Yeah , I was referring to 0.9.4-rc2 :) I will install the official libvirt 0.9.4 tomorrow .

I think so, I installed libvirt 0.9.4-rc2 on Centos 6 and it worked fine. I tried installing in Centos 5.6 (It had libvirt already installed through yum) . I did yum remove libvirt. Then I did ./configure --prefix = / , make , make install , ldconfig. When I enter virsh after finishing these steps, I get that error. I am not sure whether I am committing a mistake in-between. Please correct me if I am wrong. Thank you.
