I'm pleased to announce the release of virt-v2v 2.0. This is a major
revision of our tool for converting guests from foreign hypervisors
(VMware, Xen) to run on KVM-based hypervisors. A great deal of
architectural change has been done to ensure we're in a better place
with performance and future enhancements, and at the same time many
bugs have been fixed.
You can download virt-v2v 2.0 source from:

Please note if building from source that the build requirements have
changed quite a bit. See the "Build changes" section of the release
notes.

----------------------------------------------------------------------
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Option -oo rhv-direct has been replaced by -oo rhv-proxy, and direct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, Tom?? Golembiovsk?,
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).
