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

[שחם פרידנברג]

Hey all,

I deployed openstack on DELL PowerEdge R620 installed with Centos 7.

SR-IOV is enabled in BIOS (both Virtualization Technology & SR-IOV).

Also, I added the needed kernel parameters and created virtual functions on
82599 Intel 10G NIC.

in nova.conf:

1.
pci_passthrough_whitelist={"devname":"p2p1","physical_network":"sriovnet"}
2.
scheduler_default_filters=RetryFilter,AvailabilityZoneFilter,RamFilter,ComputeFilter,ComputeCapabilitiesFilter,
  ImagePropertiesFilter,CoreFilter,PciPassthroughFilter

in ml2_conf.ini:

1. type_drivers = vxlan,vlan
2. mechanism_drivers =openvswitch,sriovnicswitch
3. network_vlan_ranges = sriovnet:80:90
in ml2_conf_sriov.ini:

1. supported_pci_vendor_devs = 8086:10ed
2. agent_required = False
in neutron-server.service:

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

created Network based on physical network I defined (sriovnet), configured
subnet and created direct type port.

When I creating an image (nova boot --flavor m1.large --image my_img --nic
port-id=087ff574-fb14-47fd-82cb-454f176154ff test_sriov)

I get the following error:

Any idea what might be the problem here?

Thanks,
