[Libguestfs] ANNOUNCE: virt-v2v 2.12 released

I'm pleased to announce the latest stable release of virt-v2v, 2.12. Virt-v2v is a tool that can automatically convert VMs from foreign hypervisors like VMware over to KVM. This version has a few new features and extends compatibility over more types of guests. The release notes for this version can be found online at this link, or attached below. https://libguestfs.org/virt-v2v-release-notes-2.12.1.html Tarballs from: https://download.libguestfs.org/virt-v2v/2.12-stable/ Rich. Virt-v2v 2.12.0 was released on 10 July 2026. New features Enable conversions of Debian 12 guests that use UEFI (Martin Necas). Enable conversions of SLES 12 SP5 and Ubuntu 24.04 that use LUKS encrypted filesystems (Cole Robinson). Enable conversions of Kylin, NeoKylin and Anolis Linux distributions (grass lu). Add new --no-fstrim option to disable fstrim during conversion (sarika at Platform 9). New --collect option which can be used to collect pre-conversion informa‐ tion such as the Windows Registry and event log for later diagnosis (thanks Vadim Rozenfeld). The -i disk input method now allows "nbd://..." URIs to be used instead of local disks. This allows more flexible conversions such as converting from xz-compressed images. virt-v2v-inspector(1) now includes information about XFSv4 and XFSv5 filesystems. virt-v2v-in-place(1) and virt-v2v-inspector XML output now contains sug‐ gested disk boot order information (thanks Elad Hazan). Other fixes Fix detection of remote files when using -it ssh mode (Ming Xie). When injecting virtio-win drivers in Windows guests, install blnsvr.exe (the balloon server) (Cole Robinson). Fix installation of Windows Vista and Windows 2008 Server R1 drivers (Cole Robinson). Stop using xfs_repair -m option (thanks Ming Xie, Eric Sandeen, Dave Chin‐ ner). Ignore AGFL inconsistencies in XFS filesystems on RHEL 7 guests (thanks Brian Foster, Eric Sandeen). Retry Windows qemu-guest-agent installer several times to work around tem‐ porary installation bugs (thanks Martin Necas, Cole Robinson). Virt-v2v --key parameter now allows binary keys. Virt-v2v --firstboot scripts on Windows may now exit with code 250 to avoid rebooting after the script (Srihari Parimi). Immutable /etc/resolv.conf no longer prevents conversion (Srihari Parimi). Obey cgroup v2 CPU limits (Susant Sahani). Fix output filenames if guest name contains "/" character (Susant Sahani). Documentation Document how to recover the key used by Windows guests that stored the Bitlocker disk encryption key in the VMware vTPM (Ming Xie). Document pre-conversion steps required for certain guests encrypted with LUKS using vTPM (Ming Xie, Susant Sahani). Fix conversion from VMware vCenter where the VMware datastore name con‐ tains some special characters (Cole Robinson). Document that the PowerShell execution policy "AllSigned" will not work (thanks Martin Mecas, Ulhas Surse). Build changes Fix Weblate (i18n) web hooks (Rafael Fontenelle). Fix and enhance github CI checks (Cole Robinson). Remove "AM_GNU_GETTEXT" macro and replace it with simpler "LIBINTL" checks (Cole Robinson). Various build warnings were cleaned up (Cole Robinson). Fix warnings in configure script related to the order that various auto‐ conf macros appear (Olaf Hering). Internals Many memory leaks identified by Claude Code were fixed (shivanayak). Improve debug output (Srihari Parimi).
