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

COMPUTE_NODE=com1-dev
 
# 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/admin-openrc.sh; 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

TOKEN=cac559da
 
# 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
