hi,
I have a VM with route-nat and 3 virtual interfaces. This is my config:
vif = [ ''ip=10.10.10.4/24, vifname=vif1.0'',
''ip=10.10.20.4/24,
vifname=vif2.0'', ''ip=10.10.30.4/24, vifname=vif3.0'' ]
And the output of dom0 ifconfig:
vif1.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF
inet addr:10.10.10.131 Bcast:0.0.0.0 Mask:255.255.255.255
UP BROADCAST MULTICAST MTU:1500 Metric:1

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

vif2.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
vif3.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF
inet addr:10.10.30.131 Bcast:0.0.0.0 Mask:255.255.255.255
UP BROADCAST MULTICAST MTU:1500 Metric:1

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:32
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
I need to know how can I change the IP address of vifx.0. I want to
set that address to
something like 10.10.10.1 or 10.10.20.1, not 10.10.10.131.
Where can I change that 131 to something else? and why is assigned like that?
thx in advance.

That is just the backend and you will not use that IP, you should only be concerned with the frontend number i.e. 10.10.10.4 which you set in the config.

That is generally a static address for each dom0 (i.e. physical machine). I would expect that the domUs on the same box would have the same gateway and the different one have different. If my understanding is correct you don''t even need to worry about the .131 number as that is not the gateway, but just a backend IP. The gateway (presumably the dom0) is typically just that , a gateway , and not usually addressed directly.
