Yes, it started .. the CentOS QA-Team entered the 5.2 QA era .. meaning that we have to test a bunch of existing features and newer ones included in 5.2. For example, in the upstream announce mail i saw that the newer libvirt has support remote connections. So i decided to give it a try just after i updated my CentOS 5.1 x86_64 dom0 to 5.2QA (and my domU i386 and x86_64) ... but when i tried to connect, i received a 'connection reset by peer' (i tested with only ssh and not tls/certs) ... so i decided to read a little bit on the website and found which parameters should have been configured in the /etc/libvirt/libvirtd.conf (full list available here) . The only 'problem' so far is that the /etc/libvirt/libvirtd.conf is not provided by libvirt itself and doesn't exist ! .. Strange because it's referenced in the /etc/sysconfig/libvirtd (that you have to modify too) file .. So it seems you have to create it yourself , and then i was able to connect remotely (i tested only with ssh .. and important : don't forget that you need ssh key-based auth for this ...)

More informations about the QA tests later (and by other people/QA testers too ... ;-) )
