Device migration method, electronic device, and storage medium

A non-transitory computer readable storage medium, on which a computer program is stored, wherein the computer program, when executed by a processor, causes the processor to implement a device migration method, wherein the method comprises:

• transmitting, by a first virtual machine, a request message requesting use of a target device to a second virtual machine;
• comparing a first priority for the first virtual machine to use the target device and a second priority for the second virtual machine to use the target device in a case where the second virtual machine is in a pass-through connection with the target device;
• in response to the first priority being higher than the second priority, releasing first pass-through binding between the second virtual machine and the target device;
• and
• sending a migration message to the first virtual machine, to instruct the first virtual machine to perform a second pass-through binding to the target device.

An electronic device, wherein the electronic device comprises:

• a processor;
• and
• a memory, configured to store instructions executable by the processor, wherein
• the processor is configured to read the executable instructions from the memory, and execute the instructions to implement a device migration method, wherein the method comprises:
• transmitting, by a first virtual machine, a request message requesting use of a target device to a second virtual machine;
• comparing a first priority for the first virtual machine to use the target device and a second priority for the second virtual machine to use the target device in a case where the second virtual machine is in a pass-through connection with the target device;
• in response to the first priority being higher than the second priority, releasing first pass-through binding between the second virtual machine and the target device;
• and
• sending a migration message to the first virtual machine, to instruct the first virtual machine to perform a second pass-through binding to the target device.
