A generic error code was returned, if the user aborted a migration job. This made it hard to distinguish between a user requested abort and an error that might have occured. This patch introduces a new error code, which is returned in the specific case of a user abort, while leaving all other failures with their existing code. This makes it easier to distinguish between failure while mirgrating and an user requested abort. * include/libvirt/virterror.h: - add new error code * src/util/virterror.c: - add message for the new error code * src/qemu/qemu_migration.h: - Emit operation aborted error instead of operation failed, on migration abort
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.
