But at any rate, the official 0.9.4 will probably be released tomorrow with even more bug fixes above 0.9.4-rc2. > Yeah , I was referring to 0.9.4-rc2 :) I will install the official libvirt 0.9.4 tomorrow . > > I tried installing in my Centos 5.6 machine.

Are you sure you installed your self-built libvirt.so correctly? We take great pains to ensure that libvirt.so is backwards compatible (no symbols are ever removed). > 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.
