Not OVS for sure!! I tried a control experiment: Debian 7.8, OVS 2.3.3
# cat /etc/debian_version 7.8 root@labeled3sb1:/home/data/pcap/20150626# ovs-vsctl --version ovs-vsctl (Open vSwitch) 2.3.3 Compiled Jun 26 2015 16:52:46 DB Schema 7.6.2 root@labeled3sb1:/home/data/pcap/20150626# uname -r 3.2.0-4-amd64 root@labeled3sb1:/home/data/pcap/20150626# ifconfig | grep MTU shows all 1500 No errors in dmesg at all. The VM behind the OVS is happy as a clam, no timeouts no need for MTU adjustments. Sorry for the trouble and thanks for all the help Jesse. Emil I think it may be prudent to reinstall on a 7.8 and not let apt-get upgrade or update get in the way and see.

Thanks! OK, thanks. I guess it seems somewhat unlikely to be related to OVS at this point, although I don't have a good theory as to what would cause this. Let us know if you find anything more. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
