You can adjust the host disk allocation for a virtual machine.

1

Click the Resources tab.

2

Select Disk in the Settings list.

3

In the Resource Allocation panel, select the virtual hard disk from the list.

4

Click in the Shares field. Use the drop-down menu to change the value to allocate a number of shares of its disk bandwidth to the virtual machine.

Shares is a value that represents the relative metric for controlling disk bandwidth to all virtual machines. The values Low, Normal, High, and Custom are compared to the sum of all shares of all virtual machines on the server and, on an ESX/ESXi host, the service console. Share allocation symbolic values can be used to configure their conversion into numeric values.
