Implementations describe hibernating virtual machines (VMs). In one implementation, a method includes receiving, by a first virtual processor of a VM executed by a processing device, an instruction from a sleep-handling module of the VM to invoke a sleep function of a hypervisor executed by the processing device to manage the VM, transmitting, by the first virtual processor of the VM, a request to the hypervisor to put the VM to sleep, wherein the hypervisor, in response to the request, to stop the first virtual processor subsequent to stopping a second virtual processor of the VM, and initiating execution on the first virtual processor and on the second virtual processor responsive to the hypervisor re-starting the first and second virtual processors in response to a wake event.
