Support for VIA Nano X2 L4350 — at Version 2

Description (last modified by Frank Mehnert)

The VIA Nano X2 L4350 processor supports hardware virtualization (Intel VT-x).

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?

I'm afraid that we don't have any VIA hardware, and it is probably not an important market for us. If you could provide us with either hardware or a well-tested patch though we would consider supporting it.
