Hi. Is it possible to use kvm-tool with a kernel compiled with kgdb?
I've tried adding 'kgdbwait kgdboc=ttyS0' to -p, but that doesn't seem
to work.
Thanks,
\dae

I've never tried kgdb myself but I'm rather surprised it doesn't just
work. Sasha, Cyrill, Asias, have you guys ever tried kvmtool with
kgdb?

You can either use 'kgdboc=kbd' to use it over the keyboard. I also have
a patch which uses forktty() to spawn serial consoles and redirect guest
tty's into them, but it's somewhat ugly.
Give me a day or two to make it nicer and I'll send it over.
