VMDirect Path
I/O behaves
abnormally on
AMD systems
configured with
more than 256 GB
of memory.
On AMD systems
configured with more
than 256 GB of memory,
the VMDirect Path I/O
feature fails. Such
systems running virtual
machines (VM)
configured with a pass-
through device do not
boot.
For example, a system
running Microsoft
Windows 2003 64-bit
Standard Edition
displays a Blue Screen
immediately after you
install the driver for the
BCM 57711/BCM57710
card attached to the VM
as a pass-through
device.
This issue is due to the
limitation of the
module AMDIommu in
ESXi 4.x. AMDIommu
fails to create the
required heap during its
initialization.
AMDIommu-related
Heap error messages are
logged in the vmkernel.
This is resolved in
ESX/ESXi 4.1 Update 2.
