Encontrou o problema.
Esqueci de ativar o APIC de E / S para máquinas virtuais que pretendo usar no modo de 64 bits.
vboxmanage modifyvm "Node1" --ioapic on
sovled o problema. Meu mal.
Eu criei e configurei a VM com 8 cpus (no servidor com 48 cpus).
Aqui vboxmanage showvminfo output:
Memory size: 40960MB
Page Fusion: off
VRAM size: 8MB
CPU exec cap: 100%
HPET: off
Chipset: piix3
Firmware: BIOS
Number of CPUs: 8
PAE: on
Long Mode: on
CPUID Portability Level: 0
When i login to vm, and use command 'nproc' the output is 1.
Além disso, a saída de cat /proc/cpuinfo é:

É assim que supõe ser? Ou talvez eu esteja fazendo algo errado?
