Hi Simone, I tried to change the number of cores and, after a reboot, the cpu model has changed to Nehalem. The HostedEngine vm is now migrating correctly. I will open a ticket anyway pointing to this specific behavior. Thank you very much for the support! -- Stefano Stagnaro Prisma Telecom Testing S.r.l.
