[one-users] 回复： Problem with Openvswitch on OpenNebula3.8

Wed Oct 2 09:05:35 PDT 2013

Hi there,

You should create the second host on the frontend with something like the
following:

# onehost create second_host -i kvm -v kvm -n ovswitch

Have you done that already?

Then on the second machine you must have an OVS bridge created with the
name as specified in
the vnet you have inside OpenNebula.

Good Will,
