Hi,

I have a succesfull XEN 2.06 installation with a DomU running with it's rootfs 
over NFS. I can migrate this GuestOS between hosts on the same switches 
network. I connect to my GuestOS over tcp (ssh).
The transfer of the GuestOS takes about 4 seconds, and with the live option it 
should be for a very short period where the GuestOS actually is stopped.
After the transfer it takes 20-30 seconds before the GuestOS becomes 
responsive again. Which kind of timeout it this?

When you move an IP address to another MAC address you typically send out an 
unsolicited ARP to update the arp caches on the other hosts on the network to 
ensure correct routing at once.
Are there any similar thing I could do to make sure that the switch will 
broadcast the next packet for the MAC address that suddenly has moved to 
another port?

Regards,
--
