[PATCH] Redirect stdout & stderr when run as out-of-process provider

However, when loaded out-of-process, those same messages appear on the console. This happens excessively when libvirt-cim LXC_ and XEN_ classes are enumerated and libvirt sends "libvir: error : no connection driver available for..." messages to stderr. In development, this can sometimes prevent console usage. Until a fix is made to Pegasus, we'll suppress console output during provider initialization when run in out-of-process mode.

libvirt-cim migrating to git
by Chip Vincent 22 Sep '11

22 Sep '11

libvirt-cim community, We'll be migrating the libvirt-cim source tree from hg to git in the very near future. Once complete, we'll keep the hg tree up for a while, but updates will only be made to the git tree. The intention of this migration is simply to be more consistent with other projects many of us work on, which, of course, uses git. I'm in the process now of doing some test migrations locally to ensure the tools work properly. If everything goes well, I hope everything up and running on libvirt.org sometime next week. I'll send a note to the once the docs are updated and the git tree is accessible, and another down the road sunsetting the hg tree. -- Chip Vincent Open Virtualization IBM Linux Technology Center cvincent(a)linux.vnet.ibm.com

Better to Add Code to check "End of line" character in schema file
by Wayne Xia 15 Sep '11

15 Sep '11

When I try add new class to libvirt-cim, I found that if the "end of line" character use the windows format(\t\n), then the rpm making would succeed, but the pegasus would not find the correct .so file, indeed pegasus seems to linked to a wrong file. It takes me a long time to find the reason, so I think it is better to add some scripts to check this, or show a warning for it. -- Best Regards Wayne Xia mail:xiawenc@linux.vnet.ibm.com tel:86-010-82450803
