Almost everything there looks weird ;-) ovs-vswitchd is obviously
trying to set the Ethernet address but initially device br0 doesn't
exist ("No such device or address") and later it can't be changed
("Operation not supported"). Something is wrong on your system but it's
not obvious what.
What does "ifconfig br0" report?
