Hi Chris, thank you for your answer. That will be great! :) I decided that I will write this deamon with Ruby and with old ruby bindings at least, so this is good news for me :) My friend from suse (Michal Hrusecky) did two patches till now - one is for virNodeGetFreememory a the second implements virConnectGetLibVersion. He sent these patches to David Lutterkort, but without answer. Do you want them? Sorry for my EN :/
