This describes the major changes since 2.0. Virt-v2v 2.2.0 was released on **Tuesday 10 January 2023**. ### Security When running virt-v2v as root, NBD Unix domain sockets in the v2v directory were openable by any user. We now set the directory owner so only qemu can access the sockets. See: https://bugzilla.redhat.com/show\_bug.cgi?id=2066773 (thanks Xiaodai Wang, Dr David Gilbert, Daniel Berrangé, Laszlo Ersek). ### New features New [**virt-v2v-inspector**(1)](/virt-v2v-inspector/1.md) tool. This tool can be used before conversion to collect facts about the source guest, such as number of disks, and to estimate the disk space required after conversion. Add support for NVMe devices and SATA hard disks when importing from VMware VMX files (Laszlo Ersek). Add support for importing to KubeVirt using the new **experimental** *-o kubevirt* mode. Windows 11 guests are now supported. Rocky Linux guest support has been added (Andrey Drobyshev). ### Feature removed The *-o json* mode was removed. It was intended to be used with KubeVirt but was never actually used there. Use *-o kubevirt* instead. ### Other fixes Fix detection of virtio-socket support in Linux guests (Laszlo Ersek). In addition, a semi-random guest CID is chosen in *-o qemu* mode, avoiding an error. Allow importing OVAs where the user or group name inside the tarball contains a space (Jiří Sléžka). Reject guests with snapshots when using -i vmx -it ssh (Laszlo Ersek). Improve documentation for the need to enable PasswordAuthentication on the server side when importing over SSH (Laszlo Ersek). Don't use the deprecated qemu *-balloon* option. This caused deprecation warnings with *-o qemu* mode. Use *-device* instead. Rewrite device mapping in *-o qemu* mode, removing some strange / non-existent cases like SCSI floppies. This should result in more consistent device layout when using this mode (Laszlo Ersek). Remove more left over open-vm-tools packages from Linux guests (Tim Kent). In *-o rhv-upload* mode, do not return until the VM has been created (Tomáš Golembiovský). Greatly improved vCPU model handling (Laszlo Ersek). Document extra permissions needed for non-admin conversion with VMware 7 (Ming Xie). QEMU guest agent is now installed unconditionally and where possible a virtio-serial socket is created in the guest metadata (Laszlo Ersek). In the various RHV output modes, the number of disks is now limited to 23. RHV doesn't support anything greater and would break (Laszlo Ersek). *-oo compressed* is now working again. It was temporarily broken in virt-v2v 2.0. The documentation no longer advises you to use the dangerous global "LEGACY crypto" option, but provides more targeted advice (Laszlo Ersek). Remove the LVM2 devices file during conversion (Laszlo Ersek). Add support for guests using Zstandard compressed kernel modules. Add the BOCHS DRM display driver in Linux guest initrd, to avoid a crash with some guests with graphical boot displays (Laszlo Ersek). The UEFI fallback boot loader is now fixed up if we detect that it was broken (Laszlo Ersek). Improve detection of guests using BIOS boot with GPT partitions so that we no longer confuse them with UEFI guests (Andrey Drobyshev). Fix conflict between fwcfg and qemufwcfg Windows drivers (Laszlo Ersek). Fix Windows 11 support for RHV outputs (Laszlo Ersek). ### Build changes Enable malloc debugging in tests with glibc ≥ 2.34. When using `"make check-valgrind"`, valgrind output is no longer written to separate files under *tmp/*. Instead it is written to the normal test log file. We now require ocamldep *-one-line* and *-all* options (added to ocamldep in Jan 2012). The OCaml libvirt bindings are no longer bundled. They must be available at build time. Updated the phony test images. The tests should all pass. Add compatibility with OCaml 4.14. We now require PCRE2 instead of PCRE. ### Internals New LUKS-on-LVM test added (Laszlo Ersek). Added *scripts/git.orderfile* which orders files when we prepare patches. ### Bugs fixed - https://bugzilla.redhat.com/2152465 v2v should set ovirt:id correctly after coverting windows11/2019/2022 guests to rhv via -o rhv-upload - https://bugzilla.redhat.com/2151752 qemufwcfg device cannot start or has no driver after v2v converting windows guests - https://bugzilla.redhat.com/2149863 The version of Win 11/Win 2019/Win 2022 shows incorrect on RHV after virt-v2v conversion - https://bugzilla.redhat.com/2149811 Copy newer versions of drivers for Win 11/Win 2019/Win 2022 during virt-v2v conversion - https://bugzilla.redhat.com/2149629 Win 2022 fails to boot after virt-p2v conversion from physical host with nvme disk - https://bugzilla.redhat.com/2131123 RHEL7 UEFI guest turns into black after v2v conversion - https://bugzilla.redhat.com/2116811 virt-v2v: error: internal error: assertion failed at linux\_kernels.ml, line 190, char 11 - https://bugzilla.redhat.com/2112801 RHEL9 guest hangs during boot after conversion by virt-p2v - https://bugzilla.redhat.com/2107503 RHEL 8.6 VM with "qemu64" CPU model can't start because "the CPU is incompatible with host CPU: Host CPU does not provide required features: svm" - https://bugzilla.redhat.com/2101665 "/dev/nvme0n1" is not remapped to "/dev/vda" (etc) in boot config files such as "/boot/grub2/device.map" - https://bugzilla.redhat.com/2089623 Virt-v2v can't convert rhel8.6 guest from VMware on rhel8.6 - https://bugzilla.redhat.com/2082603 virt-v2v -o qemu prints cosmetic warning: "warning: short-form boolean option 'readonly' deprecated" - https://bugzilla.redhat.com/2076013 RHEL9.1 guest can't boot into OS after v2v conversion - https://bugzilla.redhat.com/2074805 \-o qemu mode fails with: qemu-system-x86\_64: -balloon: invalid option and other problems - https://bugzilla.redhat.com/2074801 do not pass "--non-bootable --read-write" to "volume create " in openstack output module - https://bugzilla.redhat.com/2070530 Virt-v2v can't convert guest when os is installed on nvme disk via vmx+ssh - https://bugzilla.redhat.com/2070186 fix virtio-vsock check (for Linux guests) in virt-v2v - https://bugzilla.redhat.com/2069768 Import of OVA fails if the user/group name contains spaces - https://bugzilla.redhat.com/2066773 The /tmp/v2v.XXXX directory has incorrect permisison if run v2v by root - https://bugzilla.redhat.com/2062360 RFE: Virt-v2v should replace hairy "enable LEGACY crypto" advice which a more targeted mechanism - https://bugzilla.redhat.com/2059287 RFE: Rebase virt-v2v to 2.0 in RHEL 9.1 - https://bugzilla.redhat.com/2051564 \[RFE\]Limiting the maximum number of disks per guest for v2v conversions - https://bugzilla.redhat.com/2047660 Add '--compressed' support in modular v2v - https://bugzilla.redhat.com/2028764 Install the qemu-guest-agent package during the conversion process - https://bugzilla.redhat.com/2003503 There is virt-v2v warning: fstrim on guest filesystem /dev/mapper/osprober-linux-sdb1 failed if non-os disk of source guest has few/no inodes lef - https://bugzilla.redhat.com/1985827 Start or remove VM failure even v2v has already finished - https://bugzilla.redhat.com/1953286 No error shows when using virt-v2v -o rhv to convert guest to data domain - https://bugzilla.redhat.com/1938954 \-i vmx -it ssh: document percent encoding in ssh URIs - https://bugzilla.redhat.com/1883802 \-i vmx: SATA disks are not parsed - https://bugzilla.redhat.com/1854275 document that vmx+ssh "-ip" auth doesn't cover ssh / scp shell commands - https://bugzilla.redhat.com/1817050 Can't convert guest from VMware with non-admin account and vddk \>=7.0 by virt-v2v - https://bugzilla.redhat.com/1774386 input\_vmx: cleanly reject guests with snapshots when using "-it ssh" ## SEE ALSO [**virt-v2v**(1)](/virt-v2v/1.md), [**virt-v2v-release-notes-2.0**(1)](/virt-v2v-release-notes-2.0/1.md), [**virt-v2v-release-notes-1.42**(1)](/virt-v2v-release-notes-1.42/1.md), [**guestfs-release-notes-1.40**(1)](/guestfs-release-notes-1.40/1.md). ## AUTHORS Authors of virt-v2v 2.2: - Andrey Drobyshev - Emilio Herrera - Ettore Atalan - Hela Basa - Jan Kuparinen - Laszlo Ersek - Marcin Stanclik - Ming Xie - Pavel Borecki - Piotr Drąg - Richard W.M.
