USB 3.0 Ethernet Adapter (NIC) driver for ESXi 6.5

11.17.2016 by William Lam // 189 Comments

I had several folks ask me about an updated USB 3.0 Ethernet Driver for ESXi 6.5, similar to what I had created for ESXi 5.5 and 6.0. There were some changes that came with ESXi 6.5 and thanks to Songtao, I was able to build a new driver. For those of you who are not familiar with this particular driver, I highly recommend you give this article here a read before proceeding any further. If you are interested in Realtek driver for ESXi 6.5, be sure to check out Jose's blog here for more info.

UPDATE (02/12/19) - A new VMware Native Driver for USB-based NICs has just been released for ESXi 6.5/6.7, please use this driver going forward. If you are still on ESXi 5.5/6.0, you can continue using the existing driver but please note there will be no additional development in the existing vmklinux-based driver.

UPDATE (04/23/18) - For folks who plan to upgrade or install ESXi 6.7, you can continue using the 6.5 driver. I've had several folks reach out and share there have not been any issues and upgrades will preserver the USB NIC driver or you can perform a fresh install and follow the steps below.

To use this new driver for ESXi 6.5, there are some additional steps that is required. Below are the instructions on how to install this on an ESXi 6.5 host.

Step 0 - Download the ESXi 6.5 USB Ethernet Adapter Driver VIB or ESXi 6.5 USB Ethernet Adapter Driver Offline Bundle and upload it to your ESXi host.

Step 1 - If you are upgrading from an existing ESXi 5.5 or 6.0 environment, the first thing you will want to do is uninstall the old driver by running the following command (specify the correct name of the driver):

esxcli software vib remove -n vghetto-ax88179-esxi60u2

Step 2 - Install the VIB by running the following ESXCLI command to install:

esxcli software vib install -v /vghetto-ax88179-esxi65.vib -f

Step 3 - Next, you will need to disable the USB native driver to be able to use this driver. To do so, run the following command:

esxcli system module set -m=vmkusb -e=FALSE

Step 4 - Lastly, for the changes to go into effect, you will need to reboot your ESXi host. Once your system has rebooted, it should now automatically load the USB Ethernet driver and you should see your USB Ethernet Adapter as shown in the screenshot below.

Step 5 - ESXi does not natively support USB NIC and upon a reboot, the USB NICs are not picked up until much later in the boot process which prevents them from being associated with VSS/VDS and their respective portgroups. To ensure things are connected properly after a reboot, you will need to add something like the following in /etc/rc.local.d/local.sh which re-links the USB NIC along with the individual portgroups as shown in the example below.

esxcfg-vswitch -L vusb0 vSwitch0
esxcfg-vswitch -M vusb0 -p "Management Network" vSwitch0
esxcfg-vswitch -M vusb0 -p "VM Network" vSwitch0

You will also need to run /sbin/auto-backup.sh to ensure the configuration changes are saved and then you can issue a reboot to verify that everything is working as expected.

How to deploy the vCenter Server Appliance (VCSA) 6.5 running on VMware Fusion & Workstation?

10.27.2016 by William Lam // 31 Comments

As with any new release of vSphere, it is quite common for customers to deploy the new software in either a vSphere home or test lab to get more familiar with it. Although not everyone has access to a vSphere lab environment, the next best thing is to leverage either VMware Fusion or Workstation. With the upcoming release of vSphere 6.5, this is no different. In fact, during the vSphere Beta program, this was something that was asked about by several customers and something I had helped document as the process has changed from previous releases of the VCSA.

In vSphere 6.5, the VCSA deployment has changed from a "Single" monolithic stage where a user enters all of their information up front and the installer goes and deploys the VCSA OVA and then applies the configurations. If you had fat finger say a DNS entry or wanted to change the IP Address before applying the actual application configurations, it would not be possible and you would have to re-deploy which was not an ideal user experience.

In vSphere 6.5, the new UI installer will still allow you to perform a "Single" monolithic stage but it is now broken down into two distinct stages as shown below with their respective screenshots:

Stage 1 - Initial OVA deployment which includes basic networking

vcsa-6-5-installer-1
Stage 2 - Applying VCSA specific personality configuration

vcsa-6-5-installer-2
Just like in prior releases of the VCSA, the UI translates the user input into specific OVF properties which are then passed into the VCSA guest for configuration. This means that if you wish to deploy VCSA 6.5 running Fusion or Workstation, you will have two options to select from. You either deploy VCSA and complete both Stage 1 and 2 or just Stage 1 only. If you select the latter option, to complete the actual deployment, you will need to open a web browser to the VAMI UI (https://[VCSA-IP]:5480) and finish configuring the VCSA using the "Setup vCenter Server Appliance" option as shown in the screenshot below.

vcsa-6-5-installer-3
If your goal is to quickly get the VCSA 6.5 up and running, then going with Option 1 (Stage 1 & 2 Config) is the way to go. If your goal is to learn about the new VCSA UI Installer, then you can at least get a taste of that by going with Option 2 (Stage 1 Config) and this way you can step through Stage 2 using the native UI installer.

One last thing I would like to mention is that there have been a number of new services added to the VCSA 6.5. One example is that vSphere Update Manager (VUM) is now embedded in the VCSA and it is also enabled by default. With these new services, the tiniest deployment size is going to require 10GB of memory where as before it was 8GB. This is something to be aware of and ensure that you have adequate resources before attempting to deploy the VCSA or else you may see some unexpected failures while the system is being configured.

Note: If you have access to fast SSDs and would like to overcommit memory in Fusion or Workstation, you might be able to get this to work leveraging some tricks mentioned here. This is not something I have personally tested, so YMMV.

Here are the steps to deploy VCSA 6.5 using either VMware Fusion or Workstation:

Step 0 (Optional) - Familiarize yourself with setting up VCSA 6.0 was on Fusion/Workstation with this blog post which will be helpful for additional context.

Step 1 - Download & extract the VCSA 6.5 ISO

Step 2 - Import the VCSA OVA which will be located in vcsa/VMware-vCenter-Server-Appliance-6.5.0.5100-XXXXXX_OVF10.ova using either VMware Fusion or Workstation (you can either double click or just go to File->Open) but make sure you do NOT power it on after deployment. (this is very important)

Step 4 - Locate the directory in which the VCSA was deployed to and open up the VMX file and append one of the following options (make sure to change the IP information and passwords based on your environment):

Option 1 (Stage 1 & 2 Configuration):

guestinfo.cis.deployment.node.type = "embedded"
guestinfo.cis.appliance.net.addr.family = "ipv4"
guestinfo.cis.appliance.net.mode = "static"
guestinfo.cis.appliance.net.pnid = "192.168.1.190"
guestinfo.cis.appliance.net.addr = "192.168.1.190"
guestinfo.cis.appliance.net.prefix = "24"
guestinfo.cis.appliance.net.gateway = "192.168.1.1"
guestinfo.cis.appliance.net.dns.servers = "192.168.1.1"
guestinfo.cis.appliance.root.passwd = "VMware1!"
guestinfo.cis.appliance.ssh.enabled = "True"
guestinfo.cis.deployment.autoconfig = "True"
guestinfo.cis.appliance.ntp.servers = "pool.ntp.org"
guestinfo.cis.vmdir.password = "VMware1!"
guestinfo.cis.vmdir.site-name = "virtuallyGhetto"
guestinfo.cis.vmdir.domain-name = "vsphere.local"
guestinfo.cis.ceip_enabled = "False"

Option 2 (Stage 1 Only Configuration):

guestinfo.cis.deployment.node.type = "embedded"
guestinfo.cis.appliance.net.addr.family = "ipv4"
guestinfo.cis.appliance.net.mode = "static"
guestinfo.cis.appliance.net.pnid = "192.168.1.190"
guestinfo.cis.appliance.net.addr = "192.168.1.190"
guestinfo.cis.appliance.net.prefix = "24"
guestinfo.cis.appliance.net.gateway = "192.168.1.1"
guestinfo.cis.appliance.net.dns.servers = "192.168.1.1"
guestinfo.cis.appliance.root.passwd = "VMware1!"
guestinfo.cis.appliance.ssh.enabled = "True"
guestinfo.cis.deployment.autoconfig = "False"
guestinfo.cis.ceip_enabled = "False"

Step 5 - Once you have saved your changes, go ahead and power on the VCSA. At this point, the guestinfo properties that you just added will be read in by VMware Tools as the VCSA is booting up and the configuration will begin. Depending on the speed of your hardware, this can potentially take up to 15min+ as I have seen it. Please be patient with the process. If you wish to check the progress of the deployment, you can open a browser to https://[VC-IP]:5480 and you should see some progress or you can periodically connect to the Hostname/IP Address and once it is done, you should be taken to the vCenter Server's main landing page.

Virtual NVMe and Nested ESXi 6.5?

10.26.2016 by William Lam // 4 Comments

After publishing my Nested ESXi enhancements for vSphere 6.5 article, I had received a number of questions on whether the new Virtual NVMe (vNVMe) capability introduced in the upcoming vSphere 6.5 release would also work with a Nested ESXi VM? The answer is yes, similiar to PVSCSI and VMXNET3, we also have an NVMe driver for ESXi running in VM.

Disclaimer: Nested ESXi and Nested Virtualization is not officially supported by VMware, please use at your own risk.

To consume the new vNVMe for a Nested ESXi VM, you will need to use the latest ESXi 6.5 and later compatibility (vHW 13). Once that has been done, you can then add the a new NVMe Controller to your Nested ESXi VM and then assign that to one of the virtual disks as shown in the screenshot below.

nested-esxi-65-nvme-1
Next, you would install ESXi 6.5 as you normally would and the NVMe controller will automatically be detected and driver will be loaded. In the example below, you can see I only have a single disk which ESXi itself is installed on and it is backed by the NVMe Controller.

nested-esxi-65-nvme-0
One of the biggest benefit of using an NVMe interface over the traditional SCSI is that it can significantly reduce the amount of overhead compared to the SCSI protocol which in turn consumes less CPU cycles as well as reducing the overall amount of IO latency for your VM workloads. Obviously, when using it inside of a Nested ESXi VM, YMMV but hopefully you should also see an improvement there as well. For those who plan to give this a try in their environment, it would be good to hear what type of use cases you might have in mind for this and if you have any feedback (good/bad), feel free to leave a comment.
