Hi, Since two weeks I am experiencing the same problem. I also noticed this first when performing "apt upgrade" command. Suspected systemd as I often saw problems when it was being installed or triggered, such as when services were being restarted or reloaded probably.
I too am on HP hardware: DL380 G6 BIOS Information Processor Information Version: Intel(R) Xeon(R) CPU E5530 @ 2.40GHz If I shutdown the virtual machines and keep libvirtd.service running then "systemctl daemon-reload" works fine. The moment I have one virtual machine running the machine crashes. In attachment you can find what I get in "journalctl -f" open in other terminal. Regards, peter
