Hi,
I''m trying to get Xen in a route setup with CentOS5 both as dom0 and
domU running. Bridge setup was working.
dom0
ip: 88.xxx.xx.151/27
gw: 88.xxx.xx.129
domU:
ip: 78.xx.xxx.114/32
dom0 ifconfig:
eth0 Link encap:Ethernet HWaddr 00:E0:4D:05:AA:70

dom0 route:
78.xx.xxx.114 dev vif1.0 scope link src 88.xxx.xx.151
88.xxx.xx.128/27 dev eth0 proto kernel scope link src 88.xxx.xx.151
default via 88.xxx.xx.129 dev eth0
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
78.xx.xxx.114 0.0.0.0 255.255.255.255 UH 0 0 0 vif1.0
88.xxx.xx.128 0.0.0.0 255.255.255.224 U 0 0 0 eth0
0.0.0.0 88.xxx.xx.129 0.0.0.0 UG 0 0 0 eth0
domU config:
# Automatically generated xen config file
...
vif = [ ''ip=78.xx.xxx.114'', ]
...
in the domU:
# Xen Virtual Ethernet
DEVICE=eth0
BOOTPROTO=static
IPADDR=78.xx.xxx.114
NETMASK=255.255.255.255
ONBOOT=yes
added
ip route add default dev eth0
manually on the domU, routing now:
ip route
default dev eth0 scope link
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 eth0
I can ping the dom0 from the domU and vice versa. But I can''t access
internet from the domU, a traceroute always stops at the dom0 ip.
ip_forward and proxyarp for ezh0 and vif1.0 are set.
Any idea?
