Hi Michael, Looks like the discussions tapered off, but do you have a plan to implement this if people are eventually fine with it? We want to extend this to support multiple VMs. On Mon, Aug 31, 2015 at 11:35 AM, Nakajima, Jun wrote: > On Mon, Aug 31, 2015 at 7:11 AM, Michael S. Tsirkin wr

2007-05-01 Thread 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 (

We found a way to get 32-bit Vista up on KVM by fixing bios.bin. And I think it should be helpful to qemu as well. However, I'm not sure if the binary file has been created simply by applying bios.diff to the latest bochs CVS tree (actually I doubt it). Can somebody provide a recipe for creating bi
