Description

Observation¶

The job http://openqa-3.wicked.suse.de/tests/80283#step/before_test/23 show a eth0: IPv4 duplicate address 10.0.2.11 detected (in use by 52:54:00:12:00:56)! message
The mac 52:54:00:12:00:56 belongs to http://openqa-3.wicked.suse.de/admin/workers/86 which runs the job http://openqa-3.wicked.suse.de/tests/80207 during that time.

The job 80207 is a multi machine job and the parent is http://openqa-3.wicked.suse.de/tests/80206, which start at 2022-03-29T09:27:13.195681+02:00 and end at 2022-03-29T10:04:05.167885+02:00, while job 80207 ends at [2022-03-29T10:06:21.469947+02:00].

The failing job show the qemu command at: [2022-03-29T10:04:26.913030+02:00] [debug] starting: /usr/bin/qemu-system-x86_64 -vga cirrus -only-migratable..., thus
it start a qemu instance with the same VLAN which is still used by job 80207.

Simple reproducer, create two parallel boot jobs
