[Users] oVirt and firewalld

Hi, I've just set up a new oVirt installation with two nodes. Both of the nodes have had 'firewalld' disabled. When I went to test VM migration, it failed, apparently due to this (from the vdsm log on the source node): error : virNetClientProgramDispatchError:174 : Error while building firewall: Some rules could not be created for interface vnet0: Failure to execute command '$EBT -t nat -N libvirt-J-vnet0' : 'DBusException org.freedesktop.DBus.Error.ServiceUnknown: The name org.fedoraproject.FirewallD1 was not provided by any .service filesCouldn't connect to FirewallD, it's probably not running.'. Is running firewalld a requirement for oVirt? Is it possible to avoid having oVirt attempt to manage my firewall rules? Thanks! -- Jonathan Daugherty Software Engineer Galois, Inc.
