Unit libvirtd.service could not be found. on VM

Hi all, Some background: I recently has some issues with libvirt on my laptop when I got the error 'operation failed: pool 'default' already exists with uuid dd48b6ad-9a00-46eb-a3a4-c122d8a294a5' when I connected virt-manager. I was finally able to resolve it yesterday, when I removed libvirt and all its related content in /etc/libvirt, removed the pool by its UUID, deleted virbr0 & virbro-nic, removed the default network, reinstalled and created the network & default pool again Now I got libvirtd on my laptop up & running. However, when I install vms on my laptop, they don't have libvirtd.service This is the network configuration XML: <interface type="network"> <mac address="52:54:00:d0:40:69"/> <source network="default" portid="171a745c-f96d-412a-baa7-ee1feeaed6ac" bridge="virbr0"/> <target dev="vnet1"/> <model type="virtio"/> <alias name="net0"/> <address type="pci" domain="0x0000" bus="0x00" slot="0x03" function="0x0"/> </interface> I installed the vms with virt-manager. The Network source is Virtual network 'default': NAT I'm using CentOS8.1 on both my laptop & vms. Is there anything else I need to reconfigure or any thoughts why libvirtd.service doesn't exist on my VMS? Thanks, Dana
