Description

We were bothered by this for a long time and it's still present: Hyper-V 2012 R2 serial console leaks data, usually it's the 16th character on a line.

In https://openqa.suse.de/tests/2030033#step/rsync/17 openQA expected SCRIPT_FINISHEDEcM1i but got SCRIPT_FINISHEDcM1i, note the missing E, a 16th character. This is a Hyper-V product issue and I don't know what we can do about it apart from trimming our magic strings to be shorter than 16 characters. I did this when Hyper-V 2012 R2 was our primary platform, but it is not anymore and Hyper-V 2016 has it fixed. This should not affect openQA groups outside of "Virtualisation".

This ticket mostly serves as a "wailing wall" for the purpose of openQA reviews and I expect it to be kept for the time we support Hyper-V 2012 R2.

@michalnowak, About this failure test, proxyscc_upgrade_sles12sp4_hyperv@svirt-hyperv2012r2, is this one the case that from automation we can do nothing to avoid the length limit on serial console?

@xlai: Both of them are the "unstable serial console on Hyper-V 2012 R2" problem.

It's easy to miss it but have a look the first one: "release-notes-sles" is expected, but "release-notes-ses" was received, l - the 16th character - is missing. For the latter one: "SCRIPT_FINISHED708tO-0-" is expected, but "SCRIPT_FINISHED08tO-0-" received, 7 - the 16th character - is missing.

What we can do is to trim magic codes to under 16 characters, but approach gets problematic for wait_serial() matched as they are expected to be longer than 16 characters. In such cases I plan to remove the test module from Hyper-V 2012 R2 runs.

Status changed from New to Blocked
Assignee deleted (~~michalnowak~~)
Difficulty set to hard

With current design of openQA which relies on serial console to be 100% stable, I - nor anyone else besides Microsoft - can do much in here. It's fixed from Hyper-V 2016 on, so just be patient and wait for 10/10/2023 (https://support.microsoft.com/en-us/lifecycle/search/1163).
