Description¶

xen host unreal6 has only 16GB phy memory, and dom0 occupies 3GB. at the same time, we have 8 workers assigned to this host. so sometime, we may not able to start a vm
if no enough memory.

However, from openQA failed job, I can't see clear error messages. https://openqa.suse.de/tests/15403428#step/bootloader_svirt/38

It only reports that virsh start failed: 1

When checking the autoinst log, I can get below error messages, but still not clear enough.

  error: internal error: libxenlight failed to create new domain 'openQA-SUT-3'

When I tried to check the logs from xen host, I can catch more clear error messages like below:

So, it could be great if openQA can report clear information when starting a VM fails.

Observation¶

openQA test in scenario sle-15-SP7-Online-x86_64-create_hdd_gnome@svirt-xen-hvm fails in
