Good Afternoon, According to the docs, Xen can allocate a specific amount of memory, and block and network I/O to a guest OS. And the guest can then request to change the allocation. I''m assuming that the hypervisor can limit the amount of network I/O a guest can use to prevent one guest from using up all of the available network I/O bandwidth. But can the hypervisor limit the memory bandwidth usage of a guest OS? What''s to stop one guest OS from saturating the memory bus?
