I'm tired of shell-scripting to wait for completion of a block pull, when virsh can be taught to do the same. I couldn't quite reuse vshWatchJob, as this is not a case of a long-running command where a second thread must be used to probe job status (at least, not unless I make virsh start doing blocking waits for an event to fire), but it served as inspiration for my simpler single-threaded loop. There is up to a half-second delay between sending SIGINT and the job being aborted, but I didn't think it worth the complexity of a second thread and use of poll() just to minimize that delay. * tools/virsh.c (cmdBlockPull): Add new options to wait for completion. (blockJobImpl): Add argument. (cmdBlockJob): Adjust caller. * tools/virsh.pod (blockjob): Document new mode.
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.
