It initially run correctly. 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]

-v | --verbose Verbose messages.
-d | --daemon Run as a daemon & write PID file.

-f | --config <file> Configuration file.
| --version Display version information.
-p | --pid-file <file> Change name of PID file.
