selsta, here is a log.

I'm trying now with -j3.

<BigmenPixel[m]> "I'm trying now with -j3." <- Or it can't help, or it doesn't work (?)... (full message at <libera.ems.host/_matrix/media/v3/do…e5b2f18f958c85f7059f0001b9f3f42313f>)

hmm, I'm not familiar with qemu, can it emulate multiple cores?#

or are you running -j3 on a single core "vm" now?

It can emulate multiple cores. If using virt manager you can set more/less cores for the VM. Default is 2 cores, atleast when configured on Ubuntu

QEMU must support emulating, but it seems, in the image there is no option for this...

* support emulating multiple cores, but

Even if it builds for a very long time, but I would like to increase the maximum amount of building time.
