As more clients start to want to know this information, doing a PATH stat walk and malloc for every client adds up. We are only caching the location, not the capabilities, so even if qemu-img is updated in the meantime, it will still probably live in the same location. So there is no need to worry about clearing this particular cache. * src/qemu/qemu_conf.h (qemud_driver): Add member. * src/qemu/qemu_driver.c (qemudShutdown): Cleanup. (qemuFindQemuImgBinary): Add an argument, and cache result. (qemuDomainSnapshotForEachQcow2, qemuDomainSnapshotDiscard) (qemuDomainSnapshotCreateInactive, qemuDomainSnapshotRevertInactive) (qemuDomainSnapshotCreateXML, qemuDomainRevertToSnapshot): Update callers.
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.
