Se suele solucionar con

certctl rehash

Las VMS con red virtio tienen un rendimiento muy lento por defecto que se puede solucionar desactivando checksum offload (TCO/RCO).

    ifconfig <interface> -rxcsum -txcsum -tso4 -tso6 -lro -vlanhwtso
    
    
    
    Add hw.vtnet.X.csum_disable=1 to /boot/loader.conf 
    
    
    Alternatively, to load VirtIO support as	modules	at  boot  time,	 place
       the following lines in loader.conf(5):

	     virtio_load="YES"
	     virtio_pci_load="YES"

Similar al anterior pero aplicable a maquinas fisicas
