Hi All, I am trying to debug guest OS through qemu with kvm enabled. Following is what I have done: 1: fire the qemu-kvm <snip> sudo qemu-system-x86_64 -hda vdisk.img -m 4096 -smp 2 -vnc :2 -boot c -s </snip>
2: wait until login into guest OS (ubuntu 10.04) 3: fire gdb <snip> gdb vmlinux target remote :1234 b do_fork set arch i386:x86-64 c </snip> 4: after I typed "ls" in guest OS. The guest OS paniced with some message related to "int 3 blah blah". Then crashed. Someone said we should use hardware breakpoint when kvm is enabled, or "monitor system_reset" after set the breakpoint, but it didn't work for me. The hardware breakpoint could not been hit anyway. I have tried with "-no-kvm", it works normally with breakpoints. But I want to debug the guest OS with kvm enabled. I don't know whether someone has met this similar situation. Thanks for your time! Best Wishes, Yaohui
