[CentOS-virt] Xen DomU supoprt in RHEL 7 and the CentOS Plan

Just for clarification sake, Xen is now part of the Linux Foundation and XenServer itself is open source as well.

Pretty much all of the bits to generate the XenServer build and all development of the Citrix product are done on Github now.

I get the push to use KVM but given the amount of interest and use there was on CentOS 6 with Xen, I believe the effort will still be made to get it into CentOS 7, which is why it would be nice if it was upstream as well.

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

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.
