similar to: [PATCH] Replace -nodefconfig with -no-user-config.

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

Since it does not make much sense, then forbid this situation outright: - change qemuopts_end_arg_list() to return an error if the current arg list has no elements - when creating the argv array, assert that each arg list is not empty --- common/qemuopts/qemuopts.c | 14 ++++++++++++-- 1 file changed, 12 insertions(+), 2 deletions(-) diff --git a/common/qemuopts/qemuopts.c

Call realloc() directly with the pointer to the old data, instead of assigning it to the destination variable, and using that one.

From: Nikolay Ivanets <stenavin@gmail.com> I faced with situation where libguestfs cannot recognize partitions on a disk image which was partitioned on a system with "4K native" sector size support. In order to fix the issue we need to allow users to specify desired physical and/or logical block size per drive basis. It is definitely not a complete patch but rather a way to

Heya, With latest Fedora Rawhide Kernel, I see a nested KVM guest hanging at boot (not unusual). Rich once suggested this[1] to try to attach gdb to the nested L2 guest to find out where_ it's stuck, tonight I set out to try it out (with KVM & TCG). Below is all what I tried. In guest hypervisor (L1): $ git clone git://github.com/libguestfs/libguestfs.git $ git log | head -1

virtio-scsi has been supported in qemu since 2012, and it is superior in every respect to virtio-blk. There's no reason to still be using virtio-blk. virtio-scsi support was initially added in 2012 (commit 0c0a7d0d868d153adf0600189f771459e1068b0a). You can still use virtio-blk using the (deprecated) iface parameter, but don't do that in new code. --- lib/guestfs-internal.h | 1 -

Add a copy of the libvirt-ocaml library, currently available at: https://libvirt.org/git/?p=libvirt-ocaml.git;a=summary This is a snapshot at commit d3ed8dcf1b0a6a8a855ceecbe0bb97f21e6665e3, which has all the features we need (and that builds fine). It is expected to stay synchronized with upstream, until there is a new upstream release, and it will be widespread enough. --- .gitignore

Use also custom_compare_ext_default for the compare_ext field. According to the git logs, this was introduced in OCaml 3.12.1, which is earlier than out minimum required version. mlaugeas is not touched by this change, since it is a copy of a 3rd party library (and thus it will be fixed there first). --- common/mlpcre/pcre-c.c | 3 ++- common/mlprogress/progress-c.c | 3 ++-

This patch adds a 'raid' interface class. It is basically a clone of the existing 'scsi' interface, only allowing up to 128 disks.
