When shrinking a volume by a certain size, instead of typing vol-resize volume 1G --delta --shrink we allow the convience of specifying a negative value: vol-resize volume -1G --delta --shrink getting the same results with one more character. A negative value only makes sense as a delta. Imply the --delta parameter if the value is negative. Still require --shrink, because the operation is potentially destructive.
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.
