[Xen-users] Xen 3.0 on FC4 - guest domains cant ping host domain

I am installed Xen 3.0 on a Fedora Core 4(2.6.12-1.1454_FC4xen0) machine.  
This machine is currently running one host domain:

[root@]# xm list

Following is the network configuration for Domain-0:

When I try to ping the Domain-0(192.168.1.110) from fc4-vm1(192.168.1.121), 
I get :

PING 192.168.1.110 (192.168.1.110) 56(84) bytes of data

I tried messing around with the routing table without any success.  Any help 
is appreciated.

RE: [Xen-users] Xen 3.0 on FC4 - guest domains cant ping host domain

This sounds identical to my problem when I try to use the NAT networking
model.  What network model are you trying to use?  Bridge (the default, NAT,
or Route?

I just recently installed Xen3 on a FC5 host and a FC4 guest, and it worked
perfectly until I changed it to the NAT model.

As far as why yours isn''t working, we would have to see your xen config
file
for the domU.

RE: [Xen-users] Xen 3.0 on FC4 - guest domains cant ping host domain

I am using the default  (Bridged) network model.  Following is network 
configuraitons from my  xend-config.sxp file:

<--------------------------------------/etc/xen/xend-config.sxp 
-------------------------------------->
     ## Use the following if VIF traffic is routed.
     # The script used to start/stop networking for xend.
     #(network-script     network-route)
     # The default script used to control virtual interfaces.
     #(vif-script         vif-route)

     ## Use the following if VIF traffic is bridged.
     # The script used to start/stop networking for xend.
     (network-script    network-bridge)

     # The default bridge that virtual interfaces should be connected to.
     (vif-bridge        xen-br0)

     # The default script used to control virtual interfaces.
     (vif-script        vif-bridge)

     # Whether iptables should be set up to prevent IP spoofing for
     # virtual interfaces. Specify ''yes'' or
''no''.
     (vif-antispoof     no)
<----------------------------------------------------------------------------------------------------->

I found an artcle online and tried following it and created a bridge, but 
that didn''t remedy either:

[  http://www.linuxdevcenter.com/pub/a/linux/2006/01/26/xen.html?page=2  ]

<--------------------------------------Bridge 
Creation-------------------------------------->
     [root@seleya ~]# brctl show
     bridge name     bridge id               STP enabled     interfaces
     xen-br0              8000.feffffffffff        no                       
peth0
                                                                             
            vif0.0
     [root@seleya ~]# brctl addbr xen-br1
     [root@seleya ~]# brctl addif xen-br1 vif1.0
     [root@seleya ~]# brctl addif xen-br1 eth0
<------------------------------------End of Bridge 
Creation------------------------------------>

The machine loses all network connectivity after adding eth0 to the bridge 
xen-br1.

What''s the

The output is supposed to be
bridge name  bridge id           STP  enabled interfaces
xen-br0      8000.feffffffffff   no   peth0
                                      vif0.0
                                      vif1.0

Try doing "brctl addif xen-br0 vif1.0". It''s unclear from
your post if vif0.0 is
also part of the brige. If it''s not you need to add it also. In normal
circumstances the vif*.* is supposed to be added automatically.

Ubaidul Khan wrote:> Made the changes you recommended, but still having the same problem.
Can you install ethereal (or tethereal of don''t have X) on your
machine? Open up
 a few ethereal windows and listen on eth0(dom0), vif0.0, vif1.0, xen-br0,
eth0(domU).

Then do some pings from one dom to another. eth0(dom0) and vif0.0 should then
show exactly the same traffic. the same is for eth0(domU) and vif1.0. Is that
the case?
