Linux runs on Hyper-V – you’ve seen Hanna Montana Linux here already (I couldn’t resist using it!). I do hope you’ll look to Windows Server first as your preferred application platform, but realize that sometimes business conditions may lead you to run other operating systems in your data center. The Linux Integration Components for Hyper-V help optimize performance in such mixed environment.
Since the Hyper-V Integration Components were contributed to Linux, they’ve been included in recent versions of the Linux kernel. With distributions based on newer builds of the Linux kernel (2.6.32 and after) you can add high performance support for Hyper-V without the need to download the Linux Integration Components (ICs) from Microsoft.
I ran through the process this weekend with the latest version of Ubuntu desktop that I could find (10.04 workstation). It’s based on the 2.6.32 version of the Linux kernel, and includes the ICs for Hyper-V.
Once I had it all loaded, I did the following inside the VM:
I later removed the legacy emulated NIC (no need for two NICs in this VM), and can now also add lots more disks using the synthetic SCSI adapter. The ICs work great, and the VM is really responsive, but the version of the Integration Components is not the exact same one that Windows Server 2008 R2 is expecting. With some versions of the, ICS you might see some interesting notes in your event log, like those below:
Don’t worry, the ICs work just fine as it says in the event log. The comment about support can show up for any version of Linux – whether it is supported or not due to the timing related to the code release.
Note that Ubuntu is not a distribution that is currently supported by Microsoft on Hyper-V, but it does have the IC code included, and seems to work pretty well!
Once other distributions start to leverage 2.6.32 and newer versions of the Linux kernel, you should be able to use a similar process to enhance Linux performance on Hyper-V.
Thank you SO much for this awesome post!!! It is so straightforward and simple. You are doing a really great job! Keep up the fine work!!
jw - glad you liked the post - sorry for not replying sooner (new blog platform has me all messed up!).
When LIS 3.4 in Ubuntu 12.10/13.04? Or Linux Kernel?
