We may be able to use such a feature with dom0 pv_ops of upstreams. e.g. http://lkml.indiana.edu/hypermail/linux/kernel/0904.2/01317.html dm-ioband has rpm package of RHEL/CentOS, so you can use dm-ioband for xen. http://lists.xensource.com/archives/html/xen-devel/2009-04/msg00116.html If you are interested in dm-ioband, please comment to Ryo. He would want feedbacks from many users.
