Ubuntu and Hyper-V: The Paths to Enlightenment

As part of virtualization on Hyper-V, there is the ability to use Para-virtualized drivers instead of using built-in drivers for slower, emulated devices. Para-virtualized drivers are simply device drivers that are written for native virtual devices. In other words they are not emulating a pre-existing physical device. The Path to Enlightenment is simply the method you use to take an operating system and enable it to use these synthetic devices.

In this article we will be describing the different methods of enabling enlightenment on Ubuntu Linux for the following 3 categories: Ubuntu 9.04 and Earlier, Ubuntu 9.10, and Ubuntu 10.04. Each of these distribution versions has significant differences which require sometimes slightly and sometimes major differences in procedure.

Enabling Jumbo Frames on Hyper-V 2008 R2 Virtual Switches

When using a Core version of Hyper-V 2008 R2, be it Hyper-V Server 2008 R2 or Windows Server 2008 R2 Standard Core, you are doing a good thing to conserve resources and minimize the attack footprint of your virtualization hosts. However this comes at a price. One of the most obvious misses in this matter is the enabling of Jumbo Frames on the Virtual Switch Interface. This enables your guests to reach out to storage directly using jumbo frames (mtu size of greater than 1500 bytes – however in this article we will be working specifically with 9000 bytes).

Installing Linux Integration Components v2.1 Beta

On March 31, 2010 Microsoft released the beta of version 2.1 of the Linux Integration Components. The Linux ICs allow Linux VMs running on Hyper-V to be “enlightened” and have access to synthetic device drivers which perform much faster than their emulated counter parts. It can be downloaded by registering for the Linux Integration Services for Hyper-V on http://connect.microsoft.com

Hyper-V Guests: Linux Integration Components (v2) on Oracle Enterprise Linux

In this article I am documenting the process for installing the Hyper-V Integration Components (v2) within a Oracle Enterprise Linux 5.3 VM. My environment consists of x64 VMs, I have not taken the time to test this process for x86 VMs, however it should hold true, as long as you update the package names to reflect the appropriate architecture.

Hyper-V Guests: Linux Integration Components on RHEL and CentOS

In this article I am documenting the process for installing the Hyper-V Integration Components within a Red Hat Enterprise Linux 5.3 or a CentOS 5.3 VM. My environment consists of x64 VMs, I have not taken the time to test this process for x86 VMs, however it should hold true, as long as you update the package names to reflect the appropriate architecture.

Hyper-V Guests: Linux Integration Components Ubuntu and Debian

In this article I am documenting the process for installing the Hyper-V Integration Components within a Ubuntu or Debian VM. I am specifically writing this for Ubuntu 8.04.2 and Debian 5, however I have additionally confirmed that this process works on both Ubuntu 8.10 and Ubuntu 9.04. My environment consists of x64 VMs, I have not taken the time to test this process for x86 VMs, however it should hold true, as long as you update the package names to reflect the appropriate architecture.
