virt-v2v release notes for 2.4

Description

These are the release notes for virt-v2v 2.4. This describes the major changes since 2.2.

Virt-v2v 2.4.0 was released on 5 January 2024.

New features

New --block-driver option which can be used to choose to install either virtio-blk or virtio-scsi drivers (Andrey Drobyshev).

The virt-v2v --key option now recognizes LVM names like /dev/mapper/rhel_bootp--73--75--123-root (Laszlo Ersek).

The --key option also supports a new --key all:... selector to try the same key on all devices.

Feature removed

Support for RHEL 3 conversions has been removed.

Other fixes

Conversions now set the host-model CPU in the output metadata, except where the source hypervisor overrides this.  The exception is -o qemu mode which uses -cpu host.  (Thanks Ming Xie, Laszlo Ersek, Dr. David Alan Gilbert, Daniel Berrangé)

virt-v2v will now look for bootloader configuration in /boot/grub/grub.cfg for UEFI guests (Andrey Drobyshev).

Invoke pnputil (if available) to install drivers, fixing some Windows conversions (Andrey Drobyshev).

Skip SELinux relabelling if the guest has disabled SELinux (Roman Kagan).

Several output modes now generate metadata to indicate whether the guest requires the RTC to be set to UTC (Linux) or localtime (most Windows).  For example with -o libvirt this generates <clock offset="utc|localtime"/>.  (Thanks Lee Garrett, Laszlo Ersek)

-i ova mode is now less strict about parsing the manifest file, which helps when converting some non-conforming OVA files.

Input modes using -it ssh now use the correct quoting (thanks Bill Sanders, Laszlo Ersek).

-i vmx mode now rejects VMDK files explicitly, reducing a source of user confusion (thanks Ming Xie).

Multiple fixes to -o kubevirt mode.  Also implement -oo compressed for this mode.  (Thanks Xiaodai Wang, Ming Xie)

-o libvirt mode now supports Rocky Linux (thanks Ming Xie).

-o openstack documentation for cloud configurations fixed (thanks Ming Xie).

-o rhv-upload mode has an improved error when the -os parameter is invalid or missing (thanks Junqin Zhou).

Build changes

Support for OCaml 5, and OCaml ≥ 4.07 is now the minimum (thanks Guillaume Munch-Maccagnoni, Jerry James, Josh Berdine, Jürgen Hötzel, Vincent Laviron).

Fix several tests so they can handle the case where the operating system does not support btrfs or NTFS, instead of failing (Laszlo Ersek).

Fix compatibility issues with libxml2 2.12.

Internals

Fix an off-by-one error which caused very rare crashes in virt-v2v.
