Robin VirtualBox OVS

I've been doing some work putting a Robin Systems deployment into CentOS7 VirtualBox VMs and I'm documenting that work here. Today I'm attaching the files that are used to create the OpenvSwitch ports to which the VirtualBox VMs attach via their ethernet adapters bridged to the OpenvSwitch ports. The Robin VirtualBox deployment has the VM's themselves on an OpenvSwitch. During the install, Robin itself installs another OpenvSwitch inside the VM's as part of the Robin product deployment.

The files attached all exist on the CentOS7 host (not in the VMs).

Also attached is the /etc/dhcp/dhclient.conf file which manages customized settings for "search" and "nameserver" for /etc/resolv.conf file.

I built the Robin on VirtualBox system successfully and then I ran a test on some NVME storage being presented to the VMs via the virtualized SATA controller (thus slowing down the NVME very signficantly). Here is a Linux FIO result set for the NVME device presented to the VirtualBox Robin node.

[root@centos-72a ezfio-master]# ./ezfio.py -d /dev/sdc -u 1

Install sdparm to allow model/serial extraction. Continuing.
