Optinal: Create nested LXD container

lxc launch ubuntu:18.04 ${CONTAINER_NAME} -p disk-zfs -p nic-dev-mgmt -c boot.autostart=true -c security.nesting=true -c security.privileged=true
lxc exec ${CONTAINER_NAME} -- apt update
lxc exec ${CONTAINER_NAME} -- apt dist-upgrade
lxc exec ${CONTAINER_NAME} -- apt purge -y lxd lxd-client snapd unattended-upgrades
lxc exec ${CONTAINER_NAME} -- apt autoremove
lxc file push /root/.ssh/authorized_keys ${CONTAINER_NAME}/root/.ssh/authorized_keys
lxc exec ${CONTAINER_NAME} -- bash -c "sed -i 's/eth0:/dev-mgmt:/g' /etc/netplan/50-cloud-init.yaml"
lxc exec ${CONTAINER_NAME} -- netplan apply
printf 'lxc.apparmor.profile = unconfined\nlxc.cgroup.devices.allow = a\ sys:rw\nlxc.cap.drop=' | lxc config set ${CONTAINER_NAME} raw.lxc -
lxc restart ${CONTAINER_NAME}

Install Docker inside LXD container

FIX: While synchronizing instance power states, found XX instances in the database and XX instances on the hypervisor

Check kibana logs for
"While synchronizing instance power states, found"

Check libvirt VMs vs. nova DB

# get shutoff VMs on compute node
VMS_COMPUTE=$(ssh ${COMPUTE_NODE} docker exec -i nova_libvirt virsh list --state-shutoff --uuid | sed '/^$/d' | sort)
# echo "${VMS_COMPUTE}"
# get shutoff VMs from nova DB
VMS_NOVA=$(ssh os-admin-dev "source /etc/kolla/; openstack server list --all --host ${COMPUTE_NODE} -c ID -f value --status SHUTOFF" | sort)
# echo "${VMS_NOVA}"
# diff shutoff VMs
comm -3 <(echo "${VMS_COMPUTE}") <(echo "${VMS_NOVA}")

Remove shutdown VM from libvirt

OpenVswitch: cleanup interfaces without tap device

Show bridges without tab device

brctl show | egrep "qvb|tap" | sed '$!N;/\n.*tap/d;P;D' | awk '{print substr($1,4,8)}'

Get interface details

# show port details
docker exec openvswitch_vswitchd ovsdb-client dump | grep ${TOKEN}
# get OVS port
docker exec openvswitch_vswitchd ovs-vsctl list-ports br-int | grep ${TOKEN}
# get OVS interface
docker exec openvswitch_vswitchd ovs-vsctl list-ifaces br-int | grep ${TOKEN}
# show host bridges
brctl show | grep ${TOKEN}
# show host interfaces
ip a | grep ${TOKEN}

Delete interface

OpenStack: project

Create project

openstack project create foo-project --domain bar
for ROLE in ${ROLES}; do
    openstack role add --user ${USER_ID} --project ${PROJECT_ID} ${ROLE}
openstack role assignment list --names --user ${USER_ID}

OpenStack: Horizon

List templates

docker exec -it horizon bash
ls -l /var/lib/kolla/venv/lib/python2.7/site-packages/openstack_dashboard/themes

Configure theme

    ('default', 'Default', 'themes/default'),
    ('foo_bar', 'Foo bar', 'themes/foo_bar')
    ('foo_bar', 'Foo bar', 'themes/foo_bar')
DEFAULT_THEME = 'foo_bar'
