[bug#63527,v4,7/8] services: childhurd: Bump default qemu memory to 2048MB.
Commit Message
When booting with pci-arbiter and rumpdisk and using 1024MB of memory for
qemu, booting hangs, or seems to hang, at the end of the rumpdisk boot
messages. At least 1200MB is required, currently.
* gnu/services/virtualization.scm (<hurd-vm-configuration>)[memory-size]: Bump
to 2048.
* gnu/system/examples/bare-hurd.tmpl: Suggest using 2048 here too. Update
example `guix system image' and "qemu" command lines too.

Sounds a bit fishy. :-)
Does Debian resort to a similar workaround?

Yes, Debian has the same problem, the latest debian image
(https://cdimage.debian.org/cdimage/ports/latest/hurd-i386/debian-hurd-20220824.img)
hangs in an identical way.
See https://logs.guix.gnu.org/hurd/2023-05-18.log#091300
youpi seid "rumpdisk is very eaty, we need to fix that"
