Hi There.
I am in the process of "upgrading" my Xen 2.0.7 server with a Xen
3.0.2,
though I am doing so on a different machine. My firewall will be running as
a DomU, asit also does on the existing server.
The new server is Ubuntu 6.06 and the existing server is Debian Sarge.
On the existing server, I have the WAN interface hidden from Dom0 with the two
other physical interfaces plus a dummy interface tied to "untethered"
bridges
(as I also have physical switches plugged into the "LAN" and
"DMZ"
interfaces).
Here is what the ''/etc/network/nterfaces'' file looks like:
auto br-lan0 br-dmz0 br-adm0
iface br-lan0 inet manual
bridge_ports eth0
iface br-dmz0 inet manual
bridge_ports eth1
iface br-adm0 inet static
address 10.253.3.2
netmask 255.255.255.0
gateway 10.253.3.1
bridge_ports dummy0
the ''br-adm0'' bridge is for remote administration of Dom0.
The firewall DomU
is of course tied to all three bridges.
My current issue is that when I try to set the above up on the new Xen 3
machine, from the Dom0, I am unable to ping the DomU firewall''s
interface
that is tied to the ''br-adm0'' bridge, which has the IP address
''10.253.3.1''.
I get "Destination Host unreachable"
Has anyone done this sucessfully under Xen 3 (untethered interfaces)? If so,
is there a pointer to to a HOWTO or Wiki, or other thoughts that goes through
this?
I look forward to your thoughts. Thanks in advance! :-)
