Spring 2007 Vmware and Linux kernel COMS W4118 Columbia University

Spring 2007 Login to your assigned CLIC machine  Find your vmware account from the file “Vmware account assignment” in coursework shared files folder. Example: primary: os140 : zc2109 backup: os141 : zc2109

Spring 2007 Login to your assigned CLIC machine  According to your account, find your assigned CLIC machines from the file “Vmware machines in CLIC” in coursework shared files folder. Example: Machines VM1 VM2 VM3 VM4 VM5 lisbon.clic.cs.columbia.edu

Spring 2007 Login to your assigned CLIC machine  Login to your assigned CLIC machine with the command ssh – X yourmachine.clic.cs.columbia.edu or ssh – Y yourmachine.clic.cs.columbia.edu

Spring 2007 Prepare your vmware  After logging in to your assigned machine, create a folder named “.vmware” in your home directory by command: mkdir.vmware  Copy the license to your “.vmware” directory cp ~w4118/vmware/license.ws.5.0.vmware/

Spring 2007 Get Linux kernel source code  Copy the Linux kernel source code to a temporary location, like the current work directory cp ~w4118/vmware/linux tar.bz2./  Copy the kernel compilation configure to a temporary location cp ~w4118/vmware/config /

Spring 2007 Start your vmware  From your designated machine, run vmware vmware  Load the vm from your assigned directory. File -> open -> filesystem -> /vmware[x] -> linux.vmx  Select power on, start your linux in vmware User: root Pwd: osw4118

Spring 2007 Vmware IP address  Get your vmware IP address From inside the vm, type command "ifconfig" to get the IP If you don't see an IP like xxx type "dhclient"

Spring 2007 Copy file into vmware  Copy linux kernel source code into your vmware From the host system, your assigned CLIC machine scp linux tar.bz2  Copy linux configure file into vmware scp config :

Spring 2007 Compile the kernel Inside your vmware  Untar the source: tar xvjf linux tar.bz2  Copy config into the folder linux as ".config" cp config linux /  Make linked copy of the source code dir: cp -al linux / linux pudding

Spring 2007 Compile your kernel  Create configuration for your kernel compilation From inside linux pudding, type command make oldconfig  Compile the kernel 1. make 2. make modules 3. make modules_install Now verify that /lib/modules/ was created

Spring 2007 Make an entry for your kernel  Type command depmod –ae  Create initial image for preload modules mkinitrd /boot/initrd img Now verify that /boot/initrd img was created

Spring 2007 Make an entry for your kernel  cp linux pudding/arch/i386/boot/ bzImage /boot/vmlinuz.hmwk1  Modify grub loader (/boot/grub/grub.conf), add entry: title HW1 Kernel root (hd0,0) kernel /vmlinuz.hmwk1 ro root=/dev/VolGroup00/LogVol00 initrd /initrd img

Spring 2007 Start your kernel Reboot and Start your new kernel
