<br />症状：libvir: Remote error : unable to connect to 'localhost': Connection refused<br />解决：vi /etc/sysconfig/libvirtd取消注释 LIBVIRTD_ARGS="--listen"service libvirtd restart后即可

<br />编译安装libvirt_0.8.4之后，运行virsh报错：error: unable to connect to '/usr/local/var/run/libvirt/libvirt-sock': Connection refusederror: failed to connect to the hypervisor<br />后来发现./configure的时候最后的summary显示driver xen是no于是怀疑是xen的版本不对，yum install xen*

<br /> 操作：命令行运行virt-clone<br /><br />报错信息：Traceback (most recent call last):<br />  File "/usr/bin/virt-clone", line 25, in ?<br />    import virtinst<br />  File "/usr/lib/python2.4/site-packages/virtinst/__init__.py", line 27, in ?<br />    impor
