The French midfielder only joined the Russian outfit last season but a deal has been agreed that will see him join the Nerazzurri on loan for the 2014-15 campaign, with the option of a permanent switch next summer.
M'Vila has already undergone a medical in Milan but is now just awaiting the return of official documentation from Rubin to complete the move and insisted that there is no chance of him changing his mind or being tempted by 11th-hour offers from elsewhere.
"I only want Inter," the 24-year-old told Sky Sport Italia. "We will not leave Milan until we get the okay from Rubin.
"The medical visit went very well. We're only missing the okay."
M'Vila, who has 22 France caps to his name, joined Rubin from Stade Rennais for a reported £9.5 million.
