We made some tests to know the limit of simultaneous established connections a VM can support and we met some pb with 1.11 release (crashes...). So we try the new release 2.0.0 [1] (on the advice of KVM list [2] ) which had the support for the multiple threads for ovs-vswitchd process. And now, we no longer have limitations from OVS. Ubuntu ppa packages OVS 1.11.0 and 2.0.0 are available here [3] thanks to Sahid.
