Hi there, I have a small question. With RHEL 5.0 and RHEL 4.5 Enterprise Server, the maximum of guests you can make is a total of 4. With the packages here: http://www.xensource.com/download/dl_31rhel5.html and this one: http://www.xensource.com/download/dl_31rhel4.html Is it posible with these packages to make more guests? I know with Advanced Server editions it''s always posible, but I don''t have the budget right now to buy the licence for that ;). Thanks for reading! Jim. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

The open source version of Xen is limited only be memory size limitations (if you have REALLY small guests, and using x86_32 version of Xen, there is a limit in the size of the XEN heap which gets you an "out of memory" at roughly 100 guests, but that can be modified if this is really limitng your usage - although it does require a Xen hypervisor recompile). The tar-balls that you''ve linked to above is the open-source version, so they are not restricted by any license restriction, just the "physical" limits that the system you run them on (and the Xen heap-size). -- Mats> > Thanks for reading! > > Jim. > > _______________________________________________ > 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

I''d be surprised if they''d support > 4 RHEL guests, unless you''ve paid for extra licenses. I''m not sure exactly how their licensing terms would handle this. Does RHEL actually limit the number of guests you can create, or is it just that they''ll only *support* up to 4 RHEL guests? i.e. could you maybe create arbitrary numbers of CentOS or Ubuntu guests?

It is merely a support issue. eg, if you''re running 5 Xen guests & you call support they''ll ask you to shutdown one of your guests. With the RHEL Advanced Platform there is no support limit on number of guests. In all cases the actual software is identical.
