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.

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?

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. -- Sasha. ^ permalink raw reply [flat|nested] 4+ messages in thread
