Re: Hyper-V Guests: Compile Linux 2.6.32 on Ubuntu

I was lazy enough to copy paste commands into terminal window. After I executed
echo –e “hv_vmbus\nhv_storvsc\nhv_blkvsc\nhv_netvsc” >> /etc/initramfs-tools/modules
I got modules looking like:
–e “hv_vmbus\nhv_storvsc\nhv_blkvsc\nhv_netvsc”

Everything went fine but of course I got no hv modules in the end. It took me some time to figure out what went wrong.

Re: Hyper-V Guests: Compile Linux 2.6.32 on Ubuntu

Yes!
I got it!

BTW is your captcha case-sensitive? I missed 2 times. 3rd time is the charm as they say.

Re: Hyper-V Guests: Compile Linux 2.6.32 on Ubuntu

Art,

The command should append the following to /etc/initramfs-tools/modules

hv_vmbus
hv_storvsc
hv_blkvsc
hv_netvsc

Yes my captcha is case sensitive.

Hi Matt,
I came back here today and when I saw my 2 comments I realized that they look absolutely crazy. I was very emotional at the time and I forgot to thank you. I'm sorry about that and thank you for this post.

Hi Guys,

Does this solve the RDP mouse issue?

If not - is there any way to fix this?

Thanks

Re: Hyper-V Guests: Compile Linux 2.6.32 on Ubuntu

Ray,

Mouse integration is provided in a separate kernel module which is NOT included in the new kernel. For that you will want to refer to my other article:
blog.allanglesit.com/Blog/tabid/66/EntryId/26/Hyper-V-Guests-Mouse-Integration-on-Linux-VMs.aspx

I have not tested this on the new kernel version so it may or may not work.

You are very welcome.

Re: Hyper-V Guests: Compile Linux 2.6.32 on Ubuntu

Hello,
I really tank Matt for this article!
I´m a Linux beginner and I spend about two days working around this article because I hadn´t enough knowledge and Linux X HyperV its really new! At that moment my guest virtual Linux wasn´t able to accesses internet and to make things easier, I wrote a step-by-step. Please, correct me if I´m wrong in some way!
I installed build-essential and kernel-package from Ubuntu ISO CD using:
#apt-cdrom add
#apt-get install build-essential kernel-package

I couldn´t find and install ncurses-dev package even with Ubuntu 9.1 ISO CD, and to solve it, I downloaded from Ubuntu repository (us.archive.ubuntu.com/ubuntu/pool/main/n/ncurses/ncurses_5.5.orig.tar.gz ) to my PC and recorded it in a .ISO and installed it like this:
First I copied the .gz2 file from .ISO to Linux HD and uncompacted it. After that I executed:
#gunzip ncurses_5.5.orig.tar.gz
#tar –xf ncurses_5.5.orig.tar.gz
#./configure
#make install

Other problem was the Kernel download. I downloaded to my PC and recorded it in a .ISO and installed following the Matt instructions just changing apt-web step to copy from .ISO. After compile and install the new Kernel, I set up the network interface like this:
First I checked the network interface´s name using
#ifconfig –a
The interface´s name was seth0 and to set it up go to etc/network/ directory and:
#Pico interfaces
Insert this lines (if you have a DHCP server at your network):
auto seth0
iface seth0 inet dhcp
(to save change ctrl+o and to exit ctrl+x)
After that reboot, test the network connection using PING and have fun!

Note: First I tried to download and install a kernel already compiled and it didn´t work as Matt sad before.

My next fight will be with NAGIOS! Let´s see if will be easy or hard!

Thanks again Matt and sorry for my poor English!

It dose not solve, drivers writen just for MS linux ICS v1

Re: Hyper-V Guests: Compile Linux 2.6.32 on Ubuntu

and why so complex?

you need just add to repository
deb mirrors.kernel.org/ubuntu lucid main

download last kernel

add to # /etc/initramfs-tools/modules
hv_vmbus
hv_storvsc
hv_blkvsc
hv_netvsc

and run # update-initramfs

that's all you need? and dont't need to compile kernel

i've just checked hv versions between 2.6.32-9.13 from lucid main and 2.6.32.2 from kernel.org
it is edentical, no difference.

Build Description=Version 2.0
Vmbus supported version = 13

Re: Hyper-V Guests: Compile Linux 2.6.32 on Ubuntu

and from deb mirrors.kernel.org/ubuntu lucid main
you can download compiled kernel for ubuntu server, that very important for me

tests in my hardware

Ubuntu 9.10 amd64 2.6.32-9.13 Windows 2008 R2 Hyper-V

Re: Hyper-V Guests: Compile Linux 2.6.32 on Ubuntu

Everything compiled fine for me. However I see no difference in disk performanace. However the synthetic network card is now working.

Any ideas?

Vladimir Ganzha and "why so complex". Could you provide more detailed instructions on how to install for us newbies. Thanks

Re: Hyper-V Guests: Compile Linux 2.6.32 on Ubuntu

Hi!

Put up a small script that imitates the official Integration Services installer, but which works with the 2.6.31 (stock) kernel too. No need to recompile the kernel either. DL: sztupy.hu/static/hyper-v-ic-kernel-2.6.31.zip Unzip, run setup.pl and add the modules to auto-load.

.config for linux guest under Hyper-v

A bit unrelated but not so far from original topic:

Does anybody have a clean minimal working .config for a linux guest under Hyper-V 2008 r2?

If I understand correctly, any distro built with such a .config would run under Hyper-V right?

Re: Hyper-V Guests: rPath?

Hello all! I'm trying to use OpenFiler with the LIC drivers. I'm getting build errors similar to things I've seen online, but I'm way too much of a n00b to figure out what to do. The #openfiler channel on freenode is painfully silent, as well. I'm guessing they'd rather I explore this journey of "unguided discovery".

The package manager is conary, and I've gotten gcc updated. What can I do to build these drivers?

Thank you for any direction you can provide!

Re: Hyper-V Guests: Compile Linux 2.6.32 on Ubuntu

Thank you very much Matt, and all the comment contributors. This is very helpful. I managed to install 2.6.32 kernel on Ubuntu 9.10 running on Hyper-V R2. My virtual disk performance went from 60 MB/s to 117MB/s, which is very close to my physical SATA disk performance of 130MB/s.

2 things to mention:
1)
I also had the problem with the instruction above:
echo –e “hv_vmbus\nhv_storvsc\nhv_blkvsc\nhv_netvsc” >> /etc/initramfs-tools/modules

, which disregards the "\n" delimiter and puts this
–e “hv_vmbus\nhv_storvsc\nhv_blkvsc\nhv_netvsc”

in my /etc/initramfs-tools/modules file. I am a GUI guy, so I did a:
#sudo nautilus

I then used gedit to make the modules appear on four separate lines.

2) I also had problem with grub not booting up right. So a word of advice is to install grub (under Applications -> Ubuntu Software Center" before you reboot. Go in there and change something (i.e. make 2.6.32 your default. Hope this safe something some time.

Re: Hyper-V Guests: Compile Linux 2.6.32 on Ubuntu

Question: After the successful install, I now have 7GB of additional files on my .vhd. Can I delete the 6GB dir /usr/src/linux-2.6.32.1 dir, or if there is a way to clean it up?

Thanks.

Re: Hyper-V Guests: Compile Linux 2.6.32 on Ubuntu

Hi Matt,

Thanks for this write-up! Can you think of any potential issues with trying this on an Ubuntu Server 10.04 LTS 64-bit installation? As far as I know it uses 2.6.32 also.

Cheers.
