Re: [Kimchi-devel] [PATCH] issue #312: Check volume group exists while creating a logical pool

From: Aline Manera <alinefm(a)br.ibm.com&gt; When creating a logical storage pool, a volume group is created with the same name. And when deleting the storage pool the volume group keeps on the system. Which is the correct behavior as the storage pool is only a concept and deleting it should not affect the file system. To avoid problems while creating a pool with an existent volume group name, verify if a volume group exists with the given pool name and if so, warn the user about it. Also convert an error message parameter to string instead of virStoragePool instance and update the po files as new messages were added.
