Mon May 22 15:34:20 CEST 2006 Karel Zak <kzak@redhat.com>
* src/virsh.c: added UUID: to the dominfo command, vshPrint() refactoring,
added support for domain look up by UUID
* virsh.1: added information about UUID, fixed list of commands and
domains statuses
* src/libvirt.c include/libvirt.h.in src/libvirt_sym.version: added
virDomainGetUUIDString() and virDomainLookupByUUIDString()
Wed May 10 15:50:32 CEST 2006 Karel Zak <kzak@redhat.com>

.IX Header "DESCRIPTION"
The \fBvirsh\fR program is the main interface for managing virsh guest
domains. The program can be used to create, pause, and shutdown
domains. The program can be used to create, suspend, resume, save, and shutdown
domains. It can also be used to list current domains. Libvirt is a C toolkit to interract with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the \s-1GNU\s0 Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C \s-1API\s0 initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.
