Virt-v2v is a program for converting virtual machines to run on KVM, ones imported from other hypervisors like VMware, Xen and more, and with the companion tool virt-p2v from physical machines too. I'm pleased to announce the release of virt-v2v 1.42. This is a new stable branch. Significantly the tool is now released separately and on a different schedule from libguestfs.

New features This is the first release where virt-v2v lives in a separate repository from libguestfs. The two projects are now broadly decoupled from one another. Add a new -o json output mode. Primarily this is used to do conversions to KubeVirt (Pino Toscano). Use new libvirt "<firmware>" feature to get the source guest firmware (Pino Toscano). virt-v2v -o rhv-upload new option -oo rhv-disk-uuid allows disk UUIDs to be specified. Also -oo rhv-cafile is now optional (Pino Toscano). Conversions over ssh now use nbdkit-ssh-plugin(1) instead of the QEMU ssh driver. Similarly nbdkit-curl-plugin(1) is used instead of the QEMU curl driver. This allowed us to add more flexible features such as password authentication, bandwidth throttling (new --bandwidth option), readahead, and automatic retry on network failures. For Windows guests, QEMU Guest Agent MSI may now be installed (Tomáš Golembiovský). Other fixes In -o libvirt mode, support Windows Server 2019 (Pino Toscano). Fix Ubuntu Server conversions (Pino Toscano). Fix installation of qemu-ga by only installing arch-specific files in the guest (Pino Toscano). Delay installation of qemu-ga until after virtio-win drivers have been installed and rebooted (Tomáš Golembiovský). Save the log from running RHEV-APT installer to allow debugging (Tomáš Golembiovský). Check RHV cluster exists before trying to convert when using -o rhv- upload mode. Also allows us to detect and reject various other conditions early. (Pino Toscano). Label nbdkit sockets correctly for SELinux/sVirt (Martin Kletzander). You can use a block device as the Windows virtio driver ISO. Multiple fixes to RHV uploads: Set "DISKTYPE" field correctly when converting to RHV and VDSM. Properly clean up on failure. Display disk ID in error messages, and log script parameters, to help with debugging. Multiple code cleanups. (Nir Soffer). Support conversions to RHV in qcow2 format (Nir Soffer). Fix detection of disk status and failures after conversion to RHV (Daniel Erez). Cancel disk transfer and remove uploaded disks on failure of conversion to RHV (Pino Toscano). Images containing small holes (sparse regions) should now convert faster (Nir Soffer). The nbdkit-cacheextents-filter(1) is used to accelerate sources which have slow sparseness detection, primarily this means VMware sources using VDDK (Martin Kletzander). Require at least 100 free inodes on each guest filesystem before doing conversion, since lack of inodes could cause conversion failures (Pino Toscano). Fix osinfo output for CentOS 8 conversions (Pino Toscano). VMware tools are now removed from Windows guests automatically in most cases (Pino Toscano). -i ova mode no longer reads the whole input OVF into memory, but parses it off disk (Pino Toscano). When converting to OpenStack, we now wait up to 5 minutes (instead of 60 seconds) for the Cinder volume to get attached to the conversion appliance, since in some cases it was taking a long time. If using a new enough version of nbdkit, virt-v2v logs should be much less verbose. Security There were no security-related bugs found in this release. Build changes Libguestfs ≥ 1.40 is required, it is now packaged and distributed separately from virt-v2v. For developers you can use a locally built (and not installed) copy of libguestfs. Libvirt is now required to build virt-v2v. Additionally you will require the OCaml bindings to libvirt (https://libvirt.org/ocaml/), although a copy is bundled for now (it will be removed later). (Pino Toscano). Libosinfo is required to build virt-v2v. It is used to query information about guest drivers. (Pino Toscano). Fixes for OCaml ≥ 4.10. The minimum version of OCaml required is still 4.01, but may be increased to 4.05 in future. Test conversions of Debian 9 and Fedora 29 (Pino Toscano). Various fixes to srcdir != builddir (Pino Toscano). Remove gnulib modules not used by virt-v2v (Pino Toscano). Internals When converting SUSE guests, always try to install QXL driver (Mike Latimer). Two new modules (Nbdkit and Nbdkit_sources) factor out generic nbdkit operations and nbdkit source operations respectively. Format Python code to comply with PEP 8 / pycodestyle (Pino Toscano). Tests have been moved to the tests/ subdirectory, and manuals to the docs/ subdirectory.
