Or being more specific,

 

How can a add key/value pairs to a compute node??? 

So I can check the extra_specs data with the key/value paris of the compute
node?

 

Cheers Viktor

Just one more noob question.

 

Is it normal that If I  set a set key/value pair let's say
{"my_special_key":"my_special_value"} to an existing flavor, that the
scheduler failed to find a host for an instance of this flavor.

 

(I use devstack with folsom stable code)

 

Cheers Viktor

The simplest way would be to create key/value pairs for flavor types
(instance types). 

This information would be associated in a separate table in nova db
(instance_type_extra_specs) and would go along with the instance type. 

 

Once it is in the database, you can use this information to customize all
kinds of things like the nova scheduler, additional data that can be passed
to the instance at the time of the creation. This is the high level
overview. If you search the mailing list archives you will find some
additional discussion about this topic.

Hi guys,

 

can anyone tell me (with an example) how to use the extra_specs variable for
an instance_type??

 

Best Regards
