Hello,
I'm trying OpenStack Icehouse ML2 w/ SR-IOV (VLAN) on CentOS7 and ConnectX-3 cards (40gE):
(1) Mellanox-Neutron-Icehouse-Redhat-Ethernet - OpenStack
(2) Nova-neutron-sriov - OpenStack
(3) Mellanox OFED Driver Installation and Configuration for SR-IOV
After setting SR-IOV w/ ConnectX-3 while following (3), I also verified that vlan is working among systems.
I installed OpenStack Icehouse using packstack on single node (all-in-one).
And then, I modified all the configurations for SR-IOV while following (1), except /etc/neutron/dhcp_agent.ini.
I fixed the interface_driver from BridgeInterfaceDriver to OVSInterfaceDriver in /etc/neutron/dhcp_agent.ini.
Even though VM can get the DHCP IP, host and VM can't ping each other.
