<DIV>> probly you should try to erase the 0.6.3, then compile and install</DIV>
<DIV>> libvirt</DIV>
<DIV>> like:</DIV>
<DIV>> </DIV>
<DIV>> # ./configure --prefix=/usr --libdir=/usr/lib64</DIV>
<DIV>> # make</DIV>
<DIV>> # make install</DIV>
<DIV>> </DIV>
<DIV>> your test program has no problem on my box. the libvirt on my box also</DIV>
<DIV>> is</DIV>
<DIV>> 0.6.3.</DIV>
