Hi,
I''ve two xen-servers (xen2.07) running on Debian, both with two network
interface cards in them.
This is the configuration of the interfaces in dom0
(/etc/network/interfaces):
auto eth0
iface eth0 inet static
address 192.168.16.76
netmask 255.255.255.0
network 192.168.16.0
broadcast 192.168.16.255
gateway 192.168.16.77
dns-nameservers 192.168.16.66
dns-search mycompany.com
auto eth1
iface eth1 inet static
address 192.168.20.251
netmask 255.255.255.0
network 192.168.20.0
broadcast 192.168.20.255
With this configuration, but interfaces are working. I can reach both
networks from the xen-server itself, and I can reach both interface from
other systems on the network. I have several virtual servers connected
to the 192.168.16.* network, all working fine. So far, so good.
Today, I started setting up a server which should run in the
192.168.20.* network. From what I have read on the internet, I need to
add a bridge for the new network. With the command
"/etc/xen/scripts/network start bridge=xen-br1 netdev=eth1", I am able
to add the bridge for the 192.168.20.* network. But.. uhoh.. all virtual
servers on the 192.168.16.* segment lost their connection. The servers
are able to ping 192.168.16.76 (the xen-server itself) but other
adresses fail. Same for the virtual server I created in the 192.168.20.*
network. (on this server, I added "vif=[ ''bridge=xen-br1''
]" to the
server-config, is that correct?).
So, the xen-server itself is still reachable, but the virtual servers
running on it are not. Xen-server is able to reach the virtual servers,
and the virtual servers are able to reach the xen-server.
What am I doing wrong? I can''t find any good documentation on this
subject :(
Thanks for any help,
Kris
