[Xen-users] Network VIFs in xen-3.1 guest do not start up

Hi,



i configured a
vif = [''mac=aa:00:00:00:01:08, bridge=xenbr0'']

ip="192.168.0.11"
netmask="255.255.255.0"
gateway="192.168.0.1"

in my xen config.

As I boot, no network card gets up in my guest system.

ifconfig -a shows me all network cards, but the ip isn''t being static.

There are guests systems running which should not being able to change 
the ip adress.


How do I get that?


Thanks,
Amin

Re: [Xen-users] Network VIFs in xen-3.1 guest do not start up

Hi, for changing ip, netmask and gateway have to change the
/etc/network/interface file in guest machine, before start.
Mount the disk.img file and modify the file
for example

auto eth0
iface eth0 inet static
address 192.168.0.11
netmask 255.255.255.0
gateway 192.168.0.1

Next start the machine will work all.

Regards.

Re: [Xen-users] Network VIFs in xen-3.1 guest do not start up

No I don''t mean linux Dom0...

i know that this is in /etc/network/interfaces

by the way I''m using Debian Etch 4.0


My Problem was about the DomU / Guests for which i created a xen config 
file.

As they start up they have a NIC but no IP/Netmask/gateway Information 
with it AND
i don''t want to allow THEM to provide a IP.



!!!It should be defined in the xen config file (like 2.0.6)!!!
to prohibit them to change the IP / to cause damage by doing that.


Thx,
Amin

RE: [Xen-users] Network VIFs in xen-3.1 guest do not start up

AFAIK, there is no way you can prevent them from changing it afterwards anyways.
EVEN if you can autoconfigure the NIC, they will be able to change it''s
config afterwards. Also, if you refer to the Xen manual for the version 3
branch, there are no directive of that sort included in the config files syntax.

Someone might correct me on that matter though...

Re: [Xen-users] Network VIFs in xen-3.1 guest do not start up

Hi Amin,

you can use ebtables on dom0 to filter arp packets.  The guest will
still be able to change the IP, but you prevent them from sending arp
replies for anything but their allowed IP address.
