Hello,
Per libvirt and Redhat (up to RHEL7) documentation, the
libvirt-guests daemon should be enabled to ensure that guest VMs are
properly shutdown/suspended if the KVM host is shutdown/rebooted. I
understand that in addition to other changes, Redhat moved from the
'monolithic' libvirtd service model to the 'modular' multiple service
model. Out of the box, the systemd libvirt-guests.service is disabled,
and testing shows that the associated qemu-kvm processes for virtual
machines are simply killed as the various virt* services are stopped as
part of the systemd shutdown target.
Did Redhat just decide to fork libvirt and do their own thing, or
there some equivalent way to get the same clean shutdown behavior which
libvirt-guests used to provide?
