Re: [Xen-users] Bonding – dom0 or dom1 ? and why is vif1.1 missing in DomU?

["Ian Brown" <ianbrn@xxxxxxxxx>]

Thanks, Jerry.

 - I am looking at this 3 pages Dell pdf doc and will try something like it.

 - A question:
 It is said there that :
"The bridge and the bond should be configured to disable Address
Resolution Protocol (ARP) and multicast. In the test environment,"
and this should be done by:

# ip link set xenbr1 arp off
# ip link set xenbr1 multicast off

Does anybody knows why this is so ?

Regards,
Ian
