[Qemu-devel] Debugging x86-64 apps from a 32bit host?

[Simon Peter]

Hi,

is it possible to debug e.g. a x86-64 Linux kernel running in
qemu-system-x86_64 on a 32bit host from that host with GDB?

I cross-compiled a version of GDB with x86-64 support, so it can load
the debugging symbols from the kernel (which is an ELF64 binary) and
attached that to a running qemu-system-x86_64, but it always tells me
the instruction pointer is at 0x0.

Is this supported by QEMU?

Thanks,
Simon
