[vbox-dev] Linux VHD Boot available - download and boot your physical pc, also runs as vm

[Huihong Luo]

That should be doable. I am not familar with Haiku, but I guess it should have something like Linux's loop module? our virtual disk driver is something like the loop module, by mounting a vhd file, and acts as a dsik.

Interesting, sounds quite much like what BeOS was doing with their 
IMAGE.BE trick, except it was using hardcoded name to find the image 
(BEOS/IMAGE.BE in fat and ext2 partitions) and it was more specific ;)

I think Haiku <http://haiku-os.org/> could easily support this as well.
Our bootloader supports getting args from multiboot info though it 
doesn't use them yet. And I started to write the code to support the 
IMAGE.BE scheme as well but didn't finish, I'll have a look at 
supporting this some day.
(Our kernel currently requires using our own bootloader though our 
loader but it can easily be chained from grub.)
cf.
http://dev.haiku-os.org/browser/haiku/trunk/src/system/boot/loader

If I had time I'd propose helping with testing on the Mac as well but 
I'm too busy :p

François.
