Remote Kernel Debugging over QEMU?

[Yoshihiro Ota]

Hello, folks,

Has anyone tried to remote-debugging of a system running on Qemu?

I thought if I could attach kgdb from Qemu host to a guest FreeBSD
running on Qemu, it would be very helpful for many reasons, i.e.
no hardware requirements, avoid fscking all disks, and so on.

Has anyone ever attempted?  I spent a half day but due to lack of
remote debugging experience and some other knowledge, it wasn't
successful.

Thanks,
Hiro
