Original GitHub issue: https://github.com/retspen/webvirtmgr/issues/59

On WebVirtMgr panel v2.0.0 created from a new git clone.

I get a 500 error if any storage pool is stopped when I try to create a new VM.

It might be useful to trap this error and handle it by either telling the user about the problem or by giving the option to start the pool directly from the error page.

Need only active storage pool for create VM.

Does that mean you need all the pools active to create VMs?
Or just the one you plan on using for storage?

Need at least one where the VM images will be saved. Got to storage page and click button: "Start" or create new storage pool.

When I have:
storage pool 'default' online (started)
storage pool 'ubuntu1304' offline (stopped)
storage pool 'storage' online (started)
I still get the error. I would expect based on what you have said that this is not what is meant to happen.
As far as I can see from the code all pools would need to be started for it to work and allow for a new VM.
How can a storage location be refreshed 'stg.refresh(0)' if it is not started?
