Description Osier Yang 2011-06-01 04:18:46 UTC

Description of problem:
As $subject says, if you have lxc domain which is inactive, you will see error like following in libvirtd log.

12:01:57.644: error : lxcMonitorClient:949 : Failed to connect to client socket: No such file or directory
12:01:57.644: error : lxcMonitorClient:949 : Failed to connect to client socket: No such file or directory

The problem is caused by we load all the domain configs for lxc domains in one stage, and then trys to connect the all the domain's monitor, regardless of wether the domain is active or not.
