Good day again Jesse. I wanted to provide you and the group with an update on our issue. We tried several times to get a kdump out of the system but never were able to successfully get that to work. Based on that we decided to take a look at the newer versions of Open vSwitch as you had mentioned that those might improve the issue we were seeing. Following this guide ( https://github.com/mininet/mininet/wiki/Installing-new-version-of-Open-vSwitch) I initially downloaded and installed version 1.93 of Open vSwitch. I don't know what it fixed, but as soon as that version was loaded I was able to start instances without the network or the compute nodes crashing. I so still have other deployment issues, but at least the vSwitch issue seemed to be resolved.
Since 1.9.3 was working I decided to just go ahead and upgrade both of the nodes running Open vSwitch to 2.0.0 so that we are running with the latest and greatest edition on them. So far no additional crashes have occurred. As soon as time allows I will load the 1.9.0 edition on my home system and reproduce the original issue I saw and see if I can get a kdump from it, but for now the newer editions have solved my immediate issues. Thank you again for all of your time investigating and assisting me with these issues. It is appreciated. Have a great week!
