've not spent time with the latest NetworkManager on the RHEL 7 betas, and would be very curious to see if they've gotten *that* straightened out. In Red Hat's position, I'd contact Citrix and get *them* to do the testing and debugging, which they'll need to do for their commercial products, anyway. That might get into interesting open source licensing issues, but it's a lot cheaper than replicating testing labs and doing Citrix's work for them.
