Distributed Switch to Standard Switch Migrations

I was looking for a way to migrate VMkernel adapters back from a VDS to a VSS. This was because I am testing various upcoming releases of vCenter Server 8.0 and vSphere with Tanzu. vSphere with Tanzu, if you do not use NSX-T, requires a distributed switch and distributed portgroups. After building out some test environments, I wanted to roll back a distributed switch (VDS) configuration to a standard vSwitch (VSS) configuration. The process seems to have changed a few times in the past, and I could not find anything that demonstrated how to do task on vSphere 7.0. Thus…

VIO limitations with VDS networking

Earlier this month, I shared a post about my experiences with deploying VIO, VMware integrated OpenStack. One of the issues I highlighted was the fact that when I tried to create a network, it failed with a very unhelpful error message. The reason the network creation failed was due to a limitation with using a distributed switch (VDS). Instead I had to create what was known as a “provider network”, which is a special step needed for VDS networking. I am in the midst of an OpenStack training, and I’m trying to relate what I am learning on the training…

Adventures in VIO, VMware Integrated Openstack

I’ll start this post by stating straight up that I am no OpenStack expert. Far from it. In fact, the only reason I started to play with VMware Integrated OpenStack (VIO) was to get up to speed for a forthcoming OpenStack class that I am taking in next week. What I’ve documented here is a bunch of issues I ran into during the VIO deployment process. Hopefully these will prove useful to some folks who are also new to OpenStack and plan on going through the same exercise. I’m not going to describe VIO in any detail, nor any of…
