...This currently does not cause failures, however it "just works" because of the tricky situation set up. The situation is the following: 1) common/utils contains few utility sources: one of them is utils.c, which contains various functions -- for example guestfs_int_free_string_list and guestfs_int_drive_name --, it is built as utils.o, and bundled in the static library libutils.a 2) common/mlutils builds a OCaml library with bindings for some utility functions in libutils.a, in particular guestfs_int_drive_name (but not guestfs_int_free_string_list); there are two versions of this library, one OCaml l...

This patch series adds stable bus and slot numbers for removable drives (CDs and floppies) when the guest is converted using virt-v2v or virt-p2v. Previously we were a bit random about this. After this patch series, the bus and slot numbers and preserved if at all possible. BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1238053 Rich.

By passing root=UUID=... to supermin, we make the appliance boot process less sensitive to the non-deterministic process of scanning SCSI disks (of which much more to come). This patch should be tested alongside the supermin patch posted here: https://www.redhat.com/archives/libguestfs/2017-April/msg00174.html which in turn requires this supermin patch series:

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/2020-February/msg00220.html This patch series is a little bit better. It's still a bit of a hack. The _real_ fix for this is outlined in the TODO file (see patch 1) but that requires a lot more work than we could do before 1.42 is released, unless we delay 1.42 for a lot longer. I'm hoping with this to have something which works

As discussed in the thread on validating $TERM, it would be good to have a common function to do this. This is such a function. The main advantage is it includes unit tests which the previous functions did not. Rich.

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.

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1792141 Let the user pass "-oo" options from the kernel cmdline and from the GUI to virt-v2v. This is primarily useful with the OpenStack output mode, so reenable that mode. Cc: Alban Lecorps <alban.lecorps at ubisoft.com> Laszlo Alban Lecorps (1): Introduce "p2v.output.misc" for passing "-oo" options

Hi, as it was already discussed on this list, here it is my attempt in splitting virt-p2v in an own repository. Sadly there are things that must be copied from libguestfs, as it cannot be avoided. The approach taken was to run a script (will send separately) to just get the "p2v" subdirectory with its history as own repository, and then add in few followup commits all the bits needed

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