During the inspection of Apple reference, I have noticed that Guest CR0 and CR0 Guest/Host Mask has incorrect value. Apple defines that Guest CR0 is writable only if:
CR0.CD and CR0.NW are unset

But hvf accel code follows Intel SDM "Table 9-1. IA-32 and Intel 64 Processor States Following Power-up, Reset, or INIT" and sets CR0 value to: 0x60000010

Likewise, CR0 Guest/Host Mask is conditionally writable if:
CR0.CD and CR0.NW are set

I doubt if it's related to the HV_ERROR issue but I'll prepare a patch to fix both fields (and likely set CR0 Read Shadow).
