Building your own Debian Kernel packages for Hyper-V Support
Posted in Linux Server, Virtual Machine Manager | 23 Comments | 28,717 views | 07/01/2011 16:51

If you have a kernel image for your Linux virtual machine, it’s easy to upgrade your kernel for Hyper-V support.

1) Install a clean Debian virtual machine (Use emulated Ethernet card and 1 vCpu)

2) Use commands below to update your virtual machine:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
nano /etc/apt/sources.list (edit your source list if it needs)
apt-get update
aptitude update
apt-get install openssh-server (for ssh support)
apt-get install build-essential 
apt-get install ncurses-dev kernel-package fakeroot
apt-get install linux-headers-`uname -r`
apt-get install linux-source-`uname -r | awk -F"-" '{print $1}'`
cd /usr/src
wget -c http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.36.tar.bz2
bzip2 -d linux-2.6.36.tar.bz2
tar xf linux-2.6.36.tar
cd linux-2.6.36
cp /boot/config* ./.config
make menuconfig

At menuconfig, go to:

Device Drivers -> Stagging Drivers

Now choose Microsoft Hyper-V Client Drivers

After that you can enter to exit with saving changes.

Use commands below to continue:

1
2
make-kpkg clean
fakeroot make-kpkg --initrd --append-to-version=-hyperv kernel_image kernel_headers

After this process, you will find your two .deb files in /usr/src directory.

Possible problems:

1) You may get this error when you try to compile kernel.

1

6
This is kernel package version 11.015.
The UTS Release version in include/linux/version.h
"" 
does not match current version:
"2.6.26-hyperv" 
Please correct this.

Please check this page to fix this issue:

2) You may get this error when you try to compile kernel.

lguest.c: In function ‘create_thread’:

If you get different problems, please report to me.

Thank you so much for this guide, it worked perfect with kernel 2.6.38.2 on Debian 6.0.1

Cheers :)

Hi Yusuf!
I have HyperV SP1 and Debian 6.0.1. I make this guide step by step and have a problem. Sqeeze boot too long with the new kernel (about 2 minutes).
Running lsmod | grep ‘hv’ show’s me that:
hv_timesource
hv_vmbus

and repeating message in console “task modprobe blocked for more than 120 seconds”

What wrong ? :)

Why, oh WHY ? downloading a kernel from an untrusted source ?
> wget -c http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.36.tar.bz2

This step is absolutely useless (aptitude already downloaded it) and potentially harmful.

Also replacing the kerning is probably not the better way to handle Hyper-V, as it prevents future kernel updates on the machine.
A better way is to compile the kernel by just issuing “make” and copy the kernel modules:

mkdir /lib/modules/2.6.32-5-686/kernel/drivers/staging/hv/
cp drivers/staging/hv/hv_vmbus.ko /lib/modules/2.6.32-5-686/kernel/drivers/staging/hv/
cp drivers/staging/hv/hv_storvsc.ko /lib/modules/2.6.32-5-686/kernel/drivers/staging/hv/
cp drivers/staging/hv/hv_blkvsc.ko /lib/modules/2.6.32-5-686/kernel/drivers/staging/hv/
cp drivers/staging/hv/hv_netvsc.ko /lib/modules/2.6.32-5-686/kernel/drivers/staging/hv/
depmod
echo hv_vmbus>>/etc/modules
echo hv_storvsc>>/etc/modules
echo hv_blkvsc>>/etc/modules
echo hv_netvsc>>/etc/modules

the new ethernet interface will be eth1. eth0 is still the old one. Don’t forget to configure it in /etc/network/interfaces.

sorry, in the previous comment I didn’t see that the wget command was downloading the kernel from kernel.org.

So it is not “potentially harmful”, it is just “useless”.

Cheers.

Hello Gilles,

Thanks for your comments. I’ll try that soon.

Hello Dmitry,

I haven’t tried that on Debian 6 yet. You can try Gilles’s way. If it works for you, please leave a comment.

Thanks.

Yusuf.

Hi, all!
Thanks for comments :)
Well, I have try to follow Gilles’s post and make this steps:
1) wget -c http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.38.4.tar.bz2
2) unpack the kernel and “make menuconfig”
3) just “make”
4) cp drivers/staging/hv/*.ko /lib/modules/2.6.32-5-686/kernel/drivers/staging/hv/
5) depmod
6) cat /etc/modules
loop
hv_blkvsc
hv_netvsc
hv_storvsc
hv_timesource
hv_utils
hv_vmbus

Ok, try to reboot. System start quickly and what we have:
#lsmod | grep ‘hv_’
Nothing, hm, ok.
#cat /var/log/messages | grep ‘hv_’
hv_timesource: disagrees about version of symbol module_layout
hv_vmbus: disagrees about version of symbol module_layout

Well, the new modules version is from a different kernel version.
#uname -r
2.6.32-5-686

Hmm… WTF? :)

Hi Dimitry,

I think Gilles should reply your problem :)

Also Blake says it works on Debian 6. Maybe you miss something?

Hi, Yusuf!
I follow the Gilles’s manual step by step :) Well, I have no idea yet :(

Coincidentally I found this article and am following the same process (without any kernel development experience) and get the same warnings/errors. Let me know if you find a solution.

Hi!

Do you know how to enable dynamic memory on an Debian Squeeze Hyper-V Virtual Machine?

I enable that on the VM Settings, but it requires Guest OS Support.

Thank You!

Daniel Costa

1) wget -c http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.38.4.tar.bz2
2) unpack the kernel and “make menuconfig”
3) just “make”
4) cp drivers/staging/hv/*.ko /lib/modules/2.6.32-5-686/kernel/drivers/staging/hv/

Well, Differnet versions of the kernel in question here… You are downloading 2.6.38 and installing the drivers in 2.6.32, also different versions of GCC compared to the one the kernel was originally compiled with will stop you using Gilles suggestions – see /var/log/messages i.e. “Linux version 2.6.32-5-amd64 (Debian 2.6.32-39) (dannf@debian.org) (gcc version 4.3.5 (Debian 4.3.5-4)” gcc 4.3.5 isnt the current one – 4.4.5…. an old post i know but people are still finding this so i thought i’d add my 2c worth!

… good luck guys!

Hi Guys

I want to enable hyper-v support in debian-6.0.4 , the default kernel comes with newly installed is 2.6.32.5, can i build custom kernel by downloading the same kernel source of 2.6.32 or need to at least 2.6.36 or upper version ?, kindly suggest thanks

If you are running Debian 6.0 (Squeeze), You can use the Debian 7.0 (Wheezy) kernel from the Debian “backports” project – see http://backports-master.debian.org/Instructions/ – this is the Wheezy kernel which has been packaged to work on Squeeze, and includes the Hyper-V extensions. Works well for us…
