I am having the same question as asked in this thread http://lists.gnu.org/archive/html/qemu-devel/2008-03/msg00399.html

I am trying to debug why my kernel crashes during the boot process. But some of the error messages scroll of the target console, before I can see what is happening.

For this, I would like to scroll the target console (My kernel crashes before init begins - I have seen that once Init begins, I can scroll up the target console using ctrl+PgUp - but before init begins the console canot be scrolled).

I tried "qemu -hda image.img -m 512M -serial vc:1024x768" (to see if I could set a bigger size for the console - so the messages wont scroll off the target console)
but this fails with
"qemu: could not open serial device vc:1024x768"

I am running qemu 0.8.2 on ubuntu and 0.8.2 on fc6.

1) Is this "vc:AxB " option supported on this version - do I need to upgrade?
2) I sthere any other way I can scroll up the target console.
3) Is there any other way to expand the target console?

Any help will be appreciated

Thanks.
Girish
