There is API for build the pool. The C level API is virStoragePoolBuild.
I.e. For a persistent pool, there are generally 3 steps to get a new
pool started.

1) define
2) build
3) start

The Python API: virStoragePool.build

For a non-persistent pool, you might want to use 
virStoragePoolCreateXML, which will create the pool as trasicient,
and start it. Yeah, no build process.

I'm thinking it's desired to introduce a flag for virStoragePoolCreate
and virStoragePoolCreateXML, to allow to build the pool meanwhile.
e.g. "--build" for command "virsh pool-start".
