+First Guest Boot Delay
+~~~~~~~~~~~~~~~~~~~~~~
+
+In case your VMs/containers rely on slow-to-start external resources, for
+example an NFS server, you can also set a per-node delay between the time {pve}
+boots and the time the first VM/container that is configured to autostart boots
+(see xref:qm_startup_and_shutdown[Automatic Start and Shutdown of Virtual Machines]).
+
+You can achieve this by setting the following (where `10` represents the delay
+in seconds):
+
+----
+pvenode config set --startall-onboot-delay 10
