I agree with the direction you mentioned.

On CentOS, libcacard is built as a separate RPM and installed to /usr/lib64,
which will conflict with our build with this patch.

But keep our libcacard under /usr/lib also seems wrong.

Could you please generate a patch to put libcacard etc staff into
$prefix/lib/xen and build qemu with rpath?

I'm not a expert on these staff but I can test it.

Thanks,

Zhigang
