Hi I am trying to boot a patched version of Boch's BIOS on KVM. It works fine with Qemu with -no-kvm option. However I get following with KVM unhandled vm exit: 0x80000021 vcpu_id 0 rax 0000000000000000 rbx 000000000000133a rcx 0000000000000000 rdx 0000000000000008 rsi 0000000000000008 rdi 0000000000000008 rsp 00000000000011a4 rbp 00000000000011bc r8 0000000000000000 r9 0000000000000000 r10 0000000000000000 r11 0000000000000000 r12 0000000000000000 r13 0000000000000000 r14 0000000000000000 r15 0000000000000000 rip 00000000000007ca rflags 00023046 cs f000 (000f0000/0000ffff p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) ds 88f9 (00088f9b/0000ffff p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) es 0000 (00000000/0000ffff p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) ss c181 (000c1810/0000ffff p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) fs 0000 (00000000/0000ffff p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) gs 0000 (00000000/0000ffff p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) tr 0000 (fffbd000/00002088 p 1 dpl 0 db 0 s 0 type b l 0 g 0 avl 0) ldt 0000 (00000000/0000ffff p 1 dpl 0 db 0 s 0 type 2 l 0 g 0 avl 0) gdt 88f6b/30 idt 0/3ff cr0 0 cr2 0 cr3 0 cr4 0 cr8 0 efer 0 Abort I am not sure what's going on but expecting some bug in KVM and will appreciate some help. As forum don't accept posting with attachments. I can forward the BIOS image to anybody who wants to help.
