Suppose there are 3 or more clients of libvirt:

The env LIBVIRT_DEBUG and LIBVIRT_LOG_OUTPUTS affects all of these clients, thus, they
will all
accumulate the logs into *ONE* file set by LIBVIRT_LOG_OUTPUTS.
There is no attempt to make sure that separate clients logging to
the same file will atomically write log lines. You could get half
a line of text from one client, then half a line of text from a
second client, then the rest of the line from the first client
all mangled up. You simply shouldn't give each client process the
same logging output file.
