A system for controlling, by a hypervisor, access to physical resources during execution of a virtual machine includes a physical disk and a hypervisor. The physical disk is provided by a computing device and stores at least a portion of a virtual disk. The hypervisor executes on the computing device. The hypervisor allocates, to the virtual disk, an amount of access to the physical disk. The hypervisor determines that a level of utilization of the physical disk has exceeded a threshold. The hypervisor limits, in response to the determination, access by the virtual disk to the physical disk.
