I've finally updated the patches necessary to get the OVS plugin working on XS/XCP: https://review.openstack.org/#/c/15022/ https://review.openstack.org/#/c/15023 There's also a corresponding devstack patch to ensure the dom0 rootwrap is properly configured: https://review.openstack.org/#/c/27982/ I've updated the config doc if anyone wants to test things out for real: http://wiki.openstack.org/QuantumDevstackOvsXcp Reviewer love appreciated - especially if you are a Xen specialist (I'm looking at you current and former Citrix employees!). It would be great to finally see this merged into master! Cheers, Maru
