A mechanism for flow control-based virtual machine (VM) request queuing is disclosed. A method of the invention includes implementing a pass-through mode for handling of one or more requests sent to a hypervisor by a virtual machine (VM) managed by the hypervisor, determining that a number of outstanding requests associated with the VM has exceeded a first threshold, implementing a queued mode for handling the one or more requests sent to the hypervisor from the VM, determining that a number of outstanding requests associated with the VM has fallen below a second threshold, implementing the pass-through mode for handling the one or more requests sent to the hypervisor from the VM, and repeating the implementing and determining as long as the VM continues to send requests to the hypervisor.
