Keys

The hypervisor keys are available for free. To obtain one:

The license key 'VMware vSphere Hypervisor 6 License' works on all 6.x hypervisors.

Installation

The easiest way is to just burn the iso image and install via CD/DVD.

But if your server doesn't have a CD/DVD reader, you can try getting a USB stick.

USB Stick

## Set up the USB drive
root@nas:/mnt/iso# fdisk /dev/sdk

Welcome to fdisk (util-linux 2.28.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Command (m for help): o
Created a new DOS disklabel with disk identifier 0xde56333a.

Command (m for help): p
Disk /dev/sdk: 14.7 GiB, 15720251392 bytes, 30703616 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0xde56333a

Command (m for help): n
Partition type
   p   primary (0 primary, 0 extended, 4 free)
   e   extended (container for logical partitions)
Select (default p): p
Partition number (1-4, default 1):
First sector (2048-30703615, default 2048):
Last sector, +sectors or +size{K,M,G,T,P} (2048-30703615, default 30703615):

Created a new partition 1 of type 'Linux' and of size 14.7 GiB.

Command (m for help): t
Selected partition 1
Partition type (type L to list all types): c
Changed type of partition 'Linux' to 'W95 FAT32 (LBA)'.

Command (m for help): a
Selected partition 1
The bootable flag on partition 1 is enabled now.

Command (m for help): wq
The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.

## Format the drive
root@nas:/mnt/iso# mkfs.vfat -F 32 -n USB /dev/sdk1
mkfs.fat 4.1 (2017-01-24)

## Use the syslinux utility (from syslinux-nonlinux-6.04-0.1.fc25.noarch)
root@nas:/mnt/iso# syslinux /dev/sdk1
root@nas:/usr# cat /usr/share/syslinux/mbr.bin > /dev/sdk

## Copy the files
root@nas:/mnt# mount /dev/sdk1 usb
root@nas:/mnt# cp -r iso/* usb

## Edit the syslinux.cfg file
root@nas:/mnt/usb# mv isolinux.cfg syslinux.cfg

## Edit syslinux.cfg so that the APPEND line is 'APPEND -c boot.cfg -p 1'
root@nas:/mnt/usb# cat syslinux.cfg
DEFAULT menu.c32
MENU TITLE ESXi-6.5.0-20170104001-standard Boot Menu
NOHALT 1

  APPEND -c boot.cfg -p 1
  MENU LABEL ESXi-6.5.0-20170104001-standard ^Installer

  MENU LABEL ^Boot from local disk

## Unmount the image

Updating

6.0 to 6.5

Download the offline depot package and apply the update: 

# esxcli software profile update -p ESXi-6.5.0-4564106-standard -d /vmfs/volumes/vol/VMware-ESXi-6.5.0-4564106-depot.zip

This package requires a subscription. If you're using the free license, either get the evaluation or install the update by booting with the ISO image.

5.5 to 6.0

To update a ESXi install from 5.5 to 6.0, download the ESXi 6.0 offline bundle and upload it to a datastore on the server.

Log in via SSH and execute 

# esxcli software vib update -d /vmfs/volumes/datastore1/ESXi600-201504001.zip

Then reboot to apply the changes.

Troubleshooting

IOMMU Hangs

If your ESXi server hangs while "Initializing IOV", disable IOMMU by appending 'noIOMMU' to the kernel immediately after the new kernel boots by hitting Shift-O (letter O, not zero)

To make the changes persistent, add it to the boot arguments in /bootbank/boot.cfg
