The CPU flag is recognized by VirtualBox: {{{ 00:00:00.369 VMX - Virtual Machine Technology = 0 (1) }}} But CPU itself is unknown: {{{ 00:00:00.502 HWACCM: No VT-x or AMD-V CPU extension found. Reason VERR_HWACCM_UNKNOWN_CPU 00:00:00.502 HWACCM: VMX MSR_IA32_FEATURE_CONTROL=0 }}} VirtualBox guests therefor don't have hardware virtualization. Would it be possible to support this CPU?
