Error message when you try to start a Hyper-V virtual machine on a Windows Server 2008-based or Windows Vista-based computer that uses the NUMA architecture: "An error occurred while attempting to change the state of virtual machine VMNAME"
You are running a Windows Server 2008-based or a
Windows Vista-based computer that uses the non-uniform
memory access (NUMA) architecture. When you try to start a Hyper-V virtual
machine, the operation may fail because of a memory allocation issue. Additionally, you may receive the following error message:
An error occurred while attempting to change the state of virtual machine VMNAME.
'VMNAME' failed to initialize.
Unable to allocate 1024* MB of RAM: Insufficient system resources exist to complete the requested service. (0x800705AA)
*number will vary based on the amount of RAM assigned to the VM
This issue occurs even when there is
sufficient memory available.

For all supported Itanium-based versions of Windows Server 2008
The traditional model for multiprocessor support is
symmetric multiprocessor (SMP). In this model, each processor has equal access
to memory and I/O. As more processors are added, the processor bus becomes a
limitation for system performance.
System designers now use
non-uniform memory access (NUMA) to increase processor speed without increasing
the load on the processor bus.
