Stuck at a Black Screen and Connecting on a vCloud console

On a computer running Windows 7 x64 SP1 Enterprise running Internet Explorer 11 browser, I had issues connecting to the console of Virtual Machines hosted by VMWare vCloud.

vCloud Console black screen

This was resolved by completing the following:

  1. Adding the website to the Trusted Site list
  2. Adding the website to Internet Explorer’s compatibility list
  3. Updating Java on the workstation to the newest

Guide to using Hyper-V

Introduction to Hyper-V

 

Hyper-V is an emulation/hyper-visor Microsoft developed technology – similar to VMWare Workstation or ESXI that allows you to run Virtual Machines and different workloads simultaneously. Hyper-V is currently available in Windows 8, Windows Server 2008, Windows Server 2008 R2, Windows 8.1 & Windows Server 2012, Windows Server 2012 R2. The Hyper-V hypervisor allows multiple workloads to run on the same physical hardware that in the past would have otherwise only been suitable for one workload – allowing for power and resource efficiency.

 

Hyper-V Specifications

 

Host operating system:

To install the Hyper-V role, Windows Server 2008, Windows Server 2008 R2 Standard, Enterprise or Datacentre edition, Windows Server 2012 Standard or Datacentre edition, or Windows 8 (or 8.1) Pro or Enterprise edition is required. Hyper-V is only supported on x86-64 variants of Windows. It can be installed regardless of whether the installation is a full or core installation. Processor: An x86-64 processor

Hardware-assisted virtualization support: This is available in processors that include a virtualization option; specifically, Intel VT or AMD Virtualization (AMD-V, formerly code-named “Pacifica”).

A NX bit-compatible CPU must be available and Hardware Data Execution Prevention (DEP) must be enabled.

Although this is not an official requirement, Windows Server 2008 R2 and a CPU with second-level address translation support are recommended for workstations.

Second-level address translation is a mandatory requirement for Hyper-V in Windows 8

Memory

Minimum 2 GB. (Each virtual machine requires its own memory, and so realistically much more.)

Windows Server 2008 Standard (x64) Hyper-V full GUI or Core supports up to 31 GB of memory for running VMs, plus 1 GB for the Hyper-V parent OS.]

Maximum total memory per system for Windows Server 2008 R2 hosts: 32 GB (Standard) or 2 TB (Enterprise, Datacentre)

Maximum total memory per system for Windows Server 2012 hosts: 4 TB

Guest operating systems

Hyper-V in Windows Server 2008 and 2008 R2 supports virtual machines with up to 4 processors each (1, 2, or 4 processors depending on guest OS-see below)

Hyper-V in Windows Server 2012 supports virtual machines with up to 64 processors each.

Hyper-V in Windows Server 2008 and 2008 R2 supports up to 384 VMs per system.

Hyper-V in Windows Server 2012 supports up to 1024 active virtual machines per system.

Hyper-V supports both 32-bit (x86) and 64-bit (x64) guest VMs.

 

Improvements of Hyper-V in Windows Server 2012

 

Hyper-V Extensible Virtual Switch

Network virtualization

Multi-tenancy

Storage Resource Pools

.vhdx disk format supporting virtual hard disks as large as 64 TB with power failure resiliency

Virtual Fibre Channel

Offloaded data transfer

Hyper-V replica

Cross-premise connectivity

Cloud backup

 

Installing Hyper-V in Windows 8 & Windows 8.1

 

  1. Navigate to Control Panel & select Uninstall a Program underneath programs
  2. Select Turn Windows Features On or Off
  3. Check Hyper-V & Hyper-V Platform and select additional relevant features – I would HIGHLY recommend Hyper-V GUI Management Tools.
  4. Windows will go through and install the Hyper-V modules onto the Windows 8 workstation. Once completed the workstation will need a restart and you will be able to now fully utilise Hyper-V!

 

Installing Hyper-V for Windows Server 2012

 

  1. Open Server Manager
  2. Click Add Roles and Features and click Next
  3. Select Hyper-V Role and click Next
  4. Select the appropriate NIC (network interface card) for live migration and select Next
  5. Select the default locations for your VHD (virtual hard disks) and VM (virtual machine) configuration files to be held and select Next
  6. Once the Hyper-V role has been fully installed – restart the Windows Server 2012 machine. You should now have access to the Hyper-V Manager.

 

Hyper-V Tips and Tricks

 

How to stop and restart the Hyper-V service

 

  1. Open Hyper-V Manager
  2. Select the relevant Hyper-V server
  3. Select Stop Service

 

How to create a new Virtual Machine in Hyper-V

 

  1. Open Hyper-V Manager
  2. Select New and Virtual Machine
  3. The before you Begin Wizard will now appear – click Next
  4. Choose a name for your Virtual Machine and verify the storage location is for the virtual machine is appropriate and click Next
  5. Here you can select the “generation” of the Virtual Machine.
  6. Generation 1 – These are for 32bit legacy based systems usually used for Windows 7 and Windows XP/Linux virtual machines.
  7. Generation 2 – These are for Windows Server 2012 or 64bit versions of Windows 8
  8. NOTE: Once Virtual Machine generation has been selected – YOU CANNOT change it.
  9. NOTE: Using Convert-VMGeneration script you can convert a Generation 1 VM to Generation 2.
  10. You can now select the RAM amount you would like to delegate to your Virtual Machine and select Next
  11. If you have VLAN setup you can set your Virtual Machine to use the connection – I don’t so I am just going to click Next
  12. Now you can specify the appropriate VHD (Virtual Hard Disk) for the Virtual Machine to use – you can either create a new one or use an existing VHD.
  13. This is where you specify the path to your installation media for your virtual machine – such as an OS (operating system) ISO.
  14. You have finally setup your new Virtual Machine! Verify all the settings are correct and click Finish to configure and generate your new Virtual Machines.
  15. You can now right click on your Virtual Machine under the Hyper-V Manager and select Connect… to start it.

Free Internet Explorer – Development Virtual Machines

I have recently found a good web resource – 90 day restricted Virtual Machines, compatible with Hyper-V/VMWare & Virtual box that I thought I would share.

These Virtual Machines are intended for web development testing and include Windows XP machines running Internet Explorer 6 to Windows 8.1 machines running Internet Explorer 11 (as of this post).

  1. To access these Virtual Machines – go to: Modern.ie and select “Get Free VMs” to see the download list.

Note: This website also has a modern interface – with a lot of resources for webpage development in Internet Explorer. Useful for any webpage builder and is developed by Microsoft.
