8 Starting and Stopping libvirtd

The communication between the virtualization solutions (KVM, Xen, LXC) and the libvirt API is managed by the daemon libvirtd, which needs to run on the VM Host Server. libvirt client applications such as virt-manager, possibly running on a remote machine, communicate with libvirtd running on the VM Host Server, which services the request using native hypervisor APIs. Use the following commands to start and stop libvirtd or check its status: 

root # systemctl start libvirtd

root # systemctl status libvirtd
libvirtd.service - Virtualization daemon
Loaded: loaded (/usr/lib/systemd/system/libvirtd.service; enabled)
Active: active (running) since Mon 2014-05-12 08:49:40 EDT; 2s ago
[...]

root # systemctl stop libvirtd

root # systemctl status libvirtd
[...]
Active: inactive (dead) since Mon 2014-05-12 08:51:11 EDT; 4s ago
[...]

To automatically start libvirtd at boot time, either activate it using the YaST Services Manager module or by entering the following command: 

root # systemctl enable libvirtd
