[Rdo-list] SR-IOV on openstack: no valid host is found

Tue Aug 25 11:02:13 UTC 2015

Hi,

Anyone interested, I got it working using this procedure:

http://docs-draft.openstack.org/85/213985/10/check/gate-openstack-manuals-tox-doc-publish-checkbuild/1381a5e//publish-docs/networking-guide/adv_config_sriov.html

I'm using *RDO/Juno Centos 7.1*

My conf:

*Controller/Network Node:*

*/etc/neutron/plugins/ml2/ml2_conf.ini*

type_drivers = vlan
tenant_network_types = vlan
mechanism_drivers =openvswitch,sriovnicswitch

[ml2_type_vlan]
network_vlan_ranges =int-vlan:1440:1449

[securitygroup]
enable_security_group = True
firewall_driver = neutron.agent.firewall.NoopFirewallDriver

*/etc/neutron/plugins/ml2/ml2_conf_sriov.ini*

[ml2_sriov]
supported_pci_vendor_devs = 14e4:16af
agent_required = True

[sriov_nic]
physical_device_mappings = int-vlan:p2p1

*/etc/nova/nova.conf*
[Default]
scheduler_default_filters=RetryFilter,AvailabilityZoneFilter,RamFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,ServerGroupAntiAffinityFilter,ServerGroupAffinityFilter,PciPassthroughFilter
scheduler_available_filters = nova.scheduler.filters.all_filters
scheduler_available_filters =
nova.scheduler.filters.pci_passthrough_filter.PciPassthroughFilter

*/usr/lib/systemd/system/neutron-server.service*

ExecStart=/usr/bin/neutron-server --config-file
/usr/share/neutron/neutron-dist.conf --config-file
/etc/neutron/neutron.conf --config-file /etc/neutron/plugin.ini
--config-file /etc/neutron/plugins/ml2/ml2_conf_sriov.ini --log-file
/var/log/neutron/server.log

*Compute Node:*

I had to install ml2 plugin and sr-iov agent. Note, in the compute node
using rdo packstack the ml2 plugin is not installed by default.

# yum install openstack-neutron-ml2 openstack-neutron-sriov-nic-agent

*/etc/neutron/plugins/ml2/ml2_conf.ini*

[securitygroup]
# Controls if neutron security group is enabled or not.
# It should be false when you use nova security group.
# enable_security_group = True
enable_security_group = True
firewall_driver = neutron.agent.firewall.NoopFirewallDriver

*/etc/neutron/plugins/ml2/ml2_conf_sriov.ini*
[securitygroup]
firewall_driver = neutron.agent.firewall.NoopFirewallDriver

[sriov_nic]
physical_device_mappings = int-vlan:p2p1

*/usr/lib/systemd/system/neutron-sriov-nic-agent.service*
ExecStart=/usr/bin/neutron-sriov-nic-agent --config-file
/usr/share/neutron/neutron-dist.conf --config-file
/etc/neutron/neutron.conf --config-file
/etc/neutron/plugins/ml2/ml2_conf_sriov.ini --log-file
/var/log/neutron/sriov-nic-agent.log

Regards,
Pedro Sousa
