NAME

       virt-v2v-release-notes - virt-v2v release notes for 2.0

DESCRIPTION

       These are the release notes for virt-v2v 2.0.  This describes the major changes since
       1.42.

       No release notes were published for 1.44, so that release is covered here.

       Virt-v2v 2.0.0 was released on 14 March 2022.

   Security
       There were no security-related bugs found in this release.

   New features
       Virt-v2v has been modularised allowing external programs to examine the state of the
       conversion and inject their own copying step.  Further enhancements will be made to this
       new architecture in forthcoming releases.

       The command line is almost identical apart from some debugging features that were removed
       (see below).  The only significant difference is that the output format (-of) now has to
       be specified if it is different from the input format, whereas previous versions of
       virt-v2v would use the same output format as input format automatically.

       A lot of time was spent improving the performance of virt-v2v in common cases.

       Implement conversion of ALT Linux guests (Mikhail Gordeev).

       Many bug fixes and performance enhancements were made to oVirt imageio output (Nir
       Soffer).

       There is a new virt-v2v-in-place(1) tool which replaces the existing virt-v2v --in-place
       option.

       Virt-v2v can now convert guests which use LUKS encrypted logical volumes (Laszlo Ersek).

       Option -oo rhv-direct has been replaced by -oo rhv-proxy, and direct mode (which is much
       faster) is now the default when writing to oVirt, with proxy mode available for restricted
       network configurations (thanks: Nir Soffer).

       The following command line options were removed: --print-estimate, --debug-overlays,
       --no-copy.

       Virt-v2v no longer installs the RHEV-APT tool in Windows guests.  This tool was deprecated
       and then removed in oVirt 4.3.

       Deprecated tool virt-v2v-copy-to-local has been removed.  This was deprecated in November
       2018.

   Other fixes
       Remove reference to prl_strg driver in Windows guests to avoid BSOD (Denis Plotnikov).

       Fix conversions of UEFI Linux guests that don't provide their own fallback bootloader
       (Denis Plotnikov).

       Remove use of nbdkit-readahead-filter(1).  This filter uses a naive strategy and it had
       several negative effects on conversions.

       Remove prompts for interactive passwords.  Normally you should try to use the -ip and/or
       -op options to supply passwords.

       For Windows guests, we insert a schtasks command.  However the parameters of this command
       are timezone dependent and so it failed in non-European timezones.  (Thanks: Dinesh
       Herath, Tomáš Golembiovský, Bryan Kinney, Mark Zealey, Xiaodai Wang)

       Virt-v2v will reauthenticate with vCenter servers periodically when copying guests over
       HTTPS which stops large guests and/or slow copies taking longer than about 30 minutes from
       failing.

       Virt-v2v now sets libguestfs SMP to match number of physical host CPUs, which helps
       performance of certain conversion steps.

       Virt-v2v output to oVirt now attempts to set the machine and firmware type correctly.
       Note an exact mapping is not always possible and oVirt may ignore our recommendations
       (incorrectly) sometimes.

       Virt-v2v now generates a virtio-vsock device for guests which support it (Valeriy Vdovin).

       All guests now need at least 100 MB of free space for conversion to succeed (Ming Xie).

       Standard VGA instead of QXL is now used as the video type for converted guests (Laszlo
       Ersek).

       Older guests (eg RHEL 6) will use the virtio-transitional model after conversion.  This
       feature and the machine type are now usually determined from the libosinfo database,
       falling back to hard-coded values if libosinfo is not available (Laszlo Ersek).

       When virt-v2v prints messages to a pipe or file it no longer wraps them, making parsing
       simpler.  You can enable wrapping in this mode using --wrap (Laszlo Ersek).

       Windows guest firstboot scripts installed by virt-v2v now run in the right order, making
       network configuration happen earlier (Laszlo Ersek).

   Build changes
       libguestfs ≥ 1.44 is now required.

       nbdcopy(1) and OCaml NBD bindings, both from libnbd ≥ 1.10, are now required.

       nbdkit ≥ 1.22 is now required (Nir Soffer).

       pcre2 (instead of pcre) is now required.

       gnulib is no longer bundled or used by virt-v2v.

       OCaml ≥ 4.04 is now required.  OCaml 4.13 support has been added in this release.

       OpenSSH scp ≥ 8.8 is now required.  Earlier versions will fail because the command line
       syntax was changed incompatibly.

   Internals
       Weblate instead of Zanata is now used for translations (Pino Toscano).
