[Xen-users] Re: Managing multiple Dom0''s (Jonathan D. Proulx)

I''m loking at a potential setup of 16 or so physical systems with perhaps 64 or so virtual systems (DomU''s I suppose Dom0 is also a virtual system if I understand thing correctly, but that''s no twhat I mean here). It seems to me that making heavy use of migration for load balancing would make it difficult to know where a given DomU was running at any given time and make it difficult to know which DomU''s if any should be started on boot up. My current test setup is running 3.0.1 on Debian Stable. I have two physical systems with a shared F/C disk array using CLVM, which holds the vbd''s for teh DomU''s and a GFS filesystem shared between the two Dom0''s . I''m currently considering witing a wrapper for "xm" that uses a database to store DomU options and last run locations, but I''m hoping someone aleady has somehting... -Jon ------------------------------ What about "heartbeat-2" usage? Defining one "service" per domU, it will be simple to manage a whole bunch of them... Sure you cannot "live-migrate it", but using "xm save"/"xm restore" as stop/start actions for the domU''s "services" it should not be a looooooooooooooong wait :) Best regards Ferdinando _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
