Summary : Xen Virtualization: Libraries
Description :
Xen is a virtual machine monitor for x86 that supports execution of
multiple guest operating systems with unprecedented levels of
performance and resource isolation.
This package contains the libraries used to interact with the Xen
virtual machine monitor.
In addition to this package you need to install xen and xen-tools
to use Xen.
https://openqa.suse.de/tests/15526219# The issue is gone, but let us monitor it in next few days since it is a sporadic issue

Well, the issue can be seen again. https://openqa.suse.de/tests/15612615#
So, seems the issue is caused by allocating memory to vm
