virsh: improve memory unit parsing
The last vestige of the inaccurate 'kilobytes' when we meant 1024 is now gone. And virsh is now useful for setting memory in units other than KiB. * tools/virsh.c (cmdSetmem, cmdSetmaxmem): Use new helper routine, allow passing bogus arguments on to hypervisor to test driver sanity checking, and fix leak on parse error. (vshMemtuneGetSize): New helper. (cmdMemtune): Use it. * tools/virsh.pod (setmem, setmaxmem, memtune): Document this.
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.
