Does Virtual Box offer similar feature of QEMU's -s and -S?

[KGG]

Hello guy,

On Linux host, I would like to debug Linux kernel (on a VM) with virtual box. I want to use gdb tcp port (not serial port). So does Virtual Box offer similar feature of QEMU's -s and -S?

-s: open tcp port for gdb server, for debugger
-S: when starting VM kernel, suspend VM till a remote debugger has been attached.

If yes, great, how to do that?

If no, sorry, I've stick to QEMU.

Why would we know what QEMU does?

Anyway, see the user manual section 12.1.3. This describes what VirtualBox does, which sounds similar.

I guess you care your customers, who are influenced by your competitors.

I took a quick look. They are not the same thing. But thanks for your reply, anyway.

Um... a free download doesn't make you Oracle's customer. Oracle charges big money for support. Those are their customers, which they certainly do care about.

Also, this is a user self help forum. Almost everyone you will encounter here (including myself) will be other users, not Oracle employees. For them I imagine we are merely a test resource.

Make sense, to some extend, though.

"uninstall it" and "do not touch it again" seems best option to me.

Sounds good to me too. Perhaps you missed the part about these being user forums: if you are not a user then we don't need you.
