action #95845

Updated by mkittler over 3 years ago

### observation 
 The fullstack test of os-autoinst fails under Tumbleweed because `eth0` (within the SUT) does not get an IP address assigned automatically anymore. Likely a change within QEMU causes this. 

 As a workaround the following PR has been merged: https://github.com/os-autoinst/os-autoinst/pull/1728/files 
 That means assigning an IP manually works and to reproduce the issue via os-autoinst's fullstack test one needs to revert 3cd3e5fe076ad4c1ee55ace70eade03d1f1f9bc8. 

 The problem is not limited to the TinyCore system, it also happens with openSUSE. E.g. when cloning a test with the `online_repos` module (like https://openqa.opensuse.org/tests/1849850) it becomes quite apparent that the IP address is not assigned: ![no IP](online-repos.png) 

 (The referenced test does *not* fail on the production instance because on production we're using Leap which doesn't seem to be affected.) 

 ### suggestions 
 * Check for changes within Tumbleweed's QEMU package 
 * Check for changes of the QEMU invocation produced by os-autoinst 
 * Likely a DHCP problem (with the DHCP server QEMU is supposed to provide?) 
 * Read https://wiki.qemu.org/Documentation/Networking
