Re: [Xen-users] ROUTING

[Carlo <carlo@xxxxxxxxxxx>]

Found: if I type "ifconfig" in my dom0 I can see all the mac adress (dom0
and domU).
All domU nics have FE:FF:FF:FF:FF:FF.
Why?
In the cfg
file I have putted a unique mac address:
mac=UNIQUEMAC.

Thanks,


Carlo

That basically means the system doesn't have an arp (mac address  to  ipaddress ) entry for the host you are trying to ping

run arp -e  you'll see there's an incomplete entry for the host you are trying to ping.

MAC address solved, but problem not.
When I ping domUB from domUA (ping IPNUMBER), it say "icmp_seq=1 Destination Host Unreachable".

Ideas?


Thanks,

Carlo

Hi Carlo,

is it possible that you have on both machines the same MAC adress? I had a
simmilar problem and the reason was that to virtual machines had the same
MAC adress.

Bye
