The Debian official live CD image will probably do fine: https://www.debian.org/CD/live/ I don't know if QEMU is installed in it by default but if it isn't you should be able to install it from the network once you've booted the liveCD on your host. thanks -- PMM

Is there a Qemu/KVM live CD or such with the minimum 64-bit Debian set to support it? -Original Message- From: Peter Maydell Sent: Wednesday, April 19, 2023 6:30 PM To: Wilm Boerhout Cc: Qemu-discuss ; Narcis Garcia Subject: Re: Max memory on VM (debian bullseye) On Wed, 19 Apr 2023 at 17:27, Wilm Boerhout wrote: > (Bangs forehead to wall).

Yeah, if your *host* is running a 32-bit kernel I would definitely suggest switching that to 64-bit if you can :-) -- PMM

(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!

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) ? thanks -- PMM

RE: Max memory on VM (debian bullseye)
Thank you Narcis for your attention. Pc.ram is in the error message. And the difference between GB and GiB is not the issue. I tried binging memory down from 12 GB, and only when it was 1 GB, it would start the VM. Is there a restriction somewhere that I am not aware of?
