RE: Max memory on VM (debian bullseye)

[Wilm Boerhout]

(Bangs forehead to wall). I have been working too long with Raspberry Pi's with 
64 bit Debian. I never noticed that the laptop runs a 32-bit version of Debian 
now.

Back to the drawing board.

Thanks for the time you saved me!

Wilm

qemu-system-i386 is the binary for 32-bit QEMU x86 targets. There is always 
going to be a restriction on the amount of memory it can use, because it's 
32-bit. If you want as much as 12GB of RAM, don't you want qemu-system-x86_64 
(and probably also a 64-bit guest) ?
