Hi,
I''ve done a lot of searching on Google, on the xen officiel website,
but
nothing helped me to fix my problem and I tried a few examples !
Here is the situation, I manage a dedicated server, there are two IPs,
one for dom0 and one (failover) ip for the domU. Le problem is with the
domU. I made it, fine, I ran it, fine, to simplify things :
Both Ips -> eth0 on dom0 (it uses the first ip, eth0) and there is the
second ip (dummy0)--> domU (using the second ip)
Here is the interface file on dom0 for the second IP :
auto dummy0
iface dummy0 inet static
address XX.XX.XX.XX # the second ip
broadcast XX.XX.XX.255
netmask 255.255.255.255
In the domU configuration file :
vif = [ ''ip=192.168.1.2'' ''bridge=xendmz''
''ip=XX.XX.XX.XX''] ##
XX.XX.XX.XX = the second ip
And on the domU :
auto eth0
iface eth0 inet static
address 192.168.1.2
gateway 192.168.1.1
netmask 255.255.255.0
Well the problem is, I don''t have the second ip on the domU, I
can''t
ping outside, and I can''t ping to the domU (from the first ip, and from
outside).
I tried a few options with route, but it''s not good, not yet !
Do I need to route, on the dom0, to route all packets for the second ip
to the domU ? How ? I didn''t find the good rules with iptables.
No documentation simply explains this...
Thanks,
Regards,
