virsh: volume: Fix lookup of volumes to provide better error messages
If a user specifies the pool explicitly, we should make sure to point out that it's inactive instead of falling back to lookup by key/path and failing at the end. Also if the pool isn't found there's no use in continuing the lookup. This changes the error in case the user-selected pool is inactive from: $ virsh vol-upload --pool inactivepool --vol somevolname volcontents error: failed to get vol 'somevolname' error: Storage volume not found: no storage vol with matching path somevolname To a more descriptive: $ virsh vol-upload --pool inactivepool --vol somevolname volcontents error: pool 'inactivepool' is not active And in case a user specifies an invalid pool from: $ virsh vol-upload --pool invalidpool --vol somevolname volcontents error: failed to get pool 'invalidpool' error: failed to get vol 'somevolname', specifying --pool might help error: Storage volume not found: no storage vol with matching path somevolname To something less confusing: $ virsh vol-upload --pool invalidpool --vol somevolname volcontents error: failed to get pool 'invalidpool' error: Storage pool not found: no storage pool with matching name 'invalidpool'
LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.

Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
