<BR>
<P><FONT SIZE=2>Hello,<BR>
I'm new of Opennebula. I have installed KVM im my remote node. But when I<BR>
want to check the KVM in the node, I can't connect to the hypervisor.<BR>
<BR>
--------------------------------------------------------------------<BR>
root@forest:/var/run/libvirt# virsh -c qemu:///localhost/system list<BR>
Connecting to uri: qemu:///system<BR>
error: failed to connect to the hypervisor<BR>
--------------------------------------------------------------------<BR>
<BR>
Can somebody tell me why virsh doesn't work? And how I can fix it?<BR>
<BR>
Any helps would be very appreciated?<BR>
<BR>
Thanks<BR>
<BR>
Zhentao<BR>
