This isn't quite the full thing. I think that Pino is also working on replacing the ssh and scp commands in the v2v/input_vmx.ml file with libssh. Without those changes, -i vmx will still issue raw ssh and scp commands, which will use ssh-agent (or keyboard-interactive). The Xen input method doesn't use raw ssh and scp commands, so that one is OK. Rich.

This is built on top of the following patch series: https://www.redhat.com/archives/libguestfs/2019-April/msg00054.html Rich.

v2 was posted here: https://www.redhat.com/archives/libguestfs/2019-July/msg00115.html This also has links to earlier versions. v3: - The 01/11 patch in v2 included a bunch of unnecessary plus one necessary change to how input_password is passed around. I moved the necessary change into the final patch (implementing SSH password authentication) and dropped the rest. - The 01/11

v3 posted here: https://www.redhat.com/archives/libguestfs/2019-July/msg00200.html v4: - The first patch in the v3 series was just a trivial doc whitespace fix so I pushed it. - There's a new patch using the nbdkit-retry-filter. This is not actually upstream in nbdkit but we know enough about how it will work. - Rebased against master and reran the tests. Rich.

The first patch was previously posted here: https://www.redhat.com/archives/libguestfs/2017-December/msg00018.html That patch hasn't changed except that I made the ‘input_transport’ variable type-safe. The second patch adds a significant new mode for liberating data from VMware: the ability to copy VMs over SSH directly from ESXi hypervisors. Although this requires enabling SSH access (a

In previous discussion here: https://www.redhat.com/archives/libguestfs/2017-December/thread.html#00027 we preferred to use ssh://... URLs instead of server:/path. However the URL approach had the problem that the user had to replace spaces with %20 in the paths. However since using space gives an error, we can replace spaces with %20 safely in code, thus removing one obstacle from users.

An alternate solution to: https://www.redhat.com/archives/libguestfs/2017-December/msg00035.html "[PATCH] v2v: -i vmx: Allow ssh URLs to use spaces." is to classify all URLs processed by libguestfs as either ordinary URLs or the special non-standard URLs that we use for things like ‘virt-v2v -i vmx’ and ‘guestfish --add’. For the non-standard URLs, provide a wrapper around

This series (except the last one) changes virt-v2v to use nbdkit for several input modes: -i vmx -it vddk: No change in functionality, as this already uses nbdkit-vddk-plugin, but the code is refactored for the other modes to use. -i libvirtxml: Use nbdkit-curl-plugin instead of qemu curl. vCenter: Use nbdkit-curl-plugin instead of qemu curl. xen: Use nbdkit-ssh-plugin instead of qemu
