[libvirt] cann't connect kvm hypervisor
Hello, I'm new of Opennebula. I have installed KVM im my remote node. But when I want to check the KVM in the node, I can't connect to the hypervisor. -------------------------------------------------------------------- root@forest:/var/run/libvirt# virsh -c qemu:///localhost/system list Connecting to uri: qemu:///system error: failed to connect to the hypervisor -------------------------------------------------------------------- Can somebody tell me why virsh doesn't work? And how I can fix it? I think that it's maybe the problem of libvirt. Any helps would be very appreciated?

I had similar problems earlier. The only solution I found without rebooting the machine is to killall kvm on the node. I would also appreciate any suggestion to better handle this problem. Thanks.

Hi Tino
I have checked that libvirtd deaemon is running. I have also restarted libvirtd deaemon, but I can't still connect to kvm hypervisor. ----------------------------------------------------------- root@forest:/var/run/libvirt# /etc/init.d/libvirt-bin start * Starting libvirt management daemon libvirtd [ OK ] root@forest:/var/run/libvirt# virsh -c qemu:///system list
Connecting to uri: qemu:///system error: failed to connect to the hypervisor -------------------------------------------------------------
other ideas?
Thanks

Hi Zhentao,
Can you check that the libvirtd deaemon is running in the remote node?

Please don't top post. You have one slash too many or remove localhost eg virsh -c qemu:///system list
