Comment 1 Paolo Bonzini 2011-12-15 09:32:09 UTC 
I cannot reproduce this with neither a Fedora 16 guest, nor a RHEL6.1 guest.

I tested RHEL6.1 guest, after guest booting, if doesn't do anything in guest. 'info mem' still cann't show anything.  if try to run dd command in guest, info mem sometimes works.
Comment 3 Paolo Bonzini 2012-03-13 15:14:50 UTC 
"info mem" is not exposed to libvirt, closing.
