Try to look for a well known kernel module (so far only virtio, or kvm) to use for detecting the architecture of a kernel.

Yaniv pointed out in https://bugzilla.redhat.com/show_bug.cgi?id=1438794 that virt-v2v both doesn't install the virtio-rng driver for Windows, and doesn't give the guest a virtio-rng PCI device either. There are two problems here: Firstly the Windows virtio-rng driver isn't included in the exploded tree (/usr/share/virtio-win) so it doesn't get copied into the guest. The solution

This is a sort of follow-up to the Linux_bootloaders patch. It turns out all the kernel detection code is nicely self- contained and can therefore be moved to its own module. Rich.

Create a new module [Linux_kernels] which does all kernel detection, and also provides a place to define the kernel_info data structure. This is essentially just code motion. --- v2v/Makefile.am | 2 + v2v/convert_linux.ml | 219 +++-------------------------------------------- v2v/linux_kernels.ml | 230 ++++++++++++++++...
