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

[Richard Chan]

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!
