i think the stack is broken.
so the rsi value is error.

vcpu-arch.regs_avail = ~((1  VCPU_REGS_RIP) | (1  VCPU_REGS_RSP)
bf8d:   48 8b 75 98 mov-0x68(%rbp),%rsi

static __always_inline unsigned long vmcs_readl(unsigned long field)
{
unsigned long value;

asm volatile (__ex_clear(ASM_VMX_VMREAD_RDX_RAX, %0)
bf91:   ba 08 44 00 00  mov$0x4408,%edx
 */
loadsegment(ds, __USER_DS);
loadsegment(es, __USER_DS);
#endif

vcpu-arch.regs_avail = ~((1  VCPU_REGS_RIP) | (1  VCPU_REGS_RSP)
bf96:   c7 86 48 02 00 00 efmovl   $0xffe0ffef,0x248(%rsi)
