Re: [one-users] Safe Live Migration
Migration is done using this command (KVM) in the host where the VM is running (/var/lib/one/remotes/vmm/kvm/migrate): virsh --connect $LIBVIRT_URI migrate --live $deploy_id $QEMU_PROTOCOL://$dest_host/system With the default configuration the migration data then will be sent to $dest_host using unencrypted tcp sockets. In case the interface for $dest_host IP is not used for the VM bridge then it will be only used for ssh connections, migrations and maybe storage (depends on the configuration). In case you want to use an interface only for migration you may want to create a new network (attached to a new interface) and add a suffix to the host names. For example: 192.168.10.15 host01 10.0.0.15 host01.migration And change the migration command to something like this: virsh --connect $LIBVIRT_URI migrate --live $deploy_id $QEMU_PROTOCOL://$dest_host.migration/system To encrypt data you'd better check libvirt documentation on how to use tls for connections. It will require generating certificates and configuration in libvirt, not only QEMU_PROTOCOL modification.

Re: [one-users] Safe Live Migration
Hi, This is mostly a hypervisor related question. What hypervisor are you using? cheers, Jaime On Wed, Jan 22, 2014 at 10:12 AM, Igor Laskovy wrote: > Anybody?
