include vmm.inc mov ebx, VM ; VM handle VMMcall Resume_VM jc not_resumed ; carry flag set if virtual machine not resumed |
The Resume_VM service resumes the execution of a virtual machine previously suspended by the Suspend_VM service.
VM
Specifies a handle identifying the virtual machine to resume.
The carry flag is clear if the suspend count is zero, and the virtual machine is in the ready-processes queue. The carry flag is clear to indicate an error.
This service decrements the suspend count, and places the virtual machine in the ready-processes queue if the new count is zero. The system carries out a task switch to the resumed virtual machine if the virtual machine has a higher priority than the current virtual machine.
An error can occur if a virtual device cannot lock the memory handles for the specified virtual machine. The system notifies every virtual device of the request to resume a virtual machine, and any virtual device can deny the request. In such cases, this service returns with the carry flag set and the virtual machine remains suspended with a suspend count of 1.
