Add commands:-

# git checkout origigin/xen/stable -b xen/stable

Build with attached config :-

# make -j2 (or 4 -number of cores your CPU)
# make modules_install install

Create initrd-2.6.32.9.img for your OS.

Hi All,

To follow up this, after Installing Xen Hypervisor 3.4.2 successfully, I downloaded Linux 2.6.18 with Xen 3.4.x support source tarball, updated for Xen 3.4.2 from xen.org website and compiled and installed.

Later I changed my grub.conf file to boot from Xen.

#######################

root (hd0,0)

kernel /xen-3.4.2.gz

module /vmlinuz-2.6.18 ro root=dev/mapper/VolGroup-lv_root LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us rhgb quiet

module /initrd-2.6.18.8.img

#######################

After I reboot, I get the following messages.

################

Xenopf Intel processor model 44 or P6 family is not supported.

Initialization failed.

LOADING DOMAIN 0

Cannot load bzImage v2.04. v2.08 is required.

Panic on CPU 0

Could not set up DOM 0 Guest OS

Reboot in 5 sec

###############
What is wrong happening here?

THanks

Hi Boris,

I was following your steps and got stuck in the middle. Here is what I did...

Step 1 was sucessfull and Xen Hypervisor 3.4.2 is installed successfully.

Now while doing the step 2

STEP 2:

Install Libvirt

# yum install libvirt libvirt-python python-virtinst \
virt-manager virt-viewer (THIS WENT THROUGH SUCCESSFULLY)

PVOPS kernel 2.6.31.6 may be installed via Jeremy Fitzhardinge
Git Repository to support Xen 3.4.2 Dom0.

# git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-xen            (THIS WENT THROUGH SUCCESSFULLY)

# cd linux-2.6-xen
# make menuconfig ( setup Xen Dom0 support) (HOW TO SET UP THIS ?)
# make -j(x)(number_of_kernels) (I DID MAKE -J, WHAT SHOULD I GIVE HERE IN PLACE OF x. ??

BUT GAVE ME ERRORS. I DONT KNOW WHAT WRONG I AM DOING HERE. CAN YOU PLEASE HELP ME OUT IN THIS?)

I HAVE ATTACHED THE LOG FILE FOR YOUR REFERENCE. I AM USING FEDORA 12 MACHINE.

Thanks

BK

Now build pvops kernel.
Instructions bellow.
Reading PVOPS WIKI would help as well

Now I am able to do yum install kernel-xen xen.

I can see the xen Images sitting in /boot directory. Its xen-3.4.2.gz and xen.gz.

Is this what to be expected ?

I changed the grub.conf file to boot with Xen as below

title Fedora (2.6.31.9-174.fc12.x86_64)

       root(hd0,0)

       kernel /xen-3.4.2.gz



My question is I dont see vmlinuz-2.6-xen0 in /boot directory.

Do I need to add this line module /boot/vmlinuz-2.6-xen0 ??? But I dont see this file .When we do yum to insall xen, will it also install vmlinuz-2.6-xen0 also ??

Any idea what went wrong here??

thanks

BK
