Getting new sh*t around the block, having new roots at OVH, cool offers, nice machines, decent services, okay price, worst UI for management webinterface ever :_)
first, get two of your 3 failover IPs and attach them to your rootserver.
to get xen bridged running you need to create virtual mac addresses in the ovh manager. assign those to the vif section of the domU config:
vif = [ 'ip=184.108.40.206,mac=02:00:00:00:00:01,vifname=vif.serv01', 'ip=220.127.116.11,mac=02:00:00:00:00:02,vifname=vif.serv02' ]
use in xend-config.sxp
(network-script 'network-bridge antispoof=yes') (vif-script vif-bridge)
and in domU /etc/network/interfaces easy as this:
auto eth0 iface eth0 inet static address 18.104.22.168 netmask 255.255.255.255 broadcast 22.214.171.124 post-up /sbin/ip route add default dev eth0 auto eth1 iface eth1 inet static address 126.96.36.199 netmask 255.255.255.255 broadcast 188.8.131.52 post-up /sbin/ip rule add from 184.108.40.206 lookup 100 post-up /sbin/ip route add default dev eth1 table 100
