[one-users] How to reboot a host without migrating the VMs running on it?

[Ruben S. Montero]

Probably: poweroff or suspend the VMs, then reboot the host. Once the host
is back online just resume the VMs... (double check that any shared FS is
properly mounted, specially those with the VM disk images)

You can also use --hard in case your VMs are not "ACPI aware". Note that
suspends saves the VM state.

Cheers
