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 ++++++++++++++++++++++++++++++++++++++++++++++++++ v2v/linux_kernels.mli | 50 +++++++++++ 4 files ch...

Biggest change is to switch the new DTB node to /xen-core-devices instead of /xen at Stefano''s request. I also dropped the few patches title HACK etc which weren''t supposed to be there and fixed up some bits and pieces which folks commented on. George, WRT the freeze I think this is functionality which we cannot ship Xen 4.4 without. The impact is entirely constrained to the

Hi, this series adds a couple bits more in v2v to convert Debian/Ubuntu (and derived) guests. The series does not complete the support (see known issues below), but all the patches here should be fit for review and inclusion. The series does not enable the conversion, yet. Known issues: * currently tested with simple local guest images, hence needs testing with real guests on

Previously the kernel_info field 'ki_supports_virtio' really meant that the kernel supports virtio-net. That was used as a proxy to mean the kernel supports virtio in general. This change splits the field so we explicitly test for both virtio-blk and virtio-net drivers, and store the results as separate fields. Th...

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

I''ve addressed all (I think/hope) of the review comments. The main change is to expose the guest virtual platform (e.g. memory layout and interrupt usage etc) to the toolstack via the public interface. This is then used during FDT generation. I have just codified the current defacto standard layout, it''s probably not the best layout but any change can be a separate patch/series.

This series of patches makes Xen pass a (somewhat) valid device tree to dom0. The device tree for dom0 is the same as the one supplied to Xen except the memory and chosen nodes are adjusted appropriately. We don''t yet make use of the device tree to map MMIO regions or setup interrupts for the guest and we still include the UART used for Xen''s console. Note that loading Linux
