[Xen-users] switching from bridge to nat on existing domU

[Brian Krusic <brian@xxxxxxxxxx>]

Hi,

My current domU config.sxp uses the /etc/xen/scripts/vif-bridge script

I see a vif-nat script and would like my domU to use it.

I changed my config.sxp as follows;

(device
        (vif
            (bridge bond0)
            (mac 00:16:3e:3d:e0:e6)
            (script /etc/xen/scripts/vif-bridge)
            (uuid 8b3535c4-25e5-521c-e495-27f956b99fb8)
            (backend 0)
        )
)

to

(device
        (vif
            (bridge bond0)
            (mac 00:16:3e:3d:e0:e6)
            (script /etc/xen/scripts/vif-nat)
            (uuid 8b3535c4-25e5-521c-e495-27f956b99fb8)
            (backend 0)
        )
)

My Running Xen book has an example (unsure if it applies to Xen 3.4.2  
which I'm running) of also adding;
vif = [ 'ip = 10.0.10.200', ]
NETMASK="255.255.0.0"
GATEWAY="10.0.10.1"

So would my config look like this;

(device
        (vif
            (bridge bond0)
            (mac 00:16:3e:3d:e0:e6)
            (script /etc/xen/scripts/vif-nat)
            (vif = [ 'ip = 10.0.10.200', ])
            (NETMASK="255.255.0.0")
            (GATEWAY="10.0.10.1")
            (uuid 8b3535c4-25e5-521c-e495-27f956b99fb8)
            (backend 0)
        )
)


Would this then be the ip addy of my domU?

And how would I get it to like like 10.10.10.200 with a gateway of  
10.10.10.1, same subnet mask?
Basically, I would like my domU to think its still 10.0.10.200 but the  
world to think its 10.10.10.200, just a NAT.
Unsure how to do this in Xen, I've done it in VMWare but via a GUI.
