I would like to create a Vm server using a hyper-visor and have it replicated to another physical box so that if the main hyper-visor or Vm goes down the second one takes over. Is there a way to do this in virtual-box or another hyper-visor ? I have heard ESXi can do this but my hardware does not support ESXi apparently.
For virtual box we have two different ways to replicate a machine to a different host.
- Clone a virtual machine:
This will make a clone of the current VM with, or witout snapshots. This will make the virtual machines identical except their UUID. The clone can then transported to another host.
- Teleporting a virtual machine
This feature allows to teleport a running machine to a different host in the network. Then the other host can overtake with little downtime.
