This patch makes use of the newly added api virConnectListAllDomains() to list domains in virsh. Virsh now represents lists of domains using an internal structure vshDomainList. This structure contains the virDomainPtr list as provided by virConnectListAllDomains() and the count of domains in the list. For backwards compatibility, the function vshDomainListCollect was added that tries to enumerate the domains using the new API and if the API is not supported falls back to the older approach with the two list functions. The helper function also simulates filtering by all currently supported flags added with virConnectListAllDomains(). This patch also cleans up the "list" command handler to use the new helpers and adds new command line flags to make use of filtering.
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.
