Source: Microsoft-Windows-Hyper-V-Worker
Version: 6.0
Symbolic Name: MSVML_MM_PAGES_ALLOCATED_IN_REMOTE_NUMA_WARNING_SUMMARY
Message: RAM was successfully allocated, but a subset of the physical pages was allocated on a remote non-uniform memory architecture (NUMA) node. This configuration is not recommended because it will reduce performance.

Resolve

Resolve remote NUMA problem

If the Non-Uniform Memory Architecture (NUMA) ratio on your physical system is close to 1, you should not see a drop in the performance of your VM you should not have to worry. On the other hand, if you have a bad ratio and the performance is of the VM is poor, you need to:

  1. Ensure that the memory associated with the VM is not larger than the memory associated with the NUMA node
  2. Set the preferred/required NUMA settings for each VM. These settings are exposed via the following properties in the Msvm_VirtualSystemSettingsData object in the WMI model: NumaNodeList and NumaNodesAreRequired.

 

Verify

The virtual machine is able to start successfully.
