Hi all,

I've managed to get his working, except SR-IOV vms cannot reach OVS vms and vice-versa. I've disabled firewall in ml2_conf.ini, openswitch and sriov agent files with this conf:

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

Still doesn't work. Any idea why OVS based nic cannot ping SR-IOV nics?

Thanks,
Pedro Sousa

Hi all,

thank you for your replys, concerning the dhcp issue, as I said it works some times, I also see this with tcpdump:

1º Joe, how can I check that VF has the right VLAN Tag?

2º My understanding is that VLANS are correctly configured as it works fine with Openvswitch.

Alon, I have the VLANS configured like this:

Eth104/1/2    SERVER2_NIC5      connected trunk     full    10G     --
Eth104/1/6    SERVER1_NIC5      connected trunk     full    10G     --

vlan 3482       (untagged)
vlan 2402       (tagged)
vlan 3480        (tagged)
vlan 3481        (tagged)
vlan 3485        (tagged)
vlan 3486        (tagged)
vlan 3487        (tagged)
vlan 3488        (tagged)
vlan 3489        (tagged)
vlan 3490        (tagged)
vlan 3491        (tagged)
vlan 3492        (tagged)

Pedro Sousa

Hi,

 

Some update on this, although I can launch the VM and see the VF inside it, I have 2 problems

 

1º Sometimes I don't get ip from dhcp when I launch a new instance.

 

Does the VF have the right VLAN tag?

 

 

2º I cannot ping the other hosts inside the tenant network using sr-iov nics. If I use ovs nics it works. 

 

 

Are VLANs setup properly?

 

Joe

 

Anyone has experienced this issues?

 

Thanks,

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

 

 

Where did you supply the whitelist?

 

Also, after making the whitelist change did you check the nova-compute.log? It typically reports the PCI devices that can be used for instances. 

 

Joe

1. type_drivers = vxlan,vlan

2. mechanism_drivers =openvswitch,sriovnicswitch
