similar to: [PATCH] v2v: Implement the --bandwidth* options to control network bandwidth.

The first patch in the old series was pushed a while back, and the last "TEMPORARY"

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.

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

Patch 1 was previously posted here: https://www.redhat.com/archives/libguestfs/2020-June/msg00086.html to handle this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1848862 I was able to observe this bug and for me at least disabling readahead seems to cure it. Patches 2 and 3 are simplifications, removing a now-undocumented feature of virt-v2v-copy-to-local and thus simplifying greatly the

Use -ip instead of --password-file, and various refactorings. It strikes me that we should probably deprecate and eventually remove virt-v2v-copy-to-local. With the introduction of the new SSH and VDDK transports, and with RHEL 5 Xen becoming more irrelevant, it's no longer needed. Rich.

Part 2 fix for: https://bugzilla.redhat.com/show_bug.cgi?id=1842440 Actually this fix on its own should be sufficient, but probably we want the nbdkit fixes too. Note this uses actual OCaml 4.05 features! ("let open" and the Unix.tcgetattr functions). I checked that both features are available on RHEL 7's OCaml. Rich.

These patches add the --password-file parameter, allowing you to pass a single password via a file. https://bugzilla.redhat.com/show_bug.cgi?id=1158526 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

The first commit removes the --dcpath parameter, which just makes the following stuff simpler. Since libvirt has supported getting datacenterpath from VMware since Oct 2015, it's time to drop this hairy parameter. The rest is quite a complicated series of refactorings, followed by a very simple change to add handling of snapshots taken from old virt-v2v. Rich.

Hi, this is a mostly done attempt to switch to ocaml-libvirt, embedding the latest version of it from git. This way, it is possible to improve the way v2v connects to libvirt for both input, and output modules, and interacts with libvirt (e.g. no more virsh calls needed in virt-v2v). As side effect, virt-v2v now requires libvirt, as keeping it optional would create too much burden. I could not

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.

Pass (again) around the libvirt URI string in the various input_libvirt subclasses so that input_libvirt#as_options does not need to connect to print the connection URI. As related change: pass input_conn as non-optional string parameter in classes that require one (all but input_libvirt_other, basically). This avoids the need for extra checks. --- v2v/input_libvirt.ml | 10

Proposed small change to the command line of virt-v2v when specifying that you want VDDK mode. Rich.

Currently virt-v2v has few custom C-based functions for libvirt operations, which are limited in what they do, and there is a lot of duplicated code. Instead, switch to ocaml-libvirt for all the libvirt interaction currently done by the Libvirt_utils module. This has few advantages: - each input & output module now opens a libvirt connection only once, only when needed - no need to pass
