Beam me up Scotty: Teleport with VirtualBox 3.1

with 2 comments

Read this on virtualization.info:

VirtualBox 3.1 is now capable of performing a virtual machine live migration, called Teleportation, between remote hosts over a standard TCP/IP network link.

Of course, because the virtualization layer sits above the host operating system, VirtualBox has limited compatibility issues with different CPU families, and no problems with different operating systems.

To work, Teleportation requires that both copies of VirtualBox have two identical VMs with same virtual hardware. These two VMs must access the same shared storage (NFS/CIFS, iSCSI or Fibre Channel).

Despite what the press release claims, the user manual highlights that teleporting a VM between an AMD and an Intel CPU may fail, despite VirtualBox is able to simulate the each other differences to a degree.

This feature seems analogous to VMware’s vMotion, except that there isn’t an ESX hypervisor providing a portablity/hardware abstraction layer.

  1. but this version also allows to change an existing VM using the VBoxManage tool and modifyvm option so that:

    –synthcpu on|off: This setting determines whether VirtualBox will expose a synthetic CPU to the guest to allow live migration between host systems that differ significantly.

  2. Seems pretty cool. Looking forward to test it.
    I’m used to ESX VMotion, and it’s an missing feature to move more stuff to Virtualbox.
