Update for Hyper-V to support 24 logical processor systems

Last week we released an update that enables Hyper-V to run on systems with 24 logical processors.  For example, a quad processor 6-core system.  The update also allows you to run up to 192 virtual machines on such a system.  A couple of things to note:

  • This update does not allow you to run more virtual machines on 16 logical processor or smaller systems.  Our supported limit is 8 virtual processors per logical processor, 8 times 24 is 192.
  • Unless you are running on a system with greater than 16 logical processors, there is no need to install this update.
  • Once you install the update on the parent partition, you will need to update the integration services inside the virtual machine.
