Subject: Cuirass remote worker is stuck building with 1 core
Date: Mon, 09 Oct 2023 09:14:25 +0800 [thread overview]
Message-ID: <c85eeaad7cb0c2698e5b1e6edd6f3df6eadb94c7.camel@yahoo.com> (raw)
In-Reply-To: c85eeaad7cb0c2698e5b1e6edd6f3df6eadb94c7.camel.ref@yahoo.com
I noticed that the Cuirass remote worker in my channel-building VM only builds things with 1 core, despite me having configured Guix to use multiple cores per build.
# Reproduction instructions
On a multi-core QEMU VM running Guix System with a Cuirass setup, run the following command:
```
cuirass remote-worker -w 1
```
This will result in the message "starting 1 workers (parallelism: 1 cores)".
# Expected output
The remote worker tries to build with the number of cores specified in guix-daemon's --cores. That, or $(nproc).
It should be noted that my bare-metal foreign distro install correctly selects $(nproc)-core parallelism. However, I have created multiple QEMU VMs running Guix System, and they all reproduce this bug.
