/dev/sda2 refers to the partition in QEMU disk that contains your

I've got only one partition in my image file:
=========================================================

I'd expect I should refer to it with /dev/sda1. However, when booting it
doesn't find it.
It's strange, since it finds /dev/sda, i.e. the entire disk:
=========================================================
[ 6.438693] sd 0:0:0:0: [sda] 188743680 512-byte logical blocks:

enabled, doesn't support DPO or FUA
=========================================================
However, it then complains that /dev/sda1 does not exists:
=========================================================

done.
Gave up waiting for root file system device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/sda1 does not exist. Dropping to a shell!
=========================================================
Same thing if I try with /dev/sda2 or anything.
Regards!
