vmware workstation player is now 40x cheaper than oracle virtualbox

vmware workstation player is now 40x cheaper than oracle virtualbox if you need USB 2 and/or USB 3 support

due to a quirk on the oracle store the minimum order quantity of virtualbox is 40 giving a minimum cost of £4000

try and edit your cart you will get

 

the oracle site even has some broken links

virtualbox minishift openshift origin dev env

if you have virtualbox (or hyper-v) you can download minishift and create a local openshift origin demo or dev environment

to avoid the Hyper-V error you will need to run minishift with the –vm-driver switch
BAD WAY

C:\Progs\minishift-1.5.0-windows-amd64>minishift start
-- Installing default add-ons ... OK
-- Checking if Hyper-V driver is configured ... FAIL
 Hyper-V virtual switch is not set

GOOD WAY

C:\Progs\minishift-1.5.0-windows-amd64>minishift start --vm-driver virtualbox
-- Starting local OpenShift cluster using 'virtualbox' hypervisor ...
-- Minishift VM will be configured with ...
 Memory: 2 GB
 vCPUs : 2
 Disk size: 20 GB

once you have minishift openshift running locally you should be able to access its  webconsole at

and you may want to download the openshift command line tools so you can use those locally too

once you are happy minishift openshift is running locally you may like to create a project using the demo national parks container

and the demo national parks python app

you should then see something like this

virtualbox tips of the week check bios vt and dont overcommit ram

virtualbox tips of the week check bios vt and dont overcommit ram

  1. Check your BIOS and confirm VT and VT-x are enabled and then you will be able to build and run 64bit vms in your 64bit os
  2. Dont try and run 2 x 1.5G vms if you only have 4G of RAM unless you want to spend 4 hours shutting down – reduce vms to to 1G and restart them

do this
