Dear All,

I can confirm that recompiling the Xen dom 0 paravirt-ops kernel using gzip compression works. I can use the generated bzImage to boot up Domain 0.

If you attempt to compile the Xen Dom 0 pv-ops kernel using bzip2 compression, you won't be able to boot up Domain 0 using the generated bzImage. You will get an ELF error and kernel panic on CPU 0.

As for X server, I haven't got much luck yet.

I was able to download and compile NVIDIA's kernel module directly from official NVIDIA website for Fedora 11 Default shipping kernel. I was able to start X server successfully and launch a desktop environment using nvidia.ko.

However, if I want to compile the nvidia kernel module against Xen dom 0 pv_ops kernel sources, the kernel module compiles successfully, but when I start X, the screen becomes blank and the whole system freezes there.

Dear Marc,

I am aware that bzImage is not related to bzip2 compression at all. In fact bzImage stands for big zImage.


In the past, I was able to use bzip2 for Xen kernel in OpenSUSE 11.1 successfully. Why is it I am only able to use gzip now?

The dom0 builder only supports that as far as i know.
