[Compass-ci] Re: [PATCH v1 compass-ci 2/4] providers/libvirt: customizing logger format

• self.formatter = proc do |severity, datetime, _, msg|

Does _ mean a meaningless var? If so, you can refer the follow to make it more code-friendly? log_formatter = proc do |severity, datetime, _progname, msg|

-------- Thanks Yu Chuan

•  "#{datetime}-#{severity}: #{msg}\n"
