KVM: To badly go where (almost) no man has gone before

In this overview I will try to follow the installation path to get LCME 8.10 into a virtual machine which uses PCI(-E) devices from the host. Normally the option to install on a dedicated computer is the best, but as I want to host several systems, including LCME, websites etc and the ease of testing out new stuff combined with the fact that I want to keep it as green as possible lead me to the conclusion that virtualization was the way to go. Over the last 2 years I've been building systems that have failed in doing what I wanted (XEN and KVM based), but with the latest state of soft- and hardware I'll hope I'll have a better change. The below is my queste for the wanted setup up, step by step.

Virtualization the way I want to do it can only be done with specific hardware/firmware which uses VT-d, a virtualization PCI Passthrough technique embedded in the bios.

Status is concept from step 4

So I will state my machine details first:

• Motherboard: ASUS P5E VM DO with bios 10.1
• CPU: Q6600
• 6 Gb DDR-2 Memory
• 1 onboard GbE Nic
• 1 PCI-E GbE Nic
• 1 Hauppauge PVR-150 (for the moment)

Step 1) Install Ubuntu 9.04 server AMD 64 (should be easy enough if you are able to get LMCE up and running :-) )

Step 2) Make the system current:

 sudo apt-get update
 sudo apt-get upgrade

Step 3) Add some management tools:

sudo wget http://prdownloads.sourceforge.net/webadmin/webmin_1.480_all.deb
sudo apt-get install libnet-ssleay-perl libauthen-pam-perl libio-pty-perl libmd5-perl
sudo dpkg -i webmin_1.480_all.deb
sudo apt-get install mc

I use webmin to give my server a fixed ip address and perform other administrative tasks. MC (Midnight Commander) is a nice tool to move files around the server.

Step 4) To be able to do remote monitoring of virtual machines, install virt-manager on your remote machine. If your are using Jaunty on your remote system, install ssh-askpass as per [[1]]

sudo apt-get install ssh-askpass

or use ssh keys

Step 5) Download the latest kernel from The Linux Kernel Archives [[2]] and unpack it into /usr/bin.

sudo wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.30.1.tar.bz2
sudo tar -jxvf linux-2.6.30.1.tar.bz2 -C /usr/bin/test

Step 6) Install dependencies for make menuconfig and configure the new kernel as explained in "How to assign devices with VT-d in KVM" [[3]]

sudo apt-get install gcc
sudo apt-get install ncurses*
sudo cd /usr/bin/linux-2.6.30.1
cp /boot/config-`uname -r` ./.config [[4]]
sudo make menuconfig

Step 7) After configuring the kernel we have to build it:

make 
make modules_install 
make install
