There is a way to fix it.
You can modify x86-legacy.devs,as follows:
VGA = Hw.Device
{
hid = "PNP0900";
Res.io(0x3b0, 0x3bf); -- MDA
Res.io(0x3c0, 0x3df); -- EGA/VGA
Res.io(0x1ce, 0x1d0); -- Vbox
Res.io(0x402, 0x402); -- QEMU Debug Port
Res.mmio(0xa0000, 0xbffff); --Here lost a parameters. Changed to Res.mmio(0xa0000, 0xbffff,0xc000);
},
