Please follow the below steps to configure the DMA controller in Guest OS
1) Right Click on My Computer and select Properties
2) Click on the Hardware tab and click the Device Manager button
3) Click on the plus control of the "IDE ATA/ATAPI Controllers" section
4) Select and Right click on the "Secondary IDE Controller", and select ‘Properties'
5) Click the ‘Advanced Settings' tab
6) My guess is that Device 0 (or Device 1 if you are using an IDE disk) Transfer Mode setting likely says "PIO Only"
7) Click on the Transfer Mode setting to "DMA if available" and click OK
8) Restart the virtual machine.
