I did the same thing using xen 3.2 latter. I retrieve some memory and create new guests. The sum of all domU's memory is greater than real memory. And, I saw something nice... when I return some memory to xen the guest see this and update the memory available to the SO, for example, If the guest has 1gb and I use commands like "free" or "top", I see 1gb. When I return 512M to xen, this commands show me an updated value of 512M of available memory. So... Does xen implement some kind of Hotplug Memory for paravirtualized guests? And thanks for the last paper... I got some ideas from there... Att.
