Version-Release number of selected component (if applicable):
vdsm-4.16.2-1.gite8cba75.fc20.x86_64

How reproducible:
Always after getting into this state.

Steps to Reproduce:
1. Install some vdsm version (probably master few weeks before the upgrade)
2. Upgrade Fedora 19 to Fedora 20 using fedup
3. yum remove vdsm\*
4. yum install vdsm
5. vdsm-configure --force
6. systemctl start vdsmd

Actual results:
vdsm will not start

Expected results:
vdsm starts
Comment 1 Nir Soffer 2014-09-14 21:03:28 UTC 
Workaround:

1. Find the rule:
[root@voodoo4 ~]# grep -rn 84f08077-76be-4961-9a08-0acb93a2c029 /etc
/etc/libvirt/nwfilter/vdsm-no-mac-spoofing.xml:9:  <uuid>84f08077-76be-4961-9a08-0acb93a2c029</uuid>

2. Remove it
systemctl stop libvirtd
rm /etc/libvirt/nwfilter/vdsm-no-mac-spoofing.xml

3. Start vdsmd

Lowering severity for easy workaround.
