Bug Description

During verification bug https://bugs.launchpad.net/mos/+bug/1643081 I see the situation, when vms are active, but not available

Steps:
1) Enable sr-iov on 2 interfaces on different numas
2) Deploy env
3) Creat direct port and boot vm
NET_ID_1=$(neutron net-list | grep net_EW_1 | awk '{print$2}')

neutron port-create $NET_ID_1 --binding:vnic-type direct --device_owner nova-compute --name sriov_1
port_id = $(neutron port-list | grep ‘sriov_1' | awk '{print$2}')
nova boot vm1 --flavor m1.small --image ubuntu_image --availability-zone nova:$NODE_1 --nic port-id=$port_id --key-nae vm_key

4)ping vm rom dhcp-interface
Expected results:
Vm is in active state and is pinging
Actual result:
vm is in Active state but isn't pinging

Env:
snap 822? 1 compute with sr-iovs on 1 nume, 1 compute with 2 sr-iovs on different numas

We don't have proper driver i40evf in our image. The problem is because of that

Hi Timur,

Kristina is right - she used ubuntu-trusty cloud image for testing, which lacks SR-IOV driver for XL710-based cards (i40evf). As far as I know she added the driver to the image and now test passed.

If customers have such problems, it is necessary to build image with this driver or make it using trusty image (create vm with trusty image, download and install i40evf driver, make snap from it and boot vm from this snap)

The driver can be added by installing linux-image-extra packet: sudo apt-get install linux-image-extra-$(uname -r)

For verification purposes, we should properly maintain test image (e.g. we'd rebuilt Cirros for 9.0 for SR-IOV verification purposes).

For production usage, it's not a known issue, but it's the way how things works. It should be on User guide.
