✨ NAME ✨

virt-v2v-release-notes β€” the virt-v2v release notes for 2.12

🌸 DESCRIPTION 🌸

these are the release notes for virt-v2v 2.12, and they describe all the major changes since 2.10. ngl, it's a glow-up.

Virt-v2v 2.12.0 was released on 10 July 2026. πŸ—“οΈ mark your calendars, it's iconic.

πŸ¦‹ New features

  • bestie, we can now convert Debian 12 guests that use UEFI (Martin Necas). UEFI Debian girlies, your time is NOW πŸ’–
  • SLES 12 SP5 and Ubuntu 24.04 conversions now work when they use LUKS encrypted filesystems (Cole Robinson). encrypted girlies stay winning πŸ”
  • conversions of Kylin, NeoKylin and Anolis Linux distributions are enabled (grass lu). new distros just dropped πŸ‘‘
  • shiny new --no-fstrim option to disable fstrim during conversion (sarika at Platform 9). no fstrim, no problem ✨
  • new --collect option, which can be used to collect pre-conversion information like the Windows Registry and event log for later diagnosis (thanks Vadim Rozenfeld). detective mode: activated πŸ•΅οΈ
  • the -i disk input method now allows "nbd://..." URIs to be used instead of local disks β€” which means more flexible conversions, like converting from xz-compressed images (that's such a flex fr fr) πŸ”₯
  • virt-v2v-inspector(1) now includes information about XFSv4 and XFSv5 filesystems. we love filesystem lore 🧚
  • virt-v2v-in-place(1) and the virt-v2v-inspector XML output now contains suggested disk boot order information (thanks Elad Hazan). boot order said "let me introduce myself" πŸ’…

πŸ’œ Other fixes

  • fixed detection of remote files when using -it ssh mode (Ming Xie)
  • when injecting virtio-win drivers in Windows guests, we now install blnsvr.exe (the balloon server) (Cole Robinson)
  • fixed installation of Windows Vista and Windows 2008 Server R1 drivers (Cole Robinson)
  • stopped using the xfs_repair -m option (thanks Ming Xie, Eric Sandeen, Dave Chinner)
  • AGFL inconsistencies in XFS filesystems are now ignored on RHEL 7 guests (thanks Brian Foster, Eric Sandeen)
  • the Windows qemu-guest-agent installer is retried several times to work around temporary installation bugs (thanks Martin Necas, Cole Robinson)
  • the virt-v2v --key parameter now allows binary keys πŸ”‘
  • virt-v2v --firstboot scripts on Windows may now exit with code 250 to avoid rebooting after the script (Srihari Parimi)
  • an immutable /etc/resolv.conf no longer prevents conversion (Srihari Parimi)
  • we now obey cgroup v2 CPU limits (Susant Sahani)
  • fixed output filenames if the guest name contains a / character (Susant Sahani)

πŸŽ€ Documentation

  • documented how to recover the key used by Windows guests that stored the Bitlocker disk encryption key in the VMware vTPM (Ming Xie)
  • documented the pre-conversion steps required for certain guests encrypted with LUKS using vTPM (Ming Xie, Susant Sahani)
  • fixed conversion from VMware vCenter where the VMware datastore name contains some special characters (Cole Robinson)
  • documented that the PowerShell execution policy "AllSigned" will not work (thanks Martin Mecas, Ulhas Surse)
heads up: "AllSigned" = doesn't work. don't come for me, it's in the docs 😭

🌈 Build changes

  • fixed Weblate (i18n) web hooks (Rafael Fontenelle)
  • fixed and enhanced github CI checks (Cole Robinson)
  • removed the "AM_GNU_GETTEXT" macro and replaced it with simpler "LIBINTL" checks (Cole Robinson)
  • various build warnings were cleaned up (Cole Robinson)
  • fixed warnings in the configure script related to the order that various autoconf macros appear (Olaf Hering)

🫢 Internals
