These are the release notes for virt-v2v2.6. This describes the major changes since 2.4.
Virt-v2v 2.6.0 was released on 8October2024.
Newfeatures
You can now use most virt-customize(1) options, such as installing arbitrary firstboot scripts, uploading
or editing files, etc. during conversions.
Installation of QEMU Guest Agent in Windows guests has been revised and made much more reliable. Note
that a visible effect of this change is that Windows guests may reboot four or more times during the
first boot after conversion (which is necessary). (Thanks Vadim Rozenfeld, Konstantin Kostiuk, Yuri
Benditovich, Yan Vugenfirer).
We now forcibly online all virtio disks during firstboot, working around a security mitigation in recent
versions of Windows that offlines them if they change bus (Martin Necas).
QEMU Balloon Server (blnsvr) is now installed in Windows guests, if found on the virtio-win ISO. This
improves statistics gathering for these guests.
Add support for Circle Linux (Bella Zhang).
Add some support for LoongArch guests (liuxiang).
Otherfixes-iova mode now uses the detected guest firmware, if it's not specified in the OVA metadata (Bella
Khizgiyaev).
-okubevirt output mode has been substantially changed to fix multiple problems. It should be more
compatible with real KubeVirt instances now. (Thanks Arik Hadas, Bella Khizgiyaev, Lee Yarwood, Martin
Necas).
-olibvirt mode now includes an <os firmware> attribute specifying whether the guest needs BIOS or UEFI
to boot.
The output of virt-v2v-inspector(1) has been revised, with much more metadata available.
The --mac option now allows the gateway and network mask length to be empty (Arik Hadas).
The debug output of virt-v2v has been improved. Now when searching the log for important events, you can
just use the regular expression "/^info:/"
Buildchanges
We no longer require external ssh/scp commands for input mode -ivmx. Instead we use
nbdkit-ssh-plugin(1) (this is not a new requirement as it is already being used for file transfer). This
makes remote file detection more predictable, and also allows the -ip option to be used to specify a
password. (Thanks Ming Xie, Laszlo Ersek).
OCaml bytecode compilation now outputs the whole exe to make it more resistant to being stripped (Jerry
James).
Multiple test files which were copied over from libguestfs but not actually used by virt-v2v tests have
been deleted.
Internals
Added a test for -okubevirt mode.
