Peter Krempa 641ed83e3d qemuDomainBlockResize: Properly resize disks with storage slice
Until now resizing a disk with a storage slice would break in one of the
following ways:

1) for a non-raw format, the virtual size would change, but the slice
would still remain in place
2) for raw disks qemu would refuse to change the size

The only reasonable scenario we want to support is a 'raw' image with 0
offset (inside a block device), where we can just drop the slice.

Anything else comes from a non-standard storage setup that we don't want
to touch.

To facilitate the resize, we first remove the 'size' parameter in qemu
thus dropping the slice and then instructing qemu to resize the disk.

Libvirt API for virtualization

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.

For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.

Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
