Suppose there are 3 or more clients of libvirt: 1)nova 2)bash virsh commands 3)user customized ELF 4)etc....
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.
