Starting Hyper-V with Limited Memory Solution

I've been running Hadoop in Hyper-V, yet my laptop has limited memory.  When running Hyper-V with limited memory, it becomes slow using 3 to 4 gigs of memory, when it requires 8 or more.  So here's a fix to get it running faster:


It will require a change to the registry: 
  1. Start Registry Editor.
  2. Locate the following registry subkey:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization
  3. Right-click the Virtualization folder, point to New, and then click DWORD Value.
  4. Type MemoryReserve, and then press Enter.
  5. Double-click MemoryReserve, enter 2048 in the Value data box, select the Decimal option, and then click OK.
  6. Close Registry Editor.

Add new node:

Reboot and start Hyper-V.
