Re: [ Re: unhandled vm exit: 0x80000021 vcpu_id 0]
Hi Pier The only thing I can tell that is, seems guest completely messed up... It ran into some non-code segment. > unhandled vm exit: 0x8021 vcpu_id 0 > rax 0007 rbx 1490 rcx rdx > 19a0 rsi rdi rsp > 0080 rbp 96bf r8 r9 > r10 r11 r12 > r13 r14 r15 > rip 002a rflags 00023202 > cs 14a2 (/ p 0 dpl 0 db 0 s 0 type 9 l 0 g 0 avl 0) > ds 19a0 (/ p 0 dpl 0 db 0 s 0 type 0 l 0 g 0 avl 0) > es 1a31 (/ p 0 dpl 0 db 0 s 0 type 0 l 0 g 0 avl 0) > ss 1a29 (/ p 0 dpl 0 db 0 s 0 type 1 l 0 g 0 avl 0) Segments maybe messed up... > fs (/ p 0 dpl 0 db 0 s 0 type 0 l 0 g 0 avl 0) > gs (/ p 0 dpl 0 db 0 s 0 type 0 l 0 g 0 avl 0) > tr 0058 (00201ffa/ p 1 dpl 0 db 0 s 0 type b l 0 g 0 avl 0) > ldt (/ p 0 dpl 0 db 0 s 0 type 0 l 0 g 0 avl 0) > gdt 20/1dd8 > idt 201df0/188 > cr0 8019 cr2 0 cr3 144 cr4 0 cr8 0 efer 0 CR0.PE set(sorry for wrong decode before...), CR0.PG set. Guest in protected mode. But CR4 is wrong, at least CR4.PAE and CR4.VMXE should be set. > code: 00 f0 53 ff 00 f0 53 ff 00 f0 a5 fe 00 f0 87 e9 00 f0 53 ff --> 00 f0 > 53 ff 00 f0 53 ff 00 f0 53 ff 00 f0 57 ef 00 f0 53 ff 00 f0 3a 83 00 c0 4d > f8 00 f0 Seems like meaningless code... Well, still don't know what the "checkpoint" done caused this... At least it seems more than a emulation bug. Anybody else have idea?... -- regards Yang, Sheng -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
