vSphere with Tanzu using Intel Arc GPU

by // 1 Comment

After successfully passing through the new Intel Arc 750/770 GPU to both a Linux and Windows VM running on ESXi, which also includes keyboard/mouse access and video output to an external monitor, I wanted to see if our vSphere with Tanzu solution could also take advantage of the new Intel Arc GPU?


The answer is absolutely YES! 😀

In vSphere 7.0 Update 3 MP01 and later, vSphere with Tanzu introduced the support for adding a Dynamic DirectPath I/O device to a VM that is provisioned using the VM Service Operator. Before we can take advantage of the new Dynamic DirectPath I/O feature, we first need to create a new custom VM Class definition that maps to our Intel Arc GPU.

Using Packer vsphere-iso provider with VMware Cloud on AWS

by // 1 Comment

I am a huge fan of HashiCorp Packer, which makes automating Virtual Machine images for vSphere including OVF, OVA and vSphere Content Library Templates extremely easy. Packer supports two vSphere Providers, the first being vmware-iso which requires SSH access to an ESXi host and the second called vsphere-iso which does not require ESXi access but instead connects to vCenter Server using the vSphere API, which is the preferred method for vSphere Automation.

I started working with Packer and the vmware-iso several years ago and because there is not 100% parity between the two vSphere providers, I have not really looked at the vsphere-iso provider or even attempted to transition over. I was recently working on some automation within my VMware Cloud on AWS(VMConAWS) SDDC and since this is a VMware managed service, customers do not have access to the underlying ESXi hosts nor SSH access. I thought this would be a good time to explore the vsphere-iso provider and see if I can make it work in a couple of different networking scenarios.

For customers that normally establish either a Direct Connect (DX) or VPN (Policy or Route-based) from their on-premises environment to their SDDC, there is nothing special that needs to be setup to use Packer. However, if you are like me who may not always have these types of connectivity setup or if you wish to use Packer directly over the internet to your SDDC, then some additional configurations will be needed.

UPDATE (04/12/22) - A floppy option can now be used with Photon OS to host the kickstart file, see this Github issue for an example.

Packer Connectivity Scenarios

In both scenarios below, DX/VPN is not configure or relied upon to the VMConAWS SDDC.

Packer reference for PhotonOS Arm NFS Virtual Appliance using OVF properties for ESXi-Arm

by // 5 Comments

In case the title was not descriptive enough, I was curious if I could build an Arm Virtual Appliance (OVA) using OVF properties that would allow for all sorts of interesting guest customizations which I have blogged about before here, here, here and here using x86 PhotonOS as a reference implementation. My idea for this actually pre-dated the release of the ESXi on Arm Fling, but it was only until recently with support for VMware Tools for Photon OS Arm, was I able to finally piece together this solution.

It was also neat to see that I could build an Arm OVA using x86 tooling (Packer and OVFTool) which ran on my desktop and you simply needed an ESXi-Arm host. This really goes to show the level of compatibility from a management and vSphere API point of view that an ESXi-Arm host behaves just like a standard x86 ESXi host!

To demonstrate a more interesting use case than just basic network customization for the ?first? Arm OVA, I thought it would be useful to setup a simple NFS appliance that would take input from the user such the size of the exported volume (default 60GB) and then the name of the mount point. Upon first boot up, there is a guest customization script that would read in the OVF properties and configure the networking, OS password and NFS server configuration which you can certainly use to host your Arm VMs.
