Eu tenho tentado configurar o OpenNebula no ambiente de teste consiste em dois hosts:
nebula contém:

Eu posso implantar a VM com imagem para o hipervisor via Sunstone. Esta imagem é iniciada com sucesso. Mas não consigo terminar a VM devido a erros:

Como devo organizar o intercâmbio entre máquinas frontais e hipervisores com o armazenamento de dados LVM para resolver este problema?
O problema foi resolvido no fórum do OpenNebula por mim.
Resumindo:
I’ve been solved my problem particularly by removing default System Datastore with id 0. Now, VM instances are creating in right VG (vg-one-104 instead of vg-one-0). I don’t know if it’s right behavior (removing default System Datastore) but it’s work for me by now. So, also VM instance terminate correctly. I set this topic as solved.
