I've already done make uninstall && ./autogen.sh --system && make && make install. However, while starting libvirtd, there is still an error here: Sorry I forgot the command line I used to start the libvirt service, here it is: [root@XenTester su]# /etc/rc.d/init.d/libvirtd start Starting libvirtd daemon: libvirtd: /usr/lib64/libvirt.so.0: version `LIBVIRT_PRIVATE_0.9.4' not found (required by libvirtd) libvirtd: /usr/lib64/libvirt.so.0: version `LIBVIRT_PRIVATE_0.9.4' not found (required by /usr/lib64/libvirt-qemu.so.0) [FAILED] Does it mean I cannot remove all of the libvirt binary by only running "make uninstall"? Are there any other ways can be used to remove the libvirt environment completely?

I think current xen URI works well for you, and you may try virt-install --connect=xen:/// -p -d or virt-install -p -d to confirm this. The above error is another issues, you need to change others stuff, it's not enough to just link /usr/local/lib/libvirt.so.0.9.10 /usr/lib64/libvirt.so.0, please follow answer 1. > > Are there any other places I need to change in order to let > the system know I am running libvirt.so.0.9.10? > > > Thanks, > > On Thu, Mar 15, 2012 at 10:54 PM, Su Zhang > <westlifezs(a)gmail.com <mailto:westlifezs@gmail.com>> wrote: > > Here it is: > > # ll /usr/lib64/libvirt.so.0 > lrwxrwxrwx. 1 root root 16 Mar 12 21:19 > /usr/lib64/libvirt.so.0 -> libvirt.so.0.9.4 > > So you meant that I used a wrong libvirt.so?
