[Xen-users] suggest improvements in my doc to compile Xen from sources
Hi, I am writing a small doc for people new to Xen. to be able to compile Xen from sources on Ubuntu. Please suggest some improvements for this how to or mistakes that you can point out. There is a technique of virtualization known as Xen and a hypervisor known as Xen. Like you have Firefox,Open Office,VLC and other softwares on your computer similary there is a software known as Xen. Technically it is a hypervisor.Which runs in your computer and this is what will be able to help you to install Guest Operating Systems on your computer. The term Xen is often confusing to newbies since the technique of virtualization is also known as Xen and the hypervisor is also known as Xen. To be able to use Xen you need to have a system which has Linux installed. Install Xen on it. 1) Understand what is the difference between PVM and HVM. 2) Understand how to create guest operating system on Xen (hypervisor) This doc is for those people who want to compile the hypervisor Xen for example you might have ever used vlc media player on your Linux box. There you install it as yum install vlc or aptitude install vlc If you download vlc from videolan website and do some steps as ./configure make make install then this is what is known as compiling from sources. This doc will describe this procedure. So to begin with get a Linux computer. When I began I used a P4 with 256 MB RAM. Technicall Xen can run in this low configuration but you will save a lot of troubles if you use a machine with higher RAM. ====================================================================================== sudo apt-get install iproute bridge-utils gcc make gettext sudo apt-get install libcurl4-openssl-dev è openssl sudo apt-get install python-dev zlib1g-dev bcc libsdl-dev pciutils-dev è zlib First we will compile latest XEN Hypervisor from source. Go to http://www.xen.org/products/xen_source.html and download the latest XEN hypervisor from here.

Re: [Xen-users] suggest improvements in my doc to compile Xen from sources
Hi Tapas, all your idea is fine,I, for one, still use karmic koala + xen 3 from the repository + 2.6.26-2 amd64/xen kernel from debian. My configuration on my laptop is still fine though had some problems that i''m tired of (one for all, with this kernel and 3 giga of ram xorg work on the dom0, with 4 giga fails!) Best attempts i tried so far are the one at http://virtualusr.wordpress.com/ even if i''m still unsuccessful. I would suggest you to add to your document more and more details to the interactions with grub/grub2 I''ll try your howto in september, right after a fresh installation of lucid on a secondary usb hd.

PV_ops right now suck due memory hotplug problems. xen-linux is much better choice.
