Host reboot and automatic VM restart with teleport support

Let's assume I have the following hardware:

one iSCSI targets where the VM images are located
two text-console-only hosts with VirtualBox 3.1.x

How can I to handle this use case:

Reboot both host1 and host2
Let's assume host1 is faster to reboot
host1 starts vm1 automatically (how?)
host2 detects (how?) that vm1 is already running so it waits for a teleport request
Manually trigger teleport vm1 to host2
Reboot host1 (e.g. after system upgrade)
host1 detects that vm1 is already running so it waits for a teleport request

Please share your real-life examples with scripts and ready-to-run commands...
