Hi,
I have taken the long and winding road and indeed it lead me to your door. I
need your help, please.
My Xen includes 2 guests. Xen itself (10.2.0.52) gets free access to the
outside world and to its guests.
Both guests however (10.2.0.54/10.2.0.55) see each other but stay under
house arrest!
Not a single ping manages to go past the bridge (xenbr0) and get an answer
from the default gateway (10.2.0.254.)
On the guest I keep seeing ''Destination Host Unreachable'',
i.e.:
#traceroute 10.2.0.254 comes back with the !H message.
I have pasted all the info I gathered in attempt to understand who locks the
guests in, but will be happy to add any further output required to get this
resolved.
I followed so many manuals and links, one that seriously caught my attention
had to do with MAC addresses issue. Could this be my case?.
Many thanks for any assistance,
Liron.

Hi,
Still facing this problem, can anyone take a look?
eth0 interface (Xen Virtual Interface) on the VM is showing growing Rx bytes
on every ifconfig command, but Tx bytes is not moving.
Also: qemu-dm log maybe has something:

I''m also adding a part of the "/var/log/xen/xend.log" In case

you need to see more from it, i''d be happy to add, but I don''t
see any
