You can set the required value in dictionary key:value pair and try to get the dictionary key , if key not set then below logic will give the default value

dict.get(key, default)

From the logs , it appears that the nova scheduler is trying to find the host with sufficient resources to spin up the instance, but unable to find it. Can you check what is the scheduler filters you have set on nova.conf file for the parameter scheduler_default_filters, based on this param nova is scanning the compute host to spin up the vm , but unable to find it.

2019-12-27 10:25:56 -0500 answered a question Necessity of tacker

Openstack is just a VIM (Virtualized Infrastructure Manager) , a backend to spin up the vm (the function of NFV components on vm plane) , Refer ETSI NFV Architecture.

Tacker is a vnf manager and acts on operations on vnf plane.( such as start/stop/pause/modify vnf components.)

2019-12-24 03:20:32 -0500 answered a question How to improve keystone performance?

Just check expiration interval set on keystone.conf file

You can also set keystone to use different backend to store the tokens.

keystone.token.backends.memcache- Memcached storage backend

keystone.token.backends.kvs - Key Value storage backend

Check if the cpu virtualization support is enabled on BIOS.

You can also check if the cpu supports the virtualization linux command - egrep -c '(vmx|svm)' /proc/cpuinfo

If the output is 0 , that means the virtualization is not supported , 1 or greater than 1 means its good to go.

Hi Nehal,

You can use a cinder volume attached to the vnf vm and preserve the cinder volume on termination of vnf (Ensure the r/w activity carried by vnf to cinder is stopped before termination to ensure no cinder volume corruption ), As per the tacker project this is already a blueprint/spec for this as well, you can check it -

You can use std.ssh module to do remote ssh onto the vm and use cmd to call the python program.

ssh_to_machine_minion{{ num }}:
  action: std.ssh
    delay: 5
    count: 15
     cmd: "cd /home/stack  && python"
     host: <% $.ip_interface_list_minion{{num}} %>
     username:  <% $.username %>
     password: <% $.password %>

If you are able to access the vm console ( default via nova vnc ) , check if ssh services are running on the virtual machine locally , you can issue the command ssh localhost or telnet localhost 22 , if this is good then you need to perform network troubleshoot.
