[virt-tools-list] [virt-manager][PATCH] Fix progres bar output bug in virt-clone.



From: Leonardo Garcia <lagarcia br ibm com>

The loop in StorageVolume._progress_thread that updates the cloning progress
bar has a call to sleep in the beginning of the loop which causes issues with
the progress bar. An example output (shorten to use less columns) with the
problem:

[laggarcia fedora18 virt-manager]$ ./virt-clone --connect
qemu+ssh://root 192 168 122 1/system --original=Fedora18-test --auto-clone
root 192 168 122 1's password:
Allocating 'Fedora18-test-clone.img'                                  |  20 GB  00:00:56

Clone 'Fedora18-test-clone' created successfully.
[laggarcia fedora18 virt-manager]$ '    4% [===-     ] -300039887.4 B/s | 881 MB  --:--:-- ETA

As the StorageVolume._progress_thread sleeps for one second when the loop
starts, it might occur that, when the cloning procedure finishes, the loop is
still awaiting to update the progress bar, which will cause a bad progress bar
update.

This simple fix solves this issue.
