FailOver IP

[Christian Hermann <c.hermann@xxxxxxxxxxx>]

hi guys!
i`am new to libvirt and i want using kvm with a ipv4 failover 
ip-address. so this addres has the netmask 255.255.255.255.
this ip is directly bind to my root server by my provider. so i can not 
use it on an other server.
can you tell me how i can use this ip address on a kvm virtual maschine, 
build with libvirt?


Kind regards,

Chris
