If you try to start OC appliance (Ubuntu_14.04-owncloud-9.1.4-1.1-201702081724-disk1.vmdk) on VMware ESXI, you will probably get an error:

Failed to start the virtual machine.
Module DevicePowerOn power on failed.
Unable to create virtual SCSI device for scsi0:0, '/vmfs/volumes/56fab8a0-35277bdd-7efd-002590149f36/Virtualke/OwnCloud_9.1.4/Ubuntu_14.04-owncloud-9.1.4-1.1-201702081724-disk1.vmdk'
Failed to open disk scsi0:0: Unsupported or invalid disk type 7. Ensure that the disk has been imported.

I am sure that there is a better way but workaround that I've found (https://www.youtube.com/watch?v=Xld8MbVQdbE) is to load the .vmx to VMware workstation first, and then upload it to ESXI. After that it will start without error message !

By default your OC appliance is configured to get the IP address from DHCP server. If you want to fix your IP address and don't know much about Linux, you can do it like this:
https://help.ubuntu.com/community/NetworkConfigurationCommandLine/Automatic

1. On OC console login as admin.
2. Type

sudo -i

3. Type

ip addr

This will list the interface names for all NICs on your computer. It will probably include eth0 (hardwired NIC), lo (loopback interface for the localhost), and something for your wireless card (like wifi0, or wlan0).
