libvirt users - Jul 2011 - Is arping useful if a VM is brought up on a different (bridged) interface/machine?

Hi,

Using libvirt/qemu/kvm VMs, if a VM has stopped on one host and then the
identical VM is started afresh on a different host, with the exact same
(bridged) VM IP, would there be a point in having the VM run arping (or
arping2) on startup to help it be quickly found on the LAN?

Or is this built in at some level already?

Or does it not apply here?

Thanks,
Whit
