Hi, I recompile the libvirt-0.9.0 with "./configure --prefix=/usr --libdir=/usr/lib64 --localstatedir=/var --sysconfdir=/etc " in both the dell optiplex 780 and Xeon(R) E5620,find that in the dell 780 shows: root@Optiplex-780:/home/qinguan# virsh error：unable to connect to '/usr/local/var/run/libvirt/libvirt-sock', libvirtd may need to be started: 没有那个文件或目录(no such file or directory ) error：连接到管理程序失败(failed to connect the monitor) root@Optiplex-780:/home/qinguan# /usr/local/sbin/libvirtd -d root@Optiplex-780:/home/qinguan# virsh Welcome to virsh, the virtualization interactive terminal.
