On this particular one, I suspect this is related to the machine being and older AMD proc which does not have all the instructions that openvswitch components were compiled with.

I found this in syslog:

This is the proc. Yes, it is very old, but still very brave (4 Cores and 16 GB RAM). Is this a lost cause?
