Re: [Kimchi-devel] [PATCH] List as many pools' info as possible

If a pool happens to be busy at the time the pool.refresh() is called, then libvirt will throw an error: "internal error: pool 'default' has asynchronous jobs running." Currently, kimchi rasise an exception and no pools' storage volumes are listed. This patch returns a 0 for that particular pool, and allows the user to continue to request information for other pools. Without this patch, nothing is shown at all on the Storage tab if one pool is busy. In the future, we can check for VIR_ERR_RESOURCE_BUSY and come up with a plan that works with the UI to display "Busy" for a pool. But for now, this works around the issue.
