I have Fedora core 4 i386 with kernel 2.6.11-1.1369_FC4. I have been trying for days to find the Linux patch for this kernel, but without luck. Has anybody tried it out? Where did he download it from?
Thanks

You may want to rephrase the question, cause I'm a little confused.

Are you looking for a patch to be able to run virtual servers, or to run your fedora installation as a virtual server? You question is slightly confusing.

Probably, i'm the really confused one. In general im a looking for a patch, in order to be able to run virtual servers. But i would be able to also run my fedora installation as a virtual server, the same way i will with other distros. Isn't that true?
I just started getting to know this "technology". So far i've only got in touch with http://linux-vserver.org/

first place I'd start looking is Andrew Mortons changelog for his kernel patches.
http://kernel.org/pub/linux/kernel/people/akpm/

It looks as if you aren't looking for virtual machine software, like vmware or plex86, which was my first thought when I read your post. Andrew's patches are experimental, but support lots of new functions, some of which you are probably looking for.

since you have a gentoo box, and then you can configure your kernel manually and look at each feature to see if you want to include it.

Thanks musicman_ace, you're right i don't look for vmware and relevant.
Are these patches also relevant to http://linux-vserver.org/ project?

From what I've read on that site, I can't find a specific patch that is required. Unfortunetly I'm not going to read all their documentation to find the answer. If they are just running chroot'd installations, no patch would be required. I think their software is a little more elligant that a chroot, but probably a recent stable release will work.

I don't know if everybody is confused or just me, but...

What I understand is that you want to try Fedora Core 4 with Xen virtualization, isn't it?

I haven't tried, it's in my list of things to do once my desktop stops overheating (It's gone three times for gurantee).

What you have to do is install the patched kernel and follow the official
Fedora XEN Quick start page

I find the quick start page too quick as it assumes that you already have the patched kernel.

You can find the patched kernel in your FC4 installations CDs (I forgot what CD it's on, I think it's in one of the SRMPs CDs). I am sure that you can install it through YUM.

Just type the following in a root console:
It will give you a list of kernels, from there you will identify the one with XEN. then type the following:

Modify your /boot/grub/grub.conf to add that kernel and follow the instructions on the Xen Quick start page.

Good luck

[EDIT] I'm sorry that I cannot give you the actual kernel name, but as I said before my Fedora desktop is not feeling well tonight.

I want to try this: http://linux-vserver.org/ and i have found many ways in which the words/phrase "virtual server" is used, which are irrelevant to this project/technology -unfortunately i haven't found any docs/resources somewhere else, which are relative to this project. In this project (http://linux-vserver.org/) , you can use multiple linux images (on top of your main/real linux os) in order to run any kind of server. Pros: you can restrict the resources, increase security, test new stuff, which won't harm/crash your real os, because they run on top of a virtual os.

I just read a more detailed descreption of the Xen project. It focuses at the same goals as http://linux-vserver.org/ project; isn't it?

Actually the goals that you wrote down in your previous post are closer to the XEN goals than to the http://linux-vserver.org/ goals and definetivelly different than those of the http://www.linuxvirtualserver.org/.

The main issue here is what is the 'virtual' adjective applied to
- http://linux-vserver.org/: Virtual Private Server. In this case these are not Virtual servers, but Servers that are Virtually private.
- http://www.linuxvirtualserver.org/ : A cluster of servers work virtually as if they were a single server.
- XEN virtualization : Hardware virtualization.

For what I understand, the vserver goal is to create independent runtime environments inside the same OS. This is, Compartimentalize the runtime so you can have a chinese wall between 'Virtual Private Servers'. Each server works 'virtually' as if it was in its own box.

Some uses can be:
- Having a production and test environment in the same box.
- An ISP Running Servers for different clients on the same box
- An IT department assigning resource quotas for different processes.

The Virtual Server Goal is to have a high availability, highly scalability server where one HW server can go down or be removed and the cluster still works or where you can add new HW servers and increase performance. This is: Multiple Servers work as if they were virtually only one.

The XEN project goal is to enable running multiple OSs inside Linux. This is done by 'virtualizing the hardware'.

Hardware Virtualization: The OS does not talk directly to the hardware. It talks to the XEN virtualization engine that in turn talks to the hardware. So, for example, the virtualization engine could 'fake' a SCSI interface even if the real harware does not have SCSI.

Based on your posts I would say that the XEN project is what you want to look at. Any way, I think that with this little introduction you'll make up your mind on what you really need.
