Re: [Libvir] RFC: PATCH 3/5: verbose job progress in virsh

This patch updates virsh to make use of any APIs with new *Job variants. This means the 'create', 'start', 'save', 'restore', 'dump', 'net-create' and 'net-start' methods all now take a '--verbose' option. If this option is given, it will invoke the *Job variant of the API and print out increment progress information. eg, As an example of a job which has a bounded time, $ ./virsh --connect test:///default save --verbose test foo save [===== 18% ] Duration: 9 s, ETA: 41 s error: Cancelled domain save operation eg, As an example which is unbounded $ ./virsh --connect test:///default save --verbose test foo save [ = ] Duration: 9 s error: Cancelled domain save operation In the latter case, the '=' will bounce back & forth while the job is running. Both cases illustrate how the 'Ctrl-C' / SIGINT handler is hooked up such that 'virJobCancel' is run. Pressing Ctrl-C twice in quick succession will still immediately exit the program - useful if cancellation fails for some reason.
