Problem No space left on device

[Luis Souto Graña]

Hello, could you help me? I have tried to install several times GNU guix using QEMU, but I always end up with the following error: "No space left on device".

My latest attempt, step by step:

$ qemu-img create -f raw gnuguix.img 30G
$ qemu-img create -f raw swap.img 10G
$ qemu-system-i386 -hda gnuguix.img -hdb swap.img -m 2048 -net nic,model=e1000 -net user -vga std -usb -usbdevice disk:format=raw:gnuusbinstall07.raw -boot menu=on


# dhclient eth0
e1000 eth0 is up
# fdisk -l
Disk /dev/sda 32.2 GB
Disk /dev/sdb 10.7 GB
Disk /dev/sdc 786 MB
# mkfs.ext4 /dev/sda
# cd /mnt
# mkdir gnuguix
# mount /dev/sda /mnt/gnuguix
# mkswap /dev/sdb
# swapon /dev/sdb
# free -m

# deco start cow-store /mnt/gnuguix
service cow-store has been started
fuse: bad mount point '/.rw-store': No such file or directory
# cp /etc/configuration-template.scm /mnt/gnuguix/config.scm
# nano /mnt/gnuguix/config.scm

I changed only:  (bootloader (grub-configuration (device "/dev/sda")))

#guix system init /mnt/gnuguix/config.scm /mnt/gnuguix --no-substitutes

After 30 hours:
