https://bugzilla.redhat.com/show_bug.cgi?id=888426 The code for doing a block-copy was supposed to track the destination file in drive->mirror, but was set up to do all mallocs prior to starting the copy so that OOM wouldn't leave things partially started. However, the wrong variable was being written; later in the code we silently did 'disk->mirror = mirror' which was still NULL, and thus leaking memory and leaving libvirt to think that the mirror job was never started, which prevented a pivot operation after a copy. Problem introduced in commit 35c7701c6. * src/qemu/qemu_driver.c (qemuDomainBlockCopy): Initialize correct variable.
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.
