I’m having trouble allocating more VRAM to my QEMU virtual machine. Currently, I’m using the following command to launch my VM:
qemu-system-x86_64 -enable-kvm -boot menu=on -drive file=QEMU -m 2G -cpu host -vga virtio
Can anyone help me figure out how to increase the VRAM allocation in QEMU?

Not sure, but maybe the QXL driver will help:
qemu-system-x86_64 [...] -vga qxl -global qxl-vga.vram_size_mb=128 -global qxl-vga.ram_size_mb=128

Vga is fixed iirc, the original frame buffer was tiny, the emulated one gives you 16mv
Cirrus logic gives you 16mb too iirc, then you can use other drivers that give you more,

If I’m reading correctly, there isn’t a modern GPU driver for QEMU that supports customizing VRAM?
