Re: [Xen-users] ROUTING

[Carlo <carlo@xxxxxxxxxxx>]

When I type from a domU shell "ifup eth0", system say "eth0: duplicate
address detected!"
But in the lan there are not two ip address or
two MAC that can make conflicts.

dom0 have two nics configured
in bonding and they work fine.

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
