I can install a VM via this interactive installation mode once. However, it encountered another error while I was going to install with the same command another time. It seems that the sockets path has been changed. I checked that the default socket path is: /usr/local/var/run/libvirt/libvirt-sock, but it seems that the service is looking for a socket located at '/var/run/libvirt/libvirt-sock' (see 'ERROR Failed to connect socket to '/var/run/libvirt/libvirt-sock': No such file or directory' in the following running script) . I searched at livirtd.conf file but cannot find a place to reset this socket path. Could you let me know how to get around this issue? Here is the running script: [root@XenTester libvirt-0.9.10]# libvirtd --help Usage: libvirtd [options] Options: -v | --verbose Verbose messages. -d | --daemon Run as a daemon & write PID file. -l | --listen Listen for TCP/IP connections. -t | --timeout <secs> Exit after timeout period. -f | --config <file> Configuration file. | --version Display version information. -p | --pid-file <file> Change name of PID file. libvirt management daemon: Default paths: Configuration file (unless overridden by -f): /usr/local/etc/libvirt/libvirtd.conf Sockets: /usr/local/var/run/libvirt/libvirt-sock /usr/local/var/run/libvirt/libvirt-sock-ro TLS: CA certificate: /usr/local/etc/pki/CA/caert.pem Server certificate: /usr/local/etc/pki/libvirt/servercert.pem Server private key: /usr/local/etc/pki/libvirt/private/serverkey.pem PID file (unless overridden by -p): /usr/local/var/run/libvirtd.pid [root@XenTester libvirt-0.9.10]# virt-install --prompt ERROR Failed to connect socket to '/var/run/libvirt/libvirt-sock': No such file or directory Thanks, > > > > > > > > > > > > Thanks, > > > > > > > > > > > > > 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. > 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 > > 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?
