breaking kvm :-)

breaking kvm :-)

[ron minnich]

Somebody here at OLS was asking me about linuxbios on kvm. Well, that
was too much to resist.

Short form: it works, uses a grub-like interface that does not use
BIOS callbacks. It's noticeably faster to boot than Bochs. I realize
that it's all pretty fast but linuxbios is 32-bit code, so there is
pretty much no emulation to worry about.

So, if anyone gets annoyed watching bochs boot, I can put a howto on
the linuxbios wiki. It's pretty trivial to set up.

Please do, I'd like to try it out.

Very nice. I'm curious though since I've never used Linuxbios before:
what operating systems can it load? Only Linux, anything that comes
as an ELF image, or even proprietary operating systems?

pretty soon, anything grub can load. For now, ELF arbitrary elf images.

Hi Ron,

This would be interesting to try, especially if booting is noticeably 
faster that bochs.

Did you get that how-to up?

Thanks,
Cam

[ron minnich]

Ah, I need to get that how-to up, only Anthony tried it and he never
seems to need a HOWTO :-)

thanks, I am glad you are interested, I will test it again and
probably put a HOWTO up at linuxbios.org, which could be cloned at the
kvm web site.
