Hi dahn! It's okay, we managed to work around it. The cause of the crash was NFS (restart during a Ceph update). Libvirt was waiting for NFS and endlessly trying to mount secondary storage. This was causing the VMs to freeze because they had NFS-based config drives mounted. Mitigation was simple on one hand; restarting the host or ejecting the VM's config drive from the server was enough. However, the problem was serious because it affected the entire environment in an instant, halting 70% of virtualization. For now, we've switched from secondary storage to S3 and removed NFS from the environment as much as possible.
