Having just poked around your system, Matt, it turns out that you've turned
off CONFIG_HOTPLUG_CPU when compiling your guest.  CONFIG_HOTPLUG_CPU is
required for save/restore; you actually get a message to that effect on the
guest's console when you try to suspend the guest.

It would be nice if the tools recognised the failure, and didn't just hang.
Feel free to file a bug to that effect.  As it is, this is "expected
behaviour" at the moment.

Cheers,

Ewan.
