i don't have access to my win box from here but if i remember well you need to do this:

create a vmac
create the VM and add an ethernet device using the vmac created and vmbr0
follow the procedure for the windows ip

hope this help

IIRC the default out of the box install you should be using vmbr0 not vmbr1.

im posting for help herein case anyone knows what i missed before support get back to me im installing a windows guest assigned vmac then followed instrucions here
http://help.ovh.co.uk/Proxmox
ip route add YOUR_IP_FAILOVER dev vmbr1
Commands to use with Windows OS:

configure windows with IP failover. Netmask (255.255.255.255) won't be accepted, so put temporarly "255.255.255.0"
change netmask with registry editor to avoid problems in the future:
click on "start" - > "execute"
write "regedit" and confirm
search in HKEY_LOCAL_MACHINE\SYSTEM\ key "SubnetMask" with "255.255.255.0" value and change it to "255.255.255.255"

this didnt work so i reead and tried doing this way

http://help.ovh.co.uk/BridgeClient neither way seems to work are these complete or do i need be doing something else on the host to configure bridging?
