    OpenBSD 6.1 slow root login, slow service restart and system reboot

    OpenBSD 6.1 guest hängt

    Hallo zusammen Ich habe auf einer Mini-Umgebung mit Intel NUC 6i5SYH (neuestes 062 BIOS) und neustem PVE 5.0 mit OpenBSD 6.1 Guest-VMs immer wieder Hänger. Unter pve 4.x war dies rocksolid, erst seit PVE manchmal hängts sogar täglich! Es spielt keine Rolle, ob es frisch installierte oder...
