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
