I guess no other option than this? This is qemu from Fedora 34. The Fedora is running kernel 5.12.15-300.fc34.x86_64. The system is a VM running on top of Proxmox 6.4-13 with Debian buster, on top of AMD EPYC 7502P, and kernel Linux 5.4.124-1-pve #1 SMP PVE 5.4.124-2 (Tue, 20 Jul 2021 21:43:44 +0200). $ qemu-system-x86_64 --version QEMU emulator version 5.2.0 (qemu-5.2.0-8.fc34) Copyright (c) 2003-2020 Fabrice Bellard and the QEMU Project developers $ No other qemu options. I belive now this is a bug in the kvm and nested virtualisation. With no --enable-kvm (using software emulation), the installation proceed fine with 512 and 1024 MB. I also now tested it on non-virtualized Debian testing, and it works fine with kvm and 512MB. It even works okish with 360 MB (no network cards detected tho then for some reasons). >> Select "Install" (text installer, not graphical one). > I.e. the second boot option? (the 64bit variant) Correct. Second boot option, the 64-bit variant. > Select defaults (or other) for language, location and keyboard. > So just pressing enter to select everything by default?

Correct. But, now I was able to trigger the hang even ealier, just after kernel boot. As I said above, I belive the issue is qemu kvm and nested virtualisation actually, not debian installer. > I'm not getting such a problem (and 1024M is really plently to just load > components, it's partman that needs quite more, notably with crypto > enabled). > At worse, note from > https://www.debian.org/releases/bullseye//amd64/ch02s05.en.html > that you can force higher lowmem options, but 1024M should really be way > enough. Ack. Please close. (Network card detection failure when running with 360MB should be addressed separately. It looks like /lib/modules/5.10.0-8-amd64/kernel/drivers/net/ethernet has only one driver present - cnci.ko , not sure how to load others). Regards, Witold
