ESXi 6.5: Intel NICs Not Found

While playing around with an ESXi 6.5 test system, I accidentally killed all network connectivity by setting the NICs to pass-through. This post gives a bit of background and the solution that worked for me.

The system is home-built with a Fujitsu D3410-B2 motherboard and an Intel dual-port Gigabit NIC (HP OEM). The motherboard has a Realtek RTL8111G chip for its NIC, which does allegedly work with community drivers, but not out-of-the-box. One of the things I want to run on this box is a pfSense router. So, when I discovered, that the Realtek NIC was available for pass-through, I enabled this. I also enabled one(!) of the two ports of my Intel dual-port NIC. At least, that is what I had intended to do.

Because what really happened was that all three NICs were set to pass-through, which of course meant that ESXi itself had no NIC available to itself any more. This issue showed after the next reboot, when the console told me that no supported NICs had been found in the system. Perhaps not wrong in strict terms, but certainly a bit misleading, when you are not very experienced with ESXi.

Searching the net did not provide a real answer. But after a couple of minutes I realized that perhaps my change about pass-through might be the culprit. The relevant file where these settings are stored is /etc/vmware/esx.conf. I searched for lines looking like this

/device/000:01.0/owner = "passthru"

and replaced them with

/device/000:01.0/owner = "vmkernel"

After that I just had to reboot and things were fine again.

 

VMware Fusion 4 on OS X Mavericks

Having upgraded to OS X Mavericks just recently, one of the main questions for me was, whether I would need to upgrade from VMware Fusion 4 to the current version (which is Fusion 7). Initially the thought had not really occurred to me, but after the second crash of my MacBook I started to look around. The majority of content I found was about the support status and some people had gotten really agitated during the discussion. But little was said about the technical side of things, i.e. whether the stuff was working or not.

What I can say today is that for me VMware Fusion 4.1.4 works nicely and without issues so far. I use it almost exclusively to run a company-provided Java development environment on Windows 7 64 bit. So no 3D graphics, USB drives, or other “fancy” things.

The crashes were most like caused by an old version of the keyboard remapping tool Karabiner (formerly KeyRemap4MacBook). Once I had upgraded to the appropriate version, the crashes were gone.

CentOS 5.4 64 bit does not work with ESXi 4.1

I have recently tried to install the 64 bit version of CentOS 5.4 on ESXi 4.1, but without much success. It stalls immediately after start (also in text mode) and all I got was a non-flashing underscore or dash. Several people reported similar problems. The general recommendation is to enable virtualisation support (VT) in the ESXi host’s mainboard BIOS. However, I had already installed other 64 bit OSes and therefore doubted this would help. Instead I simply tried CentOS 5.5 x86-64 and this immediately solved the issue.
