This describes the major changes since 2.4. Virt-v2v 2.6.0 was released on **8 October 2024**. ### New features You can now use most [**virt-customize**(1)](/virt-customize/1.md) 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). ### Other fixes *-i ova* mode now uses the detected guest firmware, if it's not specified in the OVA metadata (Bella Khizgiyaev). *-o kubevirt* 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). *-o libvirt* mode now includes an \ attribute specifying whether the guest needs BIOS or UEFI to boot. The output of [**virt-v2v-inspector**(1)](/virt-v2v-inspector/1.md) 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:/"` ### Build changes We no longer require external ssh/scp commands for input mode *-i* *vmx*. Instead we use [**nbdkit-ssh-plugin**(1)](/nbdkit-ssh-plugin/1.md) (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 *-o kubevirt* mode. ### Bugs fixed - https://bugzilla.redhat.com/1854275 document that vmx+ssh "-ip" auth doesn't cover ssh / scp shell commands - https://issues.redhat.com/browse/RHEL-21365 Exact string (including the literal \*) should be used when converting guest via vmx by v2v - https://issues.redhat.com/browse/RHEL-28197 Missing firmware type for kubvirt and local output - https://issues.redhat.com/browse/RHEL-33699 Virt-v2v can't convert guest from maintained ESXi hosts with vddk \> 6 - https://issues.redhat.com/browse/RHEL-36591 Migrated Windows VMs require the BLNSVR.exe service to be installed for accurate memory reporting - https://issues.redhat.com/browse/RHEL-45527 Re-add the info about non-interactive authentication back into virt-v2v-input-xen - https://issues.redhat.com/browse/RHEL-45992 Missing OS info for kubevirt output - https://issues.redhat.com/browse/RHEL-49761 qemu-guest-agent not being installed at first boot in Windows Server 2022 - https://issues.redhat.com/browse/RHEL-50731 Allow --mac gw and len fields to be optional - https://issues.redhat.com/browse/RHEL-51169 Uninstalling vmware-tools from windows guest sometimes fails with exit code 1618 or exit code 1603 - https://issues.redhat.com/browse/RHEL-53990 network configuration script does not work for Windows 10 i386 guest - https://issues.redhat.com/browse/RHEL-55763 Re-enable Windows disks post-live migration \[rhel-9.5\] - https://issues.redhat.com/browse/RHEL-55837 Re-enable Windows disks post-live migration \[rhel-9.4.z\] - https://issues.redhat.com/browse/RHEL-56784 window version shows incorrect during converting win11 guest with build number 22631 by virt-v2v - https://issues.redhat.com/browse/RHEL-58065 v2v: The -o kubevirt firmware is not compatible with kubevirt api - https://github.com/libguestfs/virt-v2v/issues/42 rhv-upload broken since Ovirt 4.5, cause Basic Auth has been removed - https://github.com/libguestfs/virt-v2v/issues/45 virt-v2v missing firmware type for kubvirt and local output - https://github.com/libguestfs/virt-v2v/issues/46 Clustername not working when on same Data Center, sharing same storage domains ## SEE ALSO [**virt-v2v**(1)](/virt-v2v/1.md). ## AUTHORS Authors of virt-v2v 2.6: - Andi Chandler - Bella Khizgiyaev - Bella Zhang - Jerry James - liuxiang - Nir Soffer - Richard W.M.
