Installing ESXi 5.1 Update 1 on Mac Mini is Now a Breeze! (No Custom ISO/patches Needed!)

by // 68 Comments

ESXi 5.1 Update 1 was just released by VMware and similar to the ESXi 5.0 Update 2 release last year, the tg3 (Broadcom) driver has now been updated to 3.123b.v50.1 which is required to support network connectivity on the Apple Mac Mini's. Prior to this, to install ESXi on an Apple Mac Mini, users were required to build a custom ISO that included the updated tg3 driver and I am happy to say this is no long necessary! In addition, having the latest driver also provides out of the box support for the Thunderbolt ethernet adapter which is great if you are looking to add an additional ethernet connection to the Apple Mac Mini.

Disclaimer: The Apple Mac Mini is not officially supported by VMware.

Here is a quick screenshot of the networking details including the Thunderbolt ethernet adapter on my Apple Mac Mini 5,3 running ESXi 5.1 Update 1:

Apple Mac Mini 6,2 Users

If you have an Apple Mac Mini 6,2 the workarounds described in this article are still required as well as an additional issue regarding the on-board NIC for the Apple Mac Mini 6,2. The issue is that the on-board NIC is not recognized and claimed by the tg3 driver because there is not a PCI ID entry in the tg3 map file. Note, BCM57766 driver is supported, just that it was missing the mapping (I believe this was the case in 5.0 as well). Working with VMware engineering, I was able to obtain the SMC fix and along with the workarounds that I built earlier for ESXi 5.0 and I have created a custom ESXi 5.1 Update 1 ISO that includes all the fixes and you will be able to install it on your Apple Mac Mini 6,2 without any further modifications.

Note: From my understanding, some of these issues have been fixed but just did not make it in time for the Update 1 release. I'm hoping that we will be able to get most of these fixed in a future patch or update. This is actually pretty awesome, given that this is NOT SUPPORTED by VMware, but engineers are still willing to help the community out!

UPDATE: When trying to enable vSphere HA, the following error "Could not find a trusted signer" is thrown. To get around this problem, you will need to manually install the vSphere HA VIB and then reconfigure vSphere HA. The easiest method is to SCP the VIB from the VCSA and then using ESXCLI and the --no-sig-check flag to install the VIB.

Here are the commands to run:

scp /etc/vmware-vpx/docRoot/vSphere-HA-depot/vib20/vmware-fdm/VMware_bootbank_vmware-fdm_5.1.0-1064983.vib [email protected]:/tmp
esxcli software vib install -v /tmp/VMware_bootbank_vmware-fdm_5.1.0-1064983.vib --no-sig-check

Installing ESXi 5.0 Update 2 on Mac Mini is Now a Breeze! (No Custom ISO/patches Needed!)

by // 15 Comments

VMware has just released ESXi 5.0 Update 2 which includes many bug fixes, but along with these fixes, these updates usually also include new inbox drivers as part of the default ISO image for ESXi. One important driver that I had noticed while going through the release notes is the inclusion of the tg3 (Broadcom) inbox driver:

  • Updates the tg3 driver to version 3.123b.v50.1
    The tg3 inbox driver version shipped with the ESXi 5.0 Update 2 is 3.123b.v50.1.

Why is this awesome!? Well, for those of you who own an Apple Mac Mini and would like to run ESXi, may recall an additional step is required to create a customized ESXi ISO to include an updated tg3 driver for the networking stack to function in an Apple Mac Mini. Though the steps have been documented here, it is great to see this working right out of the box using the new ESXi 5.0 Update 2 ISO from VMware. In addition to the networking stack functioning properly after installation, it also enables connectivity to an Apple Thunderbolt Ethernet adapter if you happen to have one connected to your Apple Mac Mini! You no longer have to create a custom ESXi ISO for the Thunderbolt Ethernet adapter as mentioned in an earlier article here.

Note: This article is only relevant to pre-2012 Apple Mac Mini, if you have a newer Apple Mac Mini 6,2 - Please refer to this article for installation.

Here are a few screenshots of running the latest ESXi 5.0 Update 2 on my Apple Mac Mini 5,3 as well as showing the Apple Thunderbolt Ethernet adapter active in ESXi:

If you want a tiny form factor for a vSphere home lab, you should definitely consider asking Santa for an Apple Mac Mini this Christmas 😉 Hope everyone has a Happy Holiday and Happy New Years! 

Thunderbolt Ethernet Adapter in Apple Mac Mini on ESXi 5

by // 27 Comments

If you followed Apple's recent announcement at their WWDC conference then you would know that they just released a Thunderbolt to Gigabit Ethernet adapter. So, why am I talking about this? Well if you are running ESXi 5 on an Apple Mac Mini like me, then you are probably wondering if you can get another network interface on the Mini as it only has a single network adapter. The answer is YES!

To get ESXi 5 to recognize the Thunderbolt adapter, you will need to download and install an additional Broadcom driver (tg3 3.123b.v50.1) or you can create a customized ISO with the driver built in using the steps outlined here for a new installation.

UPDATE (12/21): A custom ESXi ISO is no longer needed, you can use ESXi 5.0 Update 2 which includes the necessary driver to support Thunderbolt Ethernet adapter. Please take a look at this article here for the details.

If you are just installing the driver on an existing ESXi 5 installation, extract the offline bundle and upload to your ESXi host and run the following command:

esxcli software vib install -d /vmfs/volumes/mini-local-datastore-1/tg3-3.123b.v50.1-offline_bundle-682322.zip

Here is the output from ESXCLI on how ESXi sees the Thunderbolt adapter:

As you can see, it shows up with no description for the device and this is the same when running lspci, it just shows up as a network controller from Broadcom. This is not a big deal, but I assume this has something to do with the high numbering of the vmnic instead of being vmnic1 it's vmnic32.

I also performed some basic network testing by yanking the ethernet cable on the onboard network adapter and ensured traffic continued to flow and vice versa with the other Thunderbolt adapter. Everything works beautifully and now you can have some network redundancy built into your Mac Mini or if you need the throughput for all those VMs you plan on running 😉

Big thanks to Randy K. for hooking me up with a Thunderbolt adapter!
