Technologies are generally described for systems and methods for reconfiguring a programmable circuit. An accelerator reconfiguration device may detect a trigger. The trigger may indicate that a command has been sent to a processor to switch from execution of a first virtual machine to a second virtual machine. In response to detecting the trigger, the reconfiguration device may identify a programmable circuit and program for the programmable circuit associated with the second virtual machine. The reconfiguration device may further generate a write command to write the program to the programmable circuit.
