From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

QEMU: How to increase VRAM allocation? (sh.itjust.works)

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?

Solution by lnxtx@feddit.nl qemu-system-x86_64 [...] -vga qxl -global qxl-vga.vram_size_mb=128 -global qxl-vga.ram_size_mb=128

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

It's an improvement, but 500MB+ would be perfect.

Replace the value 128 to 512. And try again :)

I was under the impression that QXL driver were capped at 256MB too, thanks.
