Thanks for the additional information. You are right: `machinectl list` does list the VMs managed by libvirt:
==================================== $ virsh list Id Name State --------------------------------------- 9 rbasak-gu-build running 10 rbasak-gu running 11 rbasak-gu-focalorigin running 12 paride-uvt-i running $ machinectl list MACHINE CLASS SERVICE OS VERSION ADDRESSES qemu-10-rbasak-gu vm libvirt-qemu - - - qemu-11-rbasak-gu-focalorigin vm libvirt-qemu - - - qemu-12-paride-uvt-i vm libvirt-qemu - - - qemu-9-rbasak-gu-build vm libvirt-qemu - - - 4 machines listed. ==================================== But in my case stopping systemd-machined does not affect the VMs: ==================================== $ sudo systemctl stop systemd-machined $ virsh list Id Name State --------------------------------------- 9 rbasak-gu-build running 10 rbasak-gu running 11 rbasak-gu-focalorigin running 12 paride-uvt-i running # ^^ note, still running ^^ $ uvt-kvm ssh paride-uvt-i Welcome to Ubuntu Impish Indri (development branch) (GNU/Linux 5.11.0-20-generic x86_64) [...] ubuntu@paride-uvt-i:~$ uptime 14:40:51 up 3 days, 4:58, 1 user, load average: 0.00, 0.00, 0.00 # ^^ and actually working with no downtime ^^ ubuntu@paride-uvt-i:~$ logout Connection to 192.168.122.184 closed. $ systemctl is-active systemd-machined inactive # ^^ machined still inactive ^^ ==================================== However this is done using Impish (both host and guest) and not Focal. TODO to complete the triage of this bug is: try the same on Focal. If it works (= stopping systemd-machined doesn't stop the VMs) then the reported problem may be a local configuration issue. Otherwise we'll have to search for what's causing the difference. @Helmut: feedback from your side is appreciated here. If you can try to reproduce the issue with Impish and share your findings, great! Also I think it's worth triple-checking that the your misbehaving Focal system doesn't have any change that can cause machined kill the VMs when it stops.
