We control the following properties of the devices in question:
'virtio-gpu'
virgl=<bool> - on/off (default: true)
'qxl'
ram_size=<uint32> - (default: 67108864)
vram_size=<uint64> - (default: 67108864)
vram64_size_mb=<uint32> - (default: 4294967295)
vgamem_mb=<uint32> - (default: 16)
max_outputs=<uint16> - (default: 0)
'vhost-user-gpu'
max_outputs=<uint32> - (default: 1)
chardev=<string>
'VGA'
vgamem_mb=<uint32> - (default: 16)
'bochs-display'
vgamem=<size> - (default: 16777216)
common for all devices:
xres=<uint32> - (default: 0)
yres=<uint32> - (default: 0)
The only noticable change is using memory size in bytes for
'bochs-display' instead of kibibytes.
