[libvirt-users] Is it possible to in live migration?
Hi all, In live migration using shared memory, there would be a following step to input the password after typing: migrate --live vm_name qemu+ssh://Destination_IP/system. . I wonder if it is possible to include the password in the URI so that the password procedure can be avoided? Thanks, Yi
You can't include password in URI, but if you use SSH to connect remote libvirt host then you may password-less SSH login, for instance: libvirt@client$ ssh-keygen -t rsa [...] Enter passphrase (empty for no passphrase): [...] libvirt@client$ ssh-copy-id -i ~/.ssh/id_rsa.pub libvirt@server Good Luck!

Thanks, Alex. How about qemu+tcp? can it be used for live migration without additional input procedure. Right now I got little information about it. Any help will be much appreicated. Yi 2012/6/25 Alex Jia <ajia@redhat.com>

To avoid security you can use TLS for encryption, but I think that for what are you searching, ssh shared keys are the best choice (and IMHO, ssh + keys is always the best choice). -- RaSca Mia Mamma Usa Linux: Niente è impossibile da capire, se lo spieghi bene! rasca@miamammausalinux.org http://www.miamammausalinux.org
I will try ssh key. Thanks, Yi 2012/6/25 RaSca <rasca@miamammausalinux.org>
