[Xen-users] can''t ping from domU to dom0 and viceversa
I''ve succesfully installed xen on my fedora5 and I built up some guest
domains.
I''ve assigned manually IP addresses to them, choosing from
ones of this subnet: 10.10.232.160\28.
Now I can ping from one to
another but I''m nor able to ping dom0 (pubblic address 143.225.229.138)
neither ping guest domains from dom0. Pings don''t give responses (no
ICMP reports)
I tryed to use this configuration, reading some items
from internet:
I use a dummy interface on dom0 with IP address on the
subnet 10.10.232.160\28 (in particular 10.10.232.161) and I use this
address as default gateway for guest domains.
Here it is the routing
table for my guest domains:
[root@fc6_pristine ~]# route
Kernel IP
routing table
Destination Gateway Genmask Flags
Metric Ref Use Iface
10.10.232.160 * 255.255.255.240
U 0 0 0 eth0
default 10.10.232.161
0.0.0.0 UG 0 0 0 eth0
That''s the routing table
for domain0:
[root@localhost ~]# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
10.10.232.160 * 255.255.255.240 U 0
0 0 xenbr0
10.10.232.160 * 255.255.255.240 U
0 0 0 dummy0
143.225.229.0 *
255.255.255.0 U 0 0 0 eth0
169.254.0.0
* 255.255.0.0 U 0 0 0 eth0
default 143.225.229.254 0.0.0.0 UG 0 0 0
eth0
Finally I post also the output from ifconfig in domain0 to show
how addresses match interfaces:
[root@localhost ~]# ifconfig
dummy0

Cuold the problem depend on how interfaces are
attached to xenbr0 or Am I only missing something about classic
networking configuration?
thank you in advance
