in Oracle Linux Virtualization Manager (OLVM) (MOSC) 6 commentsAnswered ✓

Hello !

Our windows administrators have been installing  MS Windows 2022 server virtual machines under OLVM cluster (three nodes -KVM hosts ) and error situations occurred under kvm-host1 (but not in other kvm hosts)  where messages such as "VM .. is down with error.“ Exit message: Lost connection with qemu process" have appeared in the OLVM Vitualization manager event log.

See also /var/log/libvirt/qemu in the logs of virtual machines in logs like these lines:
