Re: [Xen-devel] Interfering with memory accesses

[Bilal Bakht Ahmad <tringingly@xxxxxxxxx>]

As far as I understand, libvmi only lets us access memory based on virtual and physical addresses. I want to interfere with a memory access within Xen, say re translate a certain range of addresses and such.Â

More so, I'd like to confirm if ANY part of the address translation happens within the hypervisor, or does it all take place through page tables?Â

Have you looked at http://libvmi.com/ ?
