These assorted patches end up with adding virtio-scsi support to libguestfs. It passes libguestfs-test-tool, but I haven't yet tried to run the full set of tests. In theory > 26 devices can be added, but it's likely that certain parts of the daemon will break if you actually try this. This of course needs to be fixed. Thanks Paolo Bonzini for invaluable help. Rich.

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

More comprehensive support for virtio-scsi. Passes all the tests. Rich.

Two (not related to each other) refactorings: Patches 1-12 split configure.ac into smaller files using the m4_include mechanism. Patches 13-15 split out parts of guestfs.pod (ie. guestfs(3)) into three new manual pages: guestfs-hacking(3) - how to extend and contribute to libguestfs guestfs-internals(3) - architecture and internals guestfs-security(3) - security and CVEs Patch 16 is a

Userspace patches for the pci-passthrough functionality. The major updates since the last post are: - Loop to add passthrough devices in pc_init1 - Handle errors in read/write calls - Allow invocation without irq number for in-kernel irqchip Other than this, several small things were fixed according to review comments received last time.

This preliminary patch series adds a libvirt backend to libguestfs. It's for review only because although it launches the guest OK, there are some missing features that need to be implemented. The meat of the patch is in part 4/4. To save you the trouble of interpreting libxml2 fragments, an example of the generated XML and the corresponding qemu command line are attached below. Note the

QEMU upstream has broken snapshot=on ... again. These two patches stop using it entirely. Instead we run 'qemu-img create' to create overlay disks as required. Note that the libvirt and UML backends were already doing this: The libvirt backend because <transient/> has never worked, and the UML backend was running uml_mkcow because the UML-equivalent syntax of snapshot=on was

A lot of code runs 'qemu-img create' or 'truncate' to create blank disk images. In the past I resisted adding an API to do this, since it essentially duplicates what you can already do using other tools (ie. qemu-img). However this does simplify calling code quite a lot since qemu-img is somewhat error-prone to use (eg: don't try to create a disk called "foo:bar")

This rounds off hotplugging support by allowing you to add and remove drives at any stage (before and after launch). Rich.

Now that virt-p2v has its own repository [1] and releases [2], it is time to remove it from libguestfs.
