That means the Hypervisor didn't really like the configuration
generated by ldomctl(8) and booted with the factory-defeault
configuration. There might have been some messages on the console
about this during the reset of the machine.
The ldomctl(8) code isn't very good at checking various constraints.
The most common problem is that there isn't actually enough memory for
the domains. The Hypervisor needs some memory too so you can't
actually use all the memory in the system. But how much memory is
needed by the Hypervisor isn't always obvious. I recommend testing a
configuration where you explicitly assign memory to each domain and
leave at least 512MB of memory unassigned.
