[David] I am worried about the effect of this on usage statistics, but still sounds very useful. [/David]
Currently EVENT_VM_UPGRADE is already handled in usage server, it records upgraded service offering into usage DB (though i cant find any codes that persist this eventType). Maybe this can be re-used for this feature if we only allow upgrade/downgrade between static service offerings. [Nitin] Mice - Great point. But, I think when the vm is scaled up, allocators need to be wise enough to figure out if it could be adjusted on the same host or need live migration. I think atleast XS and Vmware support live migration (across clusters as well) now so dynamic scaling would have less probability of failing, but this could be an expensive operation because migrating volumes across clusters will be resource intensive. [/Nitin] yeah sometimes migration is unavoidable, memory overprovisioning is somewhat irrelavant to this topic. Regards Mice
