XenAccess Equivalent?

XenAccess Equivalent?

[Hajime Inoue]

I am trying to find a library equivalent to XenAccess for KVM.  It seems
that libvirt is trying to replace some of it, but doesn't have 
theintrospection capabilities that xenaccess does.  In particular, I 
would like to be able, in host userspace, to access the guest's memory. 
  Is such a capability possible within KVM?

Thanks,

This library scares me tremendously but it should be possible to port it 
to KVM.  The monitor provides an interface to read/write physical memory 
so that's probably the most natural place to interact.

Actually, something you can already do today is attach gdb to a QEMU 
instance and then load the guest kernel into gdb.  Once you've done 
that, you can access all of the guest's data structures.  This is 
precisely what XenAccess does except that it offers an API for doing it.
