libvirt users - Jan 2017 - Virsh Fail to Connect to Hypervisor

Hi,

I am upgrading libvirt from 1.2.9 to 2.0.0 and I have successfully make the
libvirtd running. However, virsh cannot connect to hypervisor with following
errors:

virsh # connect
error: failed to connect to the hypervisor

root@node-55:/usr/local# virsh -c 'qemu:///system' connect
error: failed to connect to the hypervisor
error: no connection driver available for qemu:///system

Can you give me some suggestion about where will be the problem. Thanks.

libvirtd is running:
root@node-55:/usr/lib/python2.7/dist-packages# ps aux | grep -i libvirtd
root     1246963  0.0  0.0 1245780 3428 ?        Ssl  06:04   0:00
/usr/sbin/libvirtd --config /etc/libvirt/libvirtd.conf -l

Either you didn't install the QEMU driver for libvirt, or the QEMU driver
failed to initialize during libvirtd startup. Check the libvirtd logs for
the latter case, and make sure libvirt-daemon-driver-qemu RPM is installed
for the former.

Daniel
