Hi, I am a newbie to xen and I have a very basic understanding of xen and its architecture. This is my requirement: My Dom 0: Ubuntu Feisty Dom U: RHEL3 Now I have got my Dom 0 running. The problem is with Dom U. I''m just not sure how I should create a xen enabled RHEL3 image. I happen to find a lot of documentation to install other ubuntu flavours using debootstrap or to download images from jailtime.org where RHEL3''s image is not available But I couldn''t find any documentation to build a xen enabled image from scratch using the CDs... I would really appreciate if someone could help me out with this.

Xen 3.x doesn''t support PV linux 2.4 kernel which RHEL3 uses. You might be able to create HVM DomU though.

It does of course assume that you have a new-ish processor (such as an AMD Socket AM2/F processor). The whole point about a HVM domain is that it runs unmodified OS''s. -- Mats> > Regards, > > Fajar > > _______________________________________________ > 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

You have to do a bit of upgrade (i.e. to avoid QM_MODULES errors) and then it will work. Not fine, not production stable (IMHO) but it will work, and if it is a strict requirement as in my case you don''t have much more options. I''m running a SKC4 dom0 with 2cpu/2gig ram old xeon processor, non VT, supporting 4 domU whic are 3 SLC3 and 1 SLC4. I''ve done this with Scientific Linux CERN 3 domU over a SLC 4 dom0. SLC is basically RHEL so these info may apply also to your case. important: have a look at /dev/* permissions before saying it works :) howto: http://project-xen.web.cern.ch/project-xen/xen/howto_slcXen.html xen domU images: http://project-xen.web.cern.ch/project-xen/xen/img/img.xml installing kernel 2.6 on SLC3: http://linux.web.cern.ch/linux/scientific3/docs/kernel26.shtml ivan -- http://www.bio.dist.unige.it voice: +39 010 353 2789 fax: +39 010 353 2948 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
