[one-users] problems with openvswitch after upgrading to 4.4

[Jaime Melis]

Hi guys,

I just spoke with Samuel on the IRC and he's going to try and manually
revert this patch:

http://dev.opennebula.org/issues/2318
(
https://github.com/OpenNebula/one/commit/a775bb295802bccfd53b44d1e874b9a135efc130
)

He'll reply with the results. Let's see if we can narrow it down.

cheers,
Jaime
