Apache cloudstack: Não é possível adicionar instâncias usando um modelo criado a partir do instantâneo

Question

Eu segui este link e instalei o cloudstack do apache com rede básica na minha máquina local, e tudo funcionou bem.

Eu posso adicionar instâncias do modelo minúsculo embutido do linux (cent-os 5.6 64bit) sem nenhum problema.

Eu obtive um instantâneo do volume da instância em execução e criei um modelo a partir dele. Quando tento adicionar uma instância usando esse modelo, sempre obtenho InsufficientServerCapacityException.

De acordo com o meu painel, há capacidade suficiente para adicionar a instância. Alguma idéia?

console:
