Re: [libvirt-users] no connection driver available for No connection for URI xen:///

Alex, I changed the symbolic link to "/usr/local/lib/libvirt.so.0.9.10". Here is the running script: [root@XenTester libvirt-0.9.10]# rm /usr/lib64/libvirt.so.0 rm: remove symbolic link `/usr/lib64/libvirt.so.0'? yes [root@XenTester libvirt-0.9.10]# ln -s /usr/local/lib/libvirt.so.0.9.10 /usr/lib64/libvirt.so.0

I run "strace -o strace.txt virt-install --connect=xen:/// -p" once again, and the following error came out: ERROR Error in network device parameters: Virtual network 'default' does not exist: this function is not supported by the connection driver: virNetworkLookupByName the strace.txt is attached.

Are there any other places I need to change in order to let the system know I am running libvirt.so.0.9.10?

I saw virt-install is opening /usr/lib64/libvirt.so.0 in strace.txt: open("/usr/lib64/libvirt.so.0", O_RDONLY) = 7 I want to confirm whether you're using compiling libvirt 0.9.10, ll /usr/lib64/libvirt.so.0 say what?
