Re: [Xen-users] One nic multiple ip's

[nomid <mikahuhta@xxxxxxxxxxx>]

Current /etc/network/interfaces settings:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 193.34.X.88
netmask 255.255.255.128
gateway 193.34.X.1

auto eth0:0
iface eth0:0 inet static
        address 93.104.X.230
        netmask 255.255.255.128
        gateway 193.34.X.1

auto eth0:1
iface eth0:1 inet static
        address 93.104.X.231
        netmask 255.255.255.128
        gateway 193.34.x.1
..
.
.
ip's are 193.34.X.88 and 93.104.x.230 - .233

Now all ip's working. If i try 93.104 adress on domU. 
Dom0 can acces net, but DomU not.

Off cource i remove other Virtual nic berore testing xen. (if try these
settings boot xen, eth0 gone)
