This I could fix.

Here I am lost. Suddenly all build attempts on all workers fail with
"unable to mount root fs". I am not sure, if this is limited to
tumbleweed, It has definitively nothing to do with the OS version or
other setup of the build hosts ("I did not do anything, I swear!" ;).
I had a look and tried to reproduce locally with
osc build --vm-type kvm openSUSE_Tumbleweed x86_64
and it just works here (on an up-to-date Tumbleweed laptop, will try on
15.3 later)
I suspected differences in the qemu-kvm command line, but the only
difference I could spot (apart from different filesystem paths) was
(with '-' the bad one from pmbs, '+' being the good one locally):
-rng-random,filename=/dev/random,id=rng0
+rng-random,filename=/dev/hwrng,id=rng0
...
--mem-prealloc
--mem-path /dev/hugetlbfs
...
--smp 1
+-smp 4
I also retried with "-j1" and "-smp 1" also worked fine.
OK, I retried on a 15.3 machine and it fails the same way as on PMBS.
The fun thing is: the rootfs can be mounted but for some reason it is
not deemed "usable_root" by dracut
debugged this and found, that "/sys" is missing.
And alas, the update of the "build" package from
* Fri Aug 20 2021 Adrian Schröter <adr...@suse.de>
Features:
...
- Also create the /sys dir when preinstalling (to satisfy dracut)
The commit in github is much older:
commit 207a4729849c055f12ff8592e927a3e3db236097
Author: Michael Schroeder <m...@suse.de>
Date: Wed Feb 24 11:31:48 2021 +0100
Also create the /sys dir when preinstalling
The background for this change is that dracut has a usable_root()
function that checks the existance of /proc, /sys, and /dev.

I did simply add the "mkdir -p $BUILD_ROOT/sys" to
/usr/lib/build/init_buildsystem on my 15.3 system and now everything
works locally.
Doing the same on your OBS server machine should do the trick as well
(the workers fetch the build code from the OBS server IIRC).
Or just update to the latest version of the build package :-)
Hope this helps,
Stefan
