I'm seeing the very same problem, please reopen. Ubuntu 12.10 amd64 (Linux 3.5.0-25-generic x86_64), qemu-kvm 1.2.0+noroms-0ubuntu2.12.10.3. Guest is an i386 eCos test kernel (I can attach it if necessary; I guess you can use anything bootable here), started either via qemu-system-i386 -kernel ecos.elf -s -S or via an ISO image with grub2: qemu-system-i386 -cdrom ecos.iso -s -S
I'm attaching GDB with: gdb ecos.elf (gdb) target remote localhost:1234 (gdb) b main (gdb) c The breakpoint never hits, although this perfectly works on my 32-bit Debian Squeeze box. If I start qemu-system-i386 with "-machine accel=tcg", the breakpoint matches very quickly, kvm halts, and the GDB prompt allows me to inspect the state. If I start qemu-system-i386 with "-machine accel=kvm" (the default), I observe the aforementioned behaviour. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/901944 Title: gdbserver inside qemu does not stop on breakpoints To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/901944/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
