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 ef    movl   $0xffe0ffef,0x248(%rsi)
