[Xen-devel] Is there any mechanism in XEN can use to limit the memory bandwidth of each domain?

Hi, all:

ÂÂ Â Â ÂAs we all know, Xen can alloc different amount of memory to different VMs, but these VMs access memory by one shared memory bus, which means if one VM access the memory very frequently, the bandwidth of the memory shared by the other VM will decrease.

ÂÂ Â Â ÂSo I'm wondering is there any mechanism in XEN can reserve the limit bandwidth of the memory for different VMs?

ÂÂ Â Â ÂThanks!
