No, this is FreeBSD CURRENT VM with single vCPU.=20
Adding additional vCPU lead to another problem. For example:
WARNING: loader(8) metadata is missing!
GDB: no debug ports present
KDB: debugger backends: ddb
KDB: current backend: ddb
APIC: Using the MPTable enumerator.
SMP: Added CPU 0 (BSP)
SMP: Added CPU 1 (AP)
