Meltdown and Spectre

 

Happy New Year … Not!

With the New Year comes a new class of malicious attack that can impact IT systems. This time, the attack is hardware based, affecting mostly Intel based systems, and to some extent, AMD systems as well.

Here is a list of resources that highlight what it is all about and how to mitigate against this new threat. In the words of Microsoft, “Don’t panic.”

PODCAST: Hybrid Cloud Strategy options

Protect your Virtual Machines to the Cloud with Azure Site Recovery

Great news!

Microsoft have now made it possible to protect your Virtual Machines running on a Hyper-V server with Windows Server 2012 R2 by replicating them to Azure. In the past, this was only available for larger organizations that had access to System Center Virtual Machine Manager. Now, SMBs can take advantage of this service out of the box from Hyper-V without the need to purchase the SCVMM components.

Here is the link to the documentation on how to set this up – http://azure.microsoft.com/en-us/documentation/articles/hyper-v-recovery-manager-hypervsite/

12 Common Hyper-V Deployment Mistakes

HyperV

Altaro have put out a blog on 12 of the common Hyper-V deployment mistakes that people make. I think I have done a few of these before!

  1. Mis-Provisioning Resources in Hyper-V
    • Improper Balance of CPU and Memory
    • Improper Balance of Networked Storage and Network Connectivity
    • Improper Balance of SSD and Spinning Disks
    • Improper Balance of Networking Resources
    • Improper Focus of Resources
  2. Creating Too Many Networks and/or Virtual Adapters
  3. Creating Too Many Virtual Switches
  4. Optimizing Page Files
  5. Not Leveraging Dynamic Memory
  6. Leaving Default VM Configurations
  7. Not Troubleshooting the Right Thing
  8. Overloading the Management Operating System
  9. Leaving the Management OS in Workgroup Mode When there is a Perfectly Good AD Domain Available
  10. Not Testing
  11. Avoiding PowerShell
  12. Not Figuring Out Licensing in Advance

Microsoft® Virtual Machine Converter (MVMC) 3.0 released

Microsoft has just released version 3 of their Virtual Machine Converter (MVMC). This is a standalone tool that will covert virtual machines, hosts and physical machines to Hyper-V.

The new features of MVMC 3.0 include:

  • Converts virtual disks that are attached to a VMware virtual machine to virtual hard disks (VHDs) that can be uploaded to Microsoft Azure.
  • Provides native Windows PowerShell capability that enables scripting and integration into IT automation workflows.
  • Note The command-line interface (CLI) in MVMC 1.0 has been replaced by Windows PowerShell in MVMC 2.0.
  • Supports conversion and provisioning of Linux-based guest operating systems from VMware hosts to Hyper-V hosts.
  • Supports conversion of offline virtual machines.
  • Supports the new virtual hard disk format (VHDX) when converting and provisioning in Hyper-V in Windows Server® 2012 R2 and Windows Server 2012.
  • Supports conversion of virtual machines from VMware vSphere 5.5, VMware vSphere 5.1, and VMware vSphere 4.1 hosts Hyper-V virtual machines.
  • Supports Windows Server® 2012 R2, Windows Server® 2012, and Windows® 8 as guest operating systems that you can select for conversion.
  • Converts and deploys virtual machines from VMware hosts to Hyper-V hosts on any of the following operating systems:
    -Windows Server® 2012 R2
    -Windows Server® 2012
    -Windows Server 2008 R2 SP1
  • Converts VMware virtual machines, virtual disks, and configurations for memory, virtual processor, and other virtual computing resources from the source to Hyper-V.
  • Adds virtual network interface cards (NICs) to the converted virtual machine on Hyper-V.
  • Supports conversion of virtual machines from VMware vSphere 5.5, VMware vSphere 5.0, and VMware vSphere 4.1 hosts to Hyper-V.
  • Has a wizard-driven GUI, which simplifies performing virtual machine conversions.
  • Uninstalls VMware Tools before online conversion (online only) to provide a clean way to migrate VMware-based virtual machines to Hyper-V.
  • Important MVMC takes a snapshot of the virtual machine that you are converting before you uninstall VMware Tools, and then shuts down the source machine to preserve state during conversion. The virtual machine is restored to its previous state after the source disks that are attached to the virtual machine are successfully copied to the machine where the conversion process is run. At that point, the source machine in VMware can be turned on, if required.
  • Important MVMC does not uninstall VMware Tools in an offline conversion. Instead, it disables VMware services, drivers, and programs only for Windows Server guest operating systems. For file conversions with Linux guest operating systems, VMware Tools are not disabled or uninstalled. We highly recommend that you manually uninstall VMware Tools when you convert an offline virtual machine.
  • Supports Windows Server and Linux guest operating system conversion. For more details, see the section “Supported Configurations for Virtual Machine Conversion” in this guide.
  • Includes Windows PowerShell capability for offline conversions of VMware-based virtual hard disks (VMDK) to a Hyper-V–based virtual hard disk file format (.vhd file).
