Description of problem:

Running virt-install from Chinese, Japanese or any other non english locale, ends up causing virt-install to fail prematurely.  It bails out due to a bad date format ( as far as I can tell) in the virt-manager, which is passed through to python logging framework.

Version-Release number of selected component (if applicable):

F10, F11, Rawhide, RHEL5.

How reproducible:

Every time.

Steps to Reproduce:
1. Become one with uid 0.
2. export LANG=zh_CN.UTF8
3.# virt-install 
Traceback (most recent call last):
  File "/usr/lib64/python2.6/logging/handlers.py", line 74, in emit
    if self.shouldRollover(record):
  File "/usr/lib64/python2.6/logging/handlers.py", line 145, in shouldRollover
    msg = "%s\n" % self.format(record)
  File "/usr/lib64/python2.6/logging/__init__.py", line 637, in format
    return fmt.format(record)
  File "/usr/lib64/python2.6/logging/__init__.py", line 428, in format
    s = self._fmt % record.__dict__
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe4 in position 1: ordinal not in range(128)
ERROR    虚拟机需要一个名称。   

I assume the above message says like its english counterpart which is something along the lines of name not specified.
  
Actual results:

Application throws python traceback exception.

Expected results:

Application to not throw an error.

Additional info:

I will attach a patch which attempts to fix the problem, the only downside that I could notice is that the date stamps in the log file$HOME/.virtinstall/virt-install.log were no longer in the native locale.  Error messages remained the same.
