Hi,
Now, there are the following problems in virt-manager.log.
- The content of virt-manager.log is overwritten at the start
time of virt-manager.
- The log size is keeps increasing infinitely, if it keeps
using virt-manager.
The attached patch adds to solve these problems.
It is change points as follows.
* File mode -- append
* Log size -- 1MB(1024*1024)
* Number of Rotations -- 5

Nobuhiro Itou.
