MacOS 11 (Big Sur) Beta 1 on ESXi

06/24/2020 by William Lam 10 Comments

The first Beta of Apple MacOS 11 (Big Sur) was just released a couple of days ago and I know folks are excited to start kicking the tires. Some folks have noticed when to installing Big Sur running on VMware Fusion, the following error is observed:

BIErrorDomain error 3

From the suggested workarounds, it looks like the MacOS installer was somehow unable to detect that the underlying hardware was Apple which causes this generic error to be thrown. Interestingly, this was the same error I came across when attempting to install Big Sur on ESXi 7.0. Instead of having to lookup your physical Apple hardware IDs and specify several VM Advanced Settings, you can simply add the following setting which will accomplish the same behavior:

smbios.reflectHost = "TRUE"

After the setting has been applied, the error should go away and you should be able to upgrade from an existing MacOS deployment to Big Sur. This issue has already been reported internally at VMware and I have also shared with the teams the quick workaround.

Here is Big Sur on ESXi 7.0 running on an Apple Mac Mini 2018 (requires ESXi 7.0b patch VMware-ESXi-7.0b-16324942)

Here is Big Sur on ESXi 6.7 Update 3 running on an Apple Mac Mini 2018 (requires ESXi 6.7 Patch 02 ESXi670-202004002)

Update on ESXi on Apple Mac Mini 2018 & Mac Pro 2019

04/28/2020 by William Lam 19 Comments

Although there has not been any news in some time regarding the support for ESXi on the latest Apple Mac Mini 2018 and the recently released Apple Mac Pro 2019, there has definitely been work happening behind the scenes at VMware. Today, I would like to share a pretty significant update as a result of some of these efforts.

MacOS Guest

One of the biggest issue which I had observed when using a T2-based Apple system with ESXi is that it would fail to boot a MacOS Guest and just keep rebooting the VM. I am very happy to announce that this issue has been resolved and ESXi can now properly recognize the Apple System Management Controller (SMC) device which is used as part of the MacOS Guest start up process. This now means a MacOS Guest will be able to properly boot on a T2-based Apple system.

Thunderbolt 3

Another impact of a T2-based Apple system with ESXi is that storage and networking devices connected to the Thunderbolt 3 ports are not visible. I am also happy to announce that this issue has been resolved and ESXi can now see PCIe devices that are attached to the Thunderbolt 3 ports.

An ESXi Advanced Setting change is required for Thunderbolt 3 to work correctly and the following command will need to be executed after installing ESXi:

esxcli system settings kernel set -s pciExperimentalFlags -v 16

Once the setting has been applied, a system reboot will be required and your PCIe devices will show up properly. In future, this additional configuration may not be required and can be detected based on the underlying hardware.

Both of the fixes mentioned above are included in the latest ESXi 6.7 Patch 02 (ESXi670-202004002) release which is available today! Hopefully this was the news that many of you have been waiting for 😀

UPDATE (06/25/20) - The Apple 2018 Mac Mini 8,1 is now officially on the VMware HCL and is fully supported with ESXi 7.0b, which contains the fixes mentioned above. See note below on 06/23 for more information.

UPDATE (06/23/20) - ESXi 7.0b has just been released and contains fixes for both the MacOS guest boot issue support for Thunderbolt 3 devices which now enables support for the vSphere 7 release. One additional enhancement, customers no longer need to configure the ESXi Advanced Setting to enable Thunderbolt 3 support, this is now automatically configured based on detecting an Apple hardware system such as an Apple Mac Mini 2018 or Apple Mac Pro 2019. This is a patch release and you will need to go to the VMware Patch Portal site to download and apply the update.

Now, before you rush out to start deploying MacOS Guests on either the Mac Mini or Mac Pro, I do have to mention that neither the Mac Mini 2018 or the Mac Pro 2019 will be officially supported by VMware. Due to the current situation that we are all in with COVID-19, personnel access to VMware facilities like many other organizations has been severely restricted and/or prohibited. In fact, much of the early validation was done by yours truly using a Mac Mini 2018 which I had access to (Thanks Michael Roy) as Engineering did not have access to hardware during the shelter in place orders. This also means that certifications of these platforms is still on-going and until these systems are officially listed on VMware's HCL, they will not be officially supported by VMware.

Disclaimer: VMware currently does not officially support the Apple 2019 Mac Pro7,1

A trip down memory lane with the vSphere C# Client and ESXi 6.7 & 7.0

Those with a keen eye quickly realized there was more to my tweet than meets the eye 😉 but the majority of folks quickly admitted they were fooled by the nice "April Fools" joke ... but was it really a joke?

USB Native Driver Fling for ESXi adds support for Multi-Gig (1G/2.5G/5G) Adapter

09/27/2019 by William Lam 9 Comments

Today, we have an exciting update to give on our USB Network Native Driver for ESXi Fling which has had two updates since releasing earlier this year and has been extremely well received by the VMware community. As many of you know, I am always on the look out for new and innovative tech that can help enable our customers, especially when it comes to building home labs to learn about the latest and greatest VMware software.

UPDATE (06/08/20) - QNAP has just published the updated firmware for their QNA-UC5G1T USB NIC which resolves some of the performance issue observed with the initial release.

Several months back, I came to learn about a really cool USB-based Multi-Gigabit Network Adapter (QNA-UC5G1T) from QNAP which can negotiate with speeds up to 1Gbps, 2.5Gbps and 5Gbps. I was not familiar with the multi-gig specification but it it looks like it was created as a standard back in 2016 as IEEE 802.3bz. This initially evolved from advancements in wireless technology but more recently it started to make its way into ethernet-based devices.

Although this particular device is from QNAP, the underlying chipset is actually from Aquantia, now part of Marvell. If the name sounds familiar, it should as Aquantia is also the vendor to Apple for their 10GbE NICs in both the 2018 Mac Mini and new iMac Pros. In fact, their chipsets are also used in a number of Thunderbolt 3 to 10GbE NICs which also works with ESXi. Access to 10GbE is certainly more common these days but it certainly is not for everyone and not all platforms can be expanded to support it.

The QNA-UC5G1T device is not only small but because it is USB-based, you are more likely to have spare USB ports on your system than say a traditional PCIe slot or Thunderbolt 3 port. From a cost standpoint, this device is about half the cost of the 10GbE Thunderbolt adapter coming in at $79 USD and can be ordered from Amazon. As far as I know, QNAP is the only vendor who has produced a multi-gig USB adapter, but perhaps in the future, there will be other vendors.

New hardware support & enhancements to USB Network Native Driver for ESXi

06/17/2019 by William Lam 1 Comment

Since releasing the USB Network Native Driver for ESXi Fling back in February, the feedback and support for this Fling has simply been amazing. I especially enjoy hearing from customers, almost on a weekly basis, on how they are taking advantage of this solution in their vSphere/vSAN/NSX home lab and enabling for more complex networking topologies.

When we released the fling, we had focused on the most popular USB 3.0 network adaptors that we had accessed to which were based on AX8817a, AX88179 & RTL8153 chipsets. The initial list started out with just 5 devices, but we knew there were going to be others. In fact, Songtao and I have received plenty of feedback from our customers on what they would like to see supported, including USB 2.0 network adaptors. Another highly requested feature that customers have been asking for is support for Jumbo Frames and this is usually in the context of setting up either an NSX-V or NSX-T environment.

ESXi Native Driver for USB NIC Fling

02/12/2019 by William Lam 34 Comments

Today, I am very excited to announce a new Fling that I have been working on which is a Native Driver for ESXi that will enable support for three of the most popular USB network adapter chipsets found in the market today. The ASIX USB 2.0 gigabit network ASIX88178a, ASIX USB 3.0 gigabit network ASIX88179 & the Realtek USB 3.0 gigabit network RTL8153. This effort had initially started back in 2016 as a side project with Songtao, a VMware Engineer who works on our USB stack for ESXi. Based on the enormous amount of feedback from the community as well customer Production use cases, this side project evolved into the development of a full fledge Native Driver for ESXi.

This Fling is more than just adding additional network interfaces for vSphere Home Labs, which is definitely a use case, but it is also about enabling new and future computing platforms that may not always have the traditional network connectivity that we have come to expect. Today, ESXi supports a number of high-end network controllers (10G/40G/100G) designed for Enterprise Data Centers that include advanced networking & low latency features. As more & more workloads appear at the Edge like IoT, point-of-sales & remote office use cases, the traditional networking solutions may no longer meet the needs of these new infrastructures.

For Edge computing environments, reducing the cost & power consumption is definitely one of the driving factors. However, with some of these platforms, their form factors can make it difficult or impossible to support traditional high-end network controllers. Luckily, there are a number of options for network adapters in the market but is can also be difficult to support them all.

USB has become one the most widely adopted connection type in the world & USB network adapters are also popular amongst Edge computing platforms. In some platforms, there is either limited or no PCI/PCIe slots for I/O expansion & in some cases, an Ethernet port is not even available. This Fling will hopefully help enable some of these Edge use cases today and with the help of the community and feedback, we can see how this can be enhanced or evolved over time including where it could even be part of the ESXi distribution.

Another use case for USB-based network adapters as mentioned earlier are for vSphere Home Labs, platforms like the Intel NUC or Apple Mac Mini have limited number of built-in Ethernet ports, but plenty of USB & USB-C ports which can enable these platforms with additional networking capabilities. These systems could also be potential Edge platform candidates given the right connectivity.
