[Xen-users] migrating between different processors (intel/amd)
We are looking at buying an additional server. Our current server is AMD based (low end - 1210 I think). The new one we have in mind can either be Intel (quad core) or AMD (dual core). The Intel CPU with the additional cores is probably better for performance (but more expensive obviously), while the AMD is more compatible with what we have (1214) I understand that migration between vastly different CPU''s is not really possible unless you disable the features on the vcpu to the lowest common denominator (and even then?), but what about just shutting down the domain and then starting it on the other server? Does Windows get upset because it has a different CPU and suddenly demands to be reactivated? Any comments or suggestions?

We use Unix/Linux mostly, with some Windows 2003 servers here and there. For Windows 2003, Volume Licensing should be able to take care of activation problem http://www.microsoft.com/windowsserver2003/techinfo/overview/activation.mspx "If your organization licenses Windows Server 2003 R2 through one of the Microsoft volume licensing agreement programs, such as Open License, Select License, or Enterprise Agreement, you are not required to activate those licenses." Since Open License requires only 5 license minimum purchase, it should be feasible for most purposes. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

RE: [Xen-users] migrating between different processors (intel/amd)
In the past, those 5 licenses could include client access licenses, so you could buy one server, add 5 client access licenses (for much less than 4 more server licenses / 4 office licenses / 4 xp licenses), and the cost was even more reasonable. That may still be the case regarding the licensing, however, with Vista/2008 and higher, activation may still be required (albeit different) for the software; I am not sure since I am only running XP and 2003. Another option may be the MSDN (?) subscription, I haven''t ever actually had one, but I think it includes copies of a lot of software with licenses that are still good after the subscription expires.
