Hi, everybody. I have been reading about Xen, and really got interested in making it work here. So, Help me in some really simple questions. 1 - My host is a P4 512M. Wich OS should be the host one ? NetBSD or a Linux distro ? 2 - Where is a good step by step help for the answer above ? Thanks _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I found this the easiest way at 1st http://www.howtoforge.com/xen_3.0_ubuntu_dapper_drake Hope this works for you.

It is really nice to start in a list where people are really concerned in helping. Thanks for the answers and comments to my question. Yet related to the same topic, I ask you all about the most efficient OS to work as Host os. As you all told, Ubuntu seem to be the easiest way. But it is the most adequate? One more question: The host OS needs a graphic interface ? Or all of the guest OSeses will have their own ? The reason of that lst question is the aim of minimizing the host OS resources. Once more, thanks. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

But it is the most adequate?That probably depends quite a bit on what you actually want to do with your Dom0 - for example, what type of access are you planning for disks - disks directly attached to the machine itself, or "Network Attached Storage" - if the latter, does your choice work well with this solution? [I don''t know the answer to that for any OS, as I''m using only local disks in my test-setups - I work on the HVM part of the hypervisor, not disk-access at the Dom0 level!].> > One more question: The host OS needs a graphic interface ? Or all of > the guest OSeses will have their own ?Yes, no and maybe... It''s not necessary to have X running on the machine, but you _WILL_ need some way of using the guest of course. Some of my test-guests only use the (serial) console output, but if you for example want to use Windows as a guest, it''s much harder to get away with "simple" interfaces. PV guests being Linux and other variants of Unix will be perfectly happy to be accessed via SSH and similar. Finally, in my setup, I use SDL over SSH with X-windows forwarding - so the display of my Xen-guest is displayed on a different machine than where it runs - it works just fine. So I can run MS Windows on machine "svm" and view it on machine "devel" - I like that because I can have all my development windows visible at the same time as I look at what the guest is doing, rather than switching back and forth across the machines. -- Mats> > The reason of that lst question is the aim of minimizing the > host OS resources. > > Once more, thanks. > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users > > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Hi again folks. Just to answer two same questions: Petersson:> That probably depends quite a bit on what you actually want to do with > your Dom0Anuj Bhatt:> It depends on your specific needs.I want a system to practice conectivity among different OSes. There will be no production at all, just many tests that should normally require different computers, interconnected to each other. There I will combine Mandriva, OpenSuse, Debian, Slackware, FreeBSD, NetBSD and Windows (98/XP2k series), each one performing different services (email, proxy, firewalls, etc). I will often make many changes to each one of then, and to start a new set of tests, I will need a brand new installation of each OS. Like in VMWare (I think), all I will need to do is copy the file of a Virtual Computer over the modified one to have a whole new one again. My studies will need Internet access, for ocasionally updating some packages, thus I guess all of the host OS will need a connection to the real network interfaces. But I don''t want to keep using a free version of VMWare, since XEN seems to be farly more fancy and challenging. Dreams of a wannabe "bits polisher", if this make any sense... :) The sad point is that my computer is a poor and weak P4 512MRam, and not a Pacifica or a VT. So, I wish to have the lightest host OS I can for XEN, since it will make no work, but playing the DOM0 part in this "film". If it is possible that this host OS lacks any graphical interface, that should be better. At least, this is my guess. I am reading the links you all sent me, and I will try not to make obvious questions. But for now, I really need the kick-starting to it. Hope I can do it by myself afterwords.> Finally, in my setup, I use SDL over SSH with X-windows forwarding - so > the display of my Xen-guest is displayed on a different machine than > where it runs - it works just fine.

I should learn to do that also, seems really cool and functional. Need to learn Windows first :) But for now, I want this baked off my begginer''s oven. Once more, thanks for your help.

As long as you have plenty of diskspace, it works fine.>From what you describe, it doesn''t seem like you should have to worryabout "which Linux" - I''d pick one that you''re familiar with and try that. If it doesn''t seem to work, ask here, and you''ll probably get two types of answers: - Just change to XXX (where XXX is Fedora, SuSE or Debian) - You need to install package YYY. Very few distributions are "doomed" when it comes to running Xen inside them (on top, below or whatever you want to call it).> > But I don''t want to keep using a free version of VMWare, since XEN > seems to be farly more fancy and challenging.

At least, this is my guess.That pretty much precludes being able to run Windows on your Xen-machine, as you do need "HVM", i.e. AMD-V or VT to be able to run OS''s that you don''t have source-code for. Also, if you wish to run more than one or two guests, I would expect that you need more than 512MB of RAM, (unless you spend a lot of effort stripping each guest down to a minimum before you get "serious"). Dom0 itself needs at least 96-128MB - I run 256 "to be safe" (also useful when I decide to do "emacs vm-save-file" or "objdump -d xen-syms > blah; emacs blah" - those files can be a "a bit big"). Also, if your intention is to test for example "RedHat version X" in the form supplied by RedHat, you''ll want a machine with HVM, as for the para-virtual model, the guest-OS has to be a xenified kernel, which is different from what for example your customers (or "most people") would run on the machine. Of course, an option that already works on your existing machine is to use VMWare - as the VMWare solution uses a "binary translation" method of essentially stepping through the code and replacing bits of it with "traps" to the hypervisor when necessary. So you don''t need a "special" processor to run VMWare.> > I am reading the links you all sent me, and I will try not to make > obvious questions.

Need to learn Windows first :)It''s not difficult, you need to use ssh with the -X option (or add "ForwardX11=yes" in a file called ~/.ssh/config). So on "devel", you do "ssh -X svm", and then anything that uses X windows on SVM will appear on the "devel" machine. That includes the Xen HVM window from either SDL or VNC - and it''s got nothing to do with learning Windows in itself... ;-) -- Mats> > But for now, I want this baked off my begginer''s oven. > > Once more, thanks for your help. > > Glberto Martins > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users > > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
