[Qemu-devel] [PATCH] Getting 32-bit Vista on KVM

[Qemu-devel] [PATCH] Getting 32-bit Vista on KVM

[Nakajima, Jun]

Now I realized that I needed to use 32-bit Linux to build the bios.bin
(i.e. BIOS-bochs-latest) in bochs. As long as I used x86-64 Linux to
build bios.bin, the resulting binary had a problem, as I reported
previously.

With this very simple patch, I was able to install and run 32-bit Vista
on KVM (almost the latest tree) on the 64-bit host. Thanks Qing for
debuging this. I believe this should work for Qemu as well.

A patch for this has been recently posted to Bochs-developers:

(the official list archive doesn't seem to work at the moment)
