about migration

Hi,
    To do migration, why vdsm/libvirt requires DNS server or hostnames
in hosts file? Is there any way to do migration directly with IP
address?

If you address your hosts via FQDN, these requirements apply. When
address them by their IP addresses, the DNS requirements should go away.

I think there was an old libvirt api which required reverse dns 
resolution, and a new one that did not.
not sure if vdsm moved yet to the new one.

Upstream uses migrateToURI2.
wangxiaofan, which version are you using? Do you use ssl?
