This is only lightly tested. In particularly I only tested that the non-secure-boot path still works. I didn't test it on RHEL 7.3 yet because I haven't got enough free disk space for these giant source *.ova files :-( Will try to give that a go later. Rich.

Starting with 5.2.0, libvirt has a way to select the firmware by specifying its type, provided configuration files for the firmware are shipped. Currently we start the appliance as UEFI if any of the firmware are found, so instead we can try to just set the firmware type iff: - the libvirt autoselection works - the 'efi' firmware is available The only behaviour change is that the default

First version was posted here: https://www.redhat.com/archives/libguestfs/2016-August/thread.html#00100 This is semantically the same as the first version. However I've split the patch up into two parts. In the first part, I factor out the UEFI paths so now they are created by the generator and written in the library and v2v/ directory directly, instead of the complex business of having a C

In case you configure libguestfs with a custom QEMU, e.g.: $ ./configure [...] QEMU=/path/to/qemu then the libvirt backend did not use to override it, launching the appliance with the default QEMU for libvirt. This does not change the manual emulator overriding using set-hv. Pino Toscano (2): launch: libvirt: get default QEMU from domcapabilities launch: libvirt: fix custom hypervisor

v1 was here: https://www.redhat.com/archives/libguestfs/2018-October/msg00047.html However it was broken in a few ways. First of all the documentation was broken because "/**" enhanced comments were not permitted on macros. This is fixed in the new 1/4 patch. Secondly we didn't use single_element() everywhere possible, which is fixed in the new 4/4 patch. Lastly I've

Currently we have an OCaml library for generating the qemu command line (used only by ‘virt-v2v -o qemu’). However we also generate a qemu command line in ‘lib/launch-direct.c’, and we might in future need to generate a ‘-readconfig’-compatible configuration file if we want to go beyond 10,000 drives for scalability testing. Therefore this patch series reimplements the qemu command line code as

Consolidate and extend the use of funky start_element() etc macros. Rich.

Hi, this adds an helper version struct, and uses it in the backends (for the libvirt and qemu versions) and inspection code. This also moves common code to that, so it is not repeated in many places. This should help with the small refactoring proposed with https://www.redhat.com/archives/libguestfs/2016-May/msg00070.html Thanks, Pino Toscano (2): src: start unifying version handling

libguestfs has used double and triple underscores in identifiers. These aren't valid for global names in C++. (http://stackoverflow.com/a/228797) These large but completely mechanical patches change the illegal identifiers to legal ones. Rich.

Doing qemu feature detection in the direct backend takes ~100ms because we need to run `qemu -help' and `qemu -devices ?', and each of those interacts with glibc's very slow link loader. Fixing the link loader is really hard. Instead memoize the output of those two commands. This patch series first separates all the code dealing with qemu into a separate module (src/qemu.c) and
