openstack platform is created on one server, using a KVM virtual machine. 7 virtual machine, a provisioning node, the control node 3 sets, three computing nodes. After creating an instance of the deployment is complete, I log on to see examples of them have not acquired IP address, we found no response is received. Well, I'll see if the network has no problem. I looked at each segment of each server NICs are through, no problem problem. Then I look at the situation ovs found a dpdk0 there is error, as follows:
Bridge-first-br
fail_mode: secure
Port "dpdk0"
Interface "dpdk0"
type: dpdk
options: {dpdk-devargs="0000:00:06.0", n_rxq="2"}
error: "Error attaching device '0000:00:06.0' to DPDK"
Br-Port first
Interface br-prv
type: internal
Port phy-br-prv
Interface phy-br-prv
type: patch
options: {peer=int-br-prv}
Then open the log file /var/log/openvswitch/ovs-vswitchd.log, found this error, Driver CAN not The attach at The Device (0000: 00: 06.0) know may be a problem with the network card driver does not support DPDK.
Behind the driver card have changed virtio re-deploy platform to create a virtual machine, the back just fine.
