	I'm not convinced virsh needs this either:

   - What other similar shell logs its errors/debug to a file?

   - You generally want to see debug/error messages on stdout/stderr 
     when debugging something, rather than having to go poking in a 
     separate log file

     e.g. the log won't be much good if I'm doing:

       $> ssh markmc foo virsh --debug 6 list

   - Logging stuff to ~/.virsh is not something people will expect - 
     I'd imagine most people would be surprised to find a log file

   - Log rotation, log file size, remote logging, log filtering etc. 
     are all solved problems ... let's not try and re-solve them

Cheers,
Mark.
