Hi, I'm having trouble getting kvm to work on my system. The host has 2 dual-core Intel Xeon 5130 CPUs (flags: lm vmx) and is running Linux 2.6.20.1 with kvm-15 (although I've had no luck with kvm-12 or kvm-14 either)
If I take (for example) the NetBSD amd64 installation: ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-3.1/amd64/installation/cdrom/amd64cd-3.1.iso and run it with qemu-img create hda.img 4G qemu-system-x86_64 -cdrom amd64cd-3.1.iso -hda hda.img -boot d then the screen flashes briefly but qemu crashes with unhandled vm exit: 0x80000021 rax 0000000000000000 rbx 0000000000000000 rcx 0000000000000000 rdx 0000000000000600 rsi 0000000000000000 rdi 0000000000000000 rsp 0000000000000000 rbp 0000000000000000 r8 0000000000000000 r9 0000000000000000 r10 0000000000000000 r11 0000000000000000 r12 0000000000000000 r13 0000000000000000 r14 0000000000000000 r15 0000000000000000 rip 000000000000fff0 rflags 00023002 cs f000 (ffff0000/0000ffff p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) ds 0000 (00000000/0000ffff 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 0000 (00000000/0000ffff 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 (08850000/00002088 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 0 l 0 g 0 avl 0) gdt 0/ffff idt 0/ffff cr0 60000010 cr2 0 cr3 0 cr4 0 cr8 0 efer 0 Aborted If I try to run it without kvm: qemu-system-x86_64 -no-kvm -cdrom amd64cd-3.1.iso -hda hda.img -boot d Then I get a blank SDL window that is entirely frozen (can't even switch to the qemu monitor). If I use a stock qemu 0.8.2 to boot the cdrom and run the installer, then try to boot the resulting disk image with kvm: qemu-system-x86_64 -hda hda.img -boot c qemu-system-x86_64 -no-kvm -hda hda.img -boot c then I get the exact same results -- the first crashes with "unhandled vm exit" and the second freezes. Any suggestions? Also, on the Linux side of things, I have a disk image from a computer that also crashes when I try to boot it. It dies with "exception 14" after Grub. But, it does work fine with -no-kvm. The kernel it's booting is a 32-bit k7 optimized kernel; is it expected behavior for that to work fine under -no-kvm but crash on an Intel host? -jim ------------------------------------------------------------------------- Take Surveys.
