Re: [libvirt] [PATCH 6/6] virsh: Add build flags to pool-create[-as] and pool-start

https://bugzilla.redhat.com/show_bug.cgi?id=830056 Utilize recently added VIR_STORAGE_POOL_CREATE_WITH_BUILD* flags in order to pass the flags along to the virStoragePoolCreateXML and virStoragePoolCreate API's. This affects the 'virsh pool-create', 'virsh pool-create-as', and 'virsh pool-start' commands. While it could be argued that pool-start doesn't need the flags, they could prove useful for someone trying to do one command build --overwrite and start command processing or essentially starting with a clean slate.
