The qemu block info function relied on working with local storage. Break this assumption by adding support for remote volumes. Unfortunately we still need to take a hybrid approach as some of the operations require a filedescriptor. Previously you'd get: $ virsh domblkinfo gl vda error: cannot stat file '/img10': Bad file descriptor Now you get some stats: $ virsh domblkinfo gl vda Capacity: 10485760 Allocation: 197120 Physical: 197120 Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1110198
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.
