Re: [Xen-users] network setup

["mr_ala" <mr_ala@xxxxxxxxxxxxx>]

Thanks for link.

I followed instructions at the page it points to, but wasn't success.
Firstly, I altered xend configuration to:

(network-script network-nat)
(vif-script     vif-nat)

Then, I also changed my domain's config file to include following lines:
dhcp="off"
vif=['mac=00:16:3e:00:00:12']
ip="10.0.0.2"
hostname="simulant"
netmask="255.255.255.0"
gateway="10.0.0.254"

And then copied the script setup_nat - which sets up NAT and IP forwarding -
to /etc/xen, restarted xend, created the domain and ran /etc/xen/setup_nat.

What seems strange to me is that if I now invoke "ifconfig vif10.0" in Dom0, i
get:

vif10.0   Zapouzdření:Ethernet  HWadr FE:FF:FF:FF:FF:FF  
          inet adr:10.0.10.128  Všesměr:0.0.0.0 Maska:255.255.255.255
          inet6-adr: fe80::fcff:ffff:feff:ffff/64 Rozsah:Linka
          AKTIVOVÁNO VŠESMĚROVÉ_VYSÍLÁNÍ BĚŽÍ MULTICAST  MTU:1500  Metrika:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:6 overruns:0 carrier:0
          kolizí:0 délka odchozí fronty:0 
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

(To make it easier for those whose Czech is not as good as they'd like it to
be, IP address is 10.0.10.128, broadcast 0.0.0.0, netmask 255.255.255.255)

I'd expect it to be 10.0.0.2 with netmask 255.255.255.0, since this is what i
put in the config file.

Anyway, when I now log into the domain and run "ifconfig" there, result is just
lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

So, eth0 is not configured, I guess. Routing table is empty. And I am not able
to ping anything.

I tried to go ahead by configuring DomU's eth0 using data which I put in its
config file:

ifconfig eth0 10.0.0.2 netmask 255.255.255.0
route add default gw 10.0.0.254

and try to ping again (I am pinging 10.0.0.254, and 131.155.145.254 which is
IP of Dom0's eth0 interface). All i get is "Destination Host unreachable".

My last attempt to make it work is to set vif10.0's data in the shape I would
suppose correct, thus:
ifconfig vif10.0 10.0.0.2 netmask 255.255.255.0

and ping again from the guest domain. But everything is unreachable, again.

Can you give me any hints, please?
