Keir,
If I assign 1G memory for native, 'cat /proc/meminfo' shows the MemTotal is
1034672 KB, while 'cat /proc/meminfo' shows the MemTotal is 1033800 KB if
assigning 1G memory for hvm guest.

Best regards,
Fan

If you run 'cat /proc/meminfo' on native and on HVM, do the MemTotal figures
match up? If so, this must be an issue within the guest -- it would indicate
that we are providing the guest with the same amount of memory as was
available to it when running on native.
