I would like to activate a network interface in the configuration for a QEMU/KVM connection in the application “Virtual Machine Manager 0.9.5”. But I stumble on the following error message.

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 96, in cb_wrapper
    callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 117, in tmpcb
    callback(*args, **kwargs)

    if ret == -1: raise libvirtError ('virNetworkCreate() failed', net=self)
libvirtError: internal error: Child process (/usr/sbin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/default.conf) unexpected exit status 2: 
dnsmasq: failed to set SO_REUSE{ADDR|PORT} on DHCP socket: Protocol not available

I would appreciate your advices.

Are any more software updates needed that correspond to a bug report like “dnsmasq: failed to set SO_REUSE{ADDR|PORT} on DHCP socket: Protocol not available”](https://bugzilla.redhat.com/show_bug.cgi?id=977555)?
