Mirantis version 7.0
ovs version: 2.3.1-1~u14.04
Some more reading on this points to possible bugs in ovs versions and
advise to upgrade the same.
Eg: Redhat solution doc 2104871.
Can someone put some more light on this?
If needed, is there a way for me to upgrade the ovs packages and
dependencies alone, while leaving rest of the cluster intact? Any help on
this is highly appreciated.
