使用vmware虚拟机安装virt-manager unable to connect to libvirt的处理办法

hk8lo

  RHEL7.0在安装完成virt-manager后，启动libvirtd服务进程

1 2	[iyunv@demo Desktop]# systemctl enable libvirtd [iyunv@demo Desktop]# systemctl start libvirtd

在使用virt-manager命令启动虚拟机管理软件时，提示unable to connect to libvirt

1 2 3 4 5 6 7 8 9 10 11 12 13 14

Unable to connect to libvirt. no connection driver available for qemu:///system Libvirt URI is: qemu:///system Traceback (most recent call last):   File "/usr/share/virt-manager/virtManager/connection.py", line 969, in _open_thread     self._backend.open(self._do_creds_password)   File "/usr/share/virt-manager/virtinst/connection.py", line 157, in open     open_flags)   File "/usr/lib64/python2.7/site-packages/libvirt.py", line 105, in openAuth     if ret is None:raise libvirtError('virConnectOpenAuth() failed') libvirtError: no connection driver available for qemu:///system

此时可能是驱动程序的安装有问题，更新device-mapper包

1	[iyunv@demo Desktop]# yum update device-mapper

此时libvirtd服务显示为正常，没有出现报错，再次运行virt-manager，可以正常连接
