Re: [ovirt-users] supervdsmd IOError to /dev/stdout

Hi, Could this be the cause of the access issue (old system upgraded from 3.4 all the way to 4.1)? ## change in python class name?? [handler_logfile] -class=logUtils.UserGroupEnforcingHandler +class=vdsm.logUtils.UserGroupEnforcingHandler When I copied svdsm.logger.conf.rpmnew over svdsm.logger.conf, it could start up.

Thanks!
