opencoordination #102906: [saga][epic] Increased stability of tests with less "known failures", known incompletes handled automatically within openQA
coordination #102909: [epic] Prevent more incompletes already within os-autoinst or openQA
Improve incomplete output for qemu related problems, e.g. auto_review:"Failed to allocate KVM HPT.*Cannot allocate memory":retry instead of "can't open qmp"

Description
Observation¶
https://openqa.opensuse.org/tests/1355023 shows reason "backend died: can't open qmp at /usr/lib/os-autoinst/OpenQA/Qemu/Proc.pm line 448." so one needs to take a look into the logfile which shows:

where the latter is only visible in the log file.
Acceptance criteria¶
- AC1: The reason includes the content from the last qemu output
Suggestions¶
- For qemu related problems try to parse the (last) line that starts with "QEMU: " and put that into the reason instead of "can't open qmp"
