Taking hints from a blog on building xen 3.2 specifically I found http://www.cl.cam.ac.uk/research/srg/netos/xen/readmes/hg-cheatsheet.txt Unfortunately, I did not bookmark the initial page that linked to the mercurial cheatsheet above. It essentially said that the xen 3.2 stable source build was broken and that in order to get it to build correctly it recommended downloading the whole 'testing' repository source tree using the command; $ hg clone http://xenbits.xensource.com/xen-3.2-testing.hg I wondered where hg was (I knew it was the symbol for mercury) as I did not have that particular program installed. It turns out that the xen project uses mercurial as a revision control system and that program needed to be installed in order to clone the project source tree. Now I have cvs, subversion AND mercurial. Using; $ sudo apt-get install mercurial brought in mercurial along with python 2.5 and friends. I was then able to run the hg command and download the 'testing (3.2.1)' source tree. I thought I had all the tools necessary to build xen a week ago but, apparently not. The build is running now and I can relate the rest of the story if anyone is interested. I would also like to try 'make world' on the xen-3.2 directory to see if I just needed tools which were not spelled out in the 'README'. I've used up a lot of bandwidth (sorry!) at kernel.org getting linux 2.6.18 several times and still will need to resolve; 1. The kernel xen-3.2 uses, appears to be set at linux-2.6.18 and trying to use a more recent kernel version appears troublesome. 2. Building distribution packages are documented on RedHat, Ubuntu, and CentOS, but debian will require some study (and I don't know if I care about running xen from a .deb).

I suppose that might be a sort of rhetorical question, but downloading software into /usr/local, /opt/ and the like should be perfectly safe on a debian system. debian doesn't mess with those parts of the filesystem, and as long as the installed stuff doesn't mess with the non-local system directories, libraries, etc., there should be no conflicts. If the sources you're installing from *do* put things into system as opposed to local places, then you could probably look at that as polluting the machine.

More generally, is there a HOWTO or FAQ that would give me some pointers to getting Xen up and running? Thanks! Rick Hi Rick Sorry for any typos. There is a problem for newer Debian kernels (as in the etch distribution) and Xen. They just don't work and there is currently no patch to save the day. Ubuntu has Xen based recent kernels which apparently work well but I have not yet tried them. The Xen web site has 3 Xen options one of which I think is still free. Either one of these 3 options can be installed providing a DOM 0 basic virtualizing machine. Also, some of the other Linux distributions like SuSE have Xen based kernels. Xen based kernels are regular kernels but have the Xen application compiled into them making them the basis for hardware virtualization and thus called DOM 0 meaning the virtualization machine that redirects system calls from DOM U distributions. A DOM U distribution is virtualized meaning that during the time slice for a particular DOM U distribution it's system calls get re-routed to the DOM 0 computer resources (mostly hardware including CPU, memory, drives, LAN interface, etc.). DOM U distributions each have their own partition and are activated by the DOM 0 Xen application as a virtual machine.. There can be as many as 64 partitions in total including the partition for DOM 0. Most designers prefer to have the DOM 0 Xen system as a minimal distribution. The DOM 0 distribution can create virtual machines from it's own distribution so that you might have several virtual machines each doing one important thing instead of the conventional way where all these things get done on the one distribution. Of course, you can run other Linux distributions as DOM U installations. This is what makes Xen most efficient. Your fastest, safest, and best solution right now would be to get one of the 3 optional systems offered by the Xen developers. Apparently, they have a blog and I know they have a list. I have a download of the free Xen package on a CD which is now a year old and which I will be installing on a computer. I will install a large Debian distribution as well as smaller Debian distributions each in their own partition and use them as virtual machines. DOM 0 will be the free Xen package which took me a week to download and now I am trying to find it. The Xen documentation describes how the DOM 0 machine is made aware of the DOM U partitions with their respective distributions. BTW, you can now take a Windowz distribution like XP or more recent and run it as a DOM U virtual machine.That's neat if you have applications like I have that can only run on Windowz. But you have to buy a license from MS. Hope this information gets you going. There is one fellow on the debian-user list that has had a Linux Xen system running for about 2 years or more but that system would be running on an older kernel and he would have compiled the Xen application into the kernel and I think he used the AMD CPU. A number of people have tried to update their older Debian kernel with patches which automatically makes their system non operational. I think Debian really missed the importance of Xen and to get a Debian DOM 0 system from the etch distribution was not possible. Apparently there is a new distribution by what I hear on the list chatter. That distribution I am not aware of other than it is Debian 4.x distribution. Hopefully, if that is the case there may now be kernels available with the Xen application installed. Have a nice day and if you get Xen up and running please be kind enough to let the list know about your configuration and other issues as there have been many over the last few years that have wanted help and

Martin Thanks for your information further down from these comments. I did not snip out the information below my following comments as I thought the information to be useful not just to me but to others that may be aware of our dialog. As I remember, the package as I call it consists of 2 integrated parcels of code. One parcel of code is integrated into the kernel as a patch and the other as you mentioned is like a dependent parcel for managing the operations. But definitely, the kernel is altered and has attributes the un-patched kernel does not have. So one either applies the patch or one gets a binary that has already been patched. Sounds to me you obtained a kernel binary that was pre-patched for use with Xen. There is no way the ordinary kernel can become the core of an Xen system without the patch. However, Intel hardware changes associated with the CPU chip may change that -- I simply do not know. Also, I was talking about kernel versions higher than yours (up in the twenties where yours was 18) and 32 bit. But whether the CPU is 32 bit on 64bit machines could be a problem, I don't know. Also, the AMD was the only working CPU architecture available on Debian and I don't know why that was the case. Many people do not use AMD as their CPU architecture.

Thanks, Ted aptitude install xen-linx-image-2.6-xen-amd64 no i'm not joking, those with the hypervisor and ioemu and i was set, I had the 2 or 3 minor updates since etch release and all of those kernels worked fine. the dom0 doesn't have anything apart from the official etch repos http://packages.debian.org/etch/linux-image-2.6-xen-amd64 aptitude search ~ixen i A linux-image-2.6-xen-amd64 - Linux kernel 2.6 image on AMD64 i A linux-image-2.6.18-5-xen-amd64 - Linux 2.6.18 image on AMD64 i linux-image-xen-amd64 - Linux kernel image on AMD64 i A linux-modules-2.6.18-5-xen-amd6 - Linux 2.6.18 modules on AMD64 i xen-hypervisor-3.0.3-1-amd64- The Xen Hypervisor on AMD64 i xen-utils-3.0.3-1 - XEN administrative tools i A xen-utils-common- XEN administrative tools - common files First Box (2 cores/1 cpu): cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 39 model name : AMD Opteron(tm) Processor 146 stepping: 1 cpu MHz : 2009.290 cache size : 1024 KB fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu tsc msr pae mce cx8 apic mtrr mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext fxsr_opt lm 3dnowext 3dnow pni lahf_lm bogomips: 5024.69 TLB size: 1024 4K pages clflush size: 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: ts fid vid ttp Second Box (4 cores/2 cpus): $ cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 65 model name : Dual-Core AMD Opteron(tm) Processor 2212 HE stepping: 2 cpu MHz : 2000.070 cache size : 1024 KB physical id : 0 siblings: 1 core id : 0 cpu cores : 1 fpu : yes fpu_exception
Getting started with Xen -- Xen enabled kernel for Lenny?
I'm trying to get started with Xen. I've installed Lenny and a bunch of packages that looked interesting and mentioned Xen in their descriptions. But there does not seem to be a Xen enabled kernel available. Is Xen built-in to the Lenny kernels, or what? I plan to spend tonite with my feet up in the easy chair reading the documents in /usr/share/doc/Xen-docs-3.1/ . I hope they will be helpful, but they don't seem to mention Debian specifically. I've googled every which way, but everything I find is for Etch or Sarge and expects me to have a Xen enabled kernel. More generally, is there a HOWTO or FAQ that would give me some pointers to getting Xen up and running? Thanks! Rick -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Rick I don't know if you've been here: http://www.howtoforge.com/perfect_setup_xen3_debian, but, I too am trying to build a XEN enabled kernel using linux 2.6.23.9. This link looked straightforward and possible. I have not gotten to the point of patching the kernel for XEN. I was also trying to add current support for NFSv4 and GRSecurity so it's a bit jumbled right now (a lot of rejects). Building for a Pentium 4 3.2 GHz. Dell system. A search of debian-kernel did not return anything useful IMHO. Michael -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

There is a problem for newer Debian kernels (as in the etch distribution) and Xen. They just don't work and there is currently no patch to save the day. Ubuntu has Xen based recent kernels which apparently work well but I have not yet tried them. The Xen web site has 3 Xen options one of which I think is still free. Either one of these 3 options can be installed providing a DOM 0 basic virtualizing machine. Also, some of the other Linux distributions like SuSE have Xen based kernels. Xen based kernels are regular kernels but have the Xen application compiled into them making them the basis for hardware virtualization and thus called DOM 0 meaning the virtualization machine that redirects system calls from DOM U distributions. A DOM U distribution is virtualized meaning that during the time slice for a particular DOM U distribution it's system calls get re-routed to the DOM 0 computer resources (mostly hardware including CPU, memory, drives, LAN interface, etc.). DOM U distributions each have their own partition and are activated by the DOM 0 Xen application as a virtual machine.. There can be as many as 64 partitions in total including the partition for DOM 0. Most designers prefer to have the DOM 0 Xen system as a minimal distribution. The DOM 0 distribution can create virtual machines from it's own distribution so that you might have several virtual machines each doing one important thing instead of the conventional way where all these things get done on the one distribution. Of course, you can run other Linux distributions as DOM U installations. This is what makes Xen most efficient. Your fastest, safest, and best solution right now would be to get one of the 3 optional systems offered by the Xen developers. Apparently, they have a blog and I know they have a list. I have a download of the free Xen package on a CD which is now a year old and which I will be installing on a computer. I will install a large Debian distribution as well as smaller Debian distributions each in their own partition and use them as virtual machines. DOM 0 will be the free Xen package which took me a week to download and now I am trying to find it. The Xen documentation describes how the DOM 0 machine is made aware of the DOM U partitions with their respective distributions. BTW, you can now take a Windowz distribution like XP or more recent and run it as a DOM U virtual machine.That's neat if you have applications like I have that can only run on Windowz. But you have to buy a license from MS. Hope this information gets you going. There is one fellow on the debian-user list that has had a Linux Xen system running for about 2 years or more but that system would be running on an older kernel and he would have compiled the Xen application into the kernel and I think he used the AMD CPU. A number of people have tried to update their older Debian kernel with patches which automatically makes their system non operational. I think Debian really missed the importance of Xen and to get a Debian DOM 0 system from the etch distribution was not possible. Apparently there is a new distribution by what I hear on the list chatter. That distribution I am not aware of other than it is Debian 4.x distribution. Hopefully, if that is the case there may now be kernels available with the Xen application installed. Have a nice day and if you get Xen up and running please be kind enough to let the list know about your configuration and other issues as there have been many over the last few years that have wanted help and advice. I reiterate, your best chance of success is to run out of the Xen box as provided by the Xen developers. Thanks -- Ted -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
