NAME

6       virt-v2v-release-notes - virt-v2v release notes for 2.0
7

DESCRIPTION

9       These are the release notes for virt-v2v 2.0.  This describes the major
10       changes since 1.42.
11
12       No release notes were published for 1.44, so that release is covered
13       here.
14
15       Virt-v2v 2.0.0 was released on 14 March 2022.
16
17   Security
18       There were no security-related bugs found in this release.
19
20   New features
21       Virt-v2v has been modularised allowing external programs to examine the
22       state of the conversion and inject their own copying step.  Further
23       enhancements will be made to this new architecture in forthcoming
24       releases.
25
26       The command line is almost identical apart from some debugging features
27       that were removed (see below).  The only significant difference is that
28       the output format (-of) now has to be specified if it is different from
29       the input format, whereas previous versions of virt-v2v would use the
30       same output format as input format automatically.
31
32       A lot of time was spent improving the performance of virt-v2v in common
33       cases.
34
35       Implement conversion of ALT Linux guests (Mikhail Gordeev).
36
37       Many bug fixes and performance enhancements were made to oVirt imageio
38       output (Nir Soffer).
39
40       There is a new virt-v2v-in-place(1) tool which replaces the existing
41       virt-v2v --in-place option.
42
43       Virt-v2v can now convert guests which use LUKS encrypted logical
44       volumes (Laszlo Ersek).
45
46       Option -oo rhv-direct has been replaced by -oo rhv-proxy, and direct
47       mode (which is much faster) is now the default when writing to oVirt,
48       with proxy mode available for restricted network configurations
49       (thanks: Nir Soffer).
50
51       The following command line options were removed: --print-estimate,
52       --debug-overlays, --no-copy.
53
54       Virt-v2v no longer installs the RHEV-APT tool in Windows guests.  This
55       tool was deprecated and then removed in oVirt 4.3.
56
57       Deprecated tool virt-v2v-copy-to-local has been removed.  This was
58       deprecated in November 2018.
59
60   Other fixes
61       Remove reference to prl_strg driver in Windows guests to avoid BSOD
62       (Denis Plotnikov).
63
64       Fix conversions of UEFI Linux guests that don't provide their own
65       fallback bootloader (Denis Plotnikov).
66
67       Remove use of nbdkit-readahead-filter(1).  This filter uses a naive
68       strategy and it had several negative effects on conversions.
69
70       Remove prompts for interactive passwords.  Normally you should try to
71       use the -ip and/or -op options to supply passwords.
72
73       For Windows guests, we insert a schtasks command.  However the
74       parameters of this command are timezone dependent and so it failed in
75       non-European timezones.  (Thanks: Dinesh Herath, Tomáš Golembiovský,
76       Bryan Kinney, Mark Zealey, Xiaodai Wang)
77
78       Virt-v2v will reauthenticate with vCenter servers periodically when
79       copying guests over HTTPS which stops large guests and/or slow copies
80       taking longer than about 30 minutes from failing.
81
82       Virt-v2v now sets libguestfs SMP to match number of physical host CPUs,
83       which helps performance of certain conversion steps.
84
85       Virt-v2v output to oVirt now attempts to set the machine and firmware
86       type correctly.  Note an exact mapping is not always possible and oVirt
87       may ignore our recommendations (incorrectly) sometimes.
88
89       Virt-v2v now generates a virtio-vsock device for guests which support
90       it (Valeriy Vdovin).
91
92       All guests now need at least 100 MB of free space for conversion to
93       succeed (Ming Xie).
94
95       Standard VGA instead of QXL is now used as the video type for converted
96       guests (Laszlo Ersek).
97
98       Older guests (eg RHEL 6) will use the virtio-transitional model after
99       conversion.  This feature and the machine type are now usually
100       determined from the libosinfo database, falling back to hard-coded
101       values if libosinfo is not available (Laszlo Ersek).
102
103       When virt-v2v prints messages to a pipe or file it no longer wraps
104       them, making parsing simpler.  You can enable wrapping in this mode
105       using --wrap (Laszlo Ersek).
106
107       Windows guest firstboot scripts installed by virt-v2v now run in the
108       right order, making network configuration happen earlier (Laszlo
109       Ersek).
110
111   Build changes
112       libguestfs ≥ 1.44 is now required.
113
114       nbdcopy(1) and OCaml NBD bindings, both from libnbd ≥ 1.10, are now
115       required.
116
117       nbdkit ≥ 1.22 is now required (Nir Soffer).
118
119       pcre2 (instead of pcre) is now required.
120
121       gnulib is no longer bundled or used by virt-v2v.
122
123       OCaml ≥ 4.04 is now required.  OCaml 4.13 support has been added in
124       this release.
125
126       OpenSSH scp ≥ 8.8 is now required.  Earlier versions will fail because
127       the command line syntax was changed incompatibly.
128
129   Internals
130       Weblate instead of Zanata is now used for translations (Pino Toscano).
