IBM Cloud: 各OSに含まれているvirt-v2vとnbdkit VDDK pluginの状況について

はじめに

IBM CloudのVSI for VPCで提供されている最新Linuxにおいて、virt-v2vのバージョンと--block-driverオプションの有無を確認してみた。
RHEL系列は別Buildになるという話だったが、OSの種類によっていろいろ変わってた。調査した結果は以下のとおり。

OS	virt-v2v version	virt-v2v --block-driver option	nbdkit VDDK plugin
Rocky 9	virt-v2v 2.5.6rhel=9,release=8.el9_5	Not Included	Included
CentOS 9	virt-v2v 2.7.1rhel=9,release=19.el9	Not Included	Included
CentOS 10	virt-v2v 2.9.10rhel=10,release=1.el10	Not Included	Included
RHEL 9	virt-v2v 2.7.1rhel=9,release=12.el9_6	Not Included	Included
Fedora CoreOS 43	virt-v2v 2.9.10fedora=43,release=1.fc43	Included	Included
Debian 13	virt-v2v 2.6.0	Included	Not Included
Ubuntu 24	virt-v2v 2.4.0	Included	Not Included

Network Block Device (NBD) is a network protocol for accessing block
devices over the network.  Block devices are hard disks and things that
behave like hard disks such as disk images and virtual machines.

nbdkit is both a toolkit for creating NBD servers from “unconventional”
sources, and the name of an NBD server.  nbdkit ships with many plugins
for performing common tasks like serving local files.

Please read the nbdkit(1) manual page for full usage.

Network Block Device (NBD) is a network protocol for accessing block
devices over the network.  Block devices are hard disks and things that
behave like hard disks such as disk images and virtual machines.

nbdkit is both a toolkit for creating NBD servers from “unconventional”
sources, and the name of an NBD server.  nbdkit ships with many plugins
for performing common tasks like serving local files.

Please read the nbdkit(1) manual page for full usage.

plugin: vddk (VMware VDDK plugin)
(/usr/lib64/nbdkit/plugins/nbdkit-vddk-plugin.so)
[file=]<FILENAME>              The filename (eg. VMDK file) to serve.
export=<WILDCARD>              Let client choose file matching wildcard.
Many optional parameters are supported, see nbdkit-vddk-plugin(1).

ただし、SUSEのlibvirtはvpx driverをnativeサポートしていないようです。
