[libvirt-users] Unable to connect qemu:///system on CentOS 6.2 X86_64

[suyi wang]

Dear all:
    I ust installed Fedora16Fedora16 X86_64 on my new machine, and then I
ran the commands as follows(ran as root):

yum install qemu-kvm
yum install qemu
yum install libvirt
yum install virt-manager

   then I started the libvirtd as follow:
/etc/init.d/lbvirtd start

So , it ran well.


However, after a few days , when I ran the command "virt-manager" , it
showed as in the attachment.



it seemed that ti cannot connect the hipervisor.


Then I did a little test:
I ran the conmand "virsh list" , but it didnot work,either.

Then I used Python as follows:
import libvirt
cc = libvirt.open(r'qemu:///system'
)

but it didnot work,either.


All the test above are under root . I hope that someone can give me some
suggestiion. Thanks to all!
