Nothing to do

上面的好象有问题，可以试试下面的这个:

[root@ok ~]# yum install -y kvm kmod-kvm qemu-img libvirt python-virtinst virt-manager virt-viewer bridge-utils

也会有个包没装：

# yum install -y kvm kmod-kvm qemu-img libvirt python-virtinst virt-manager virt-viewer bridge-utils
Loaded plugins: fastestmirror, refresh-packagekit, security
Setting up Install Process

但yum search kmod:

kmod-kvm-debug.x86_64 : kvm kernel module(s)
kmod-oracleasm.x86_64 : oracleasm kernel module(s)
kmod-rtsx_pci.x86_64 : rtsx_pci kernel module(s)

后来再次装的时候问题解决！！

Unable to open a connection to the libvirt management daemon.

[root@bass ~]# service libvirtd status
