[Libguestfs] Testing virt-v2v with slow input and rhv-upload keep alive changes

I tested again these patches:
https://listman.redhat.com/archives/libguestfs/2021-December/msg00187.html

(without patch 2: v2v/lib/util.ml: Get disk allocation from input - not needed)

Short version:
import from horribly slow input source works now

Long version:

Patches tested on top current master:

commit 66b0a40406effd1c63c0ab47a271aa5240a77638

    input: Remove incorrect text about passwords in vCenter over HTTPS mode

To test slow input, I used this temporary patch:

diff --git a/input/input_disk.ml b/input/input_disk.ml
index 2b21950a..3dabd3c9 100644
--- a/input/input_disk.ml
+++ b/input/input_disk.ml
@@ -99,6 +99,8 @@ let rec disk_source dir options args =
       match input_format with
       | "raw" ->
          let cmd = Nbdkit.create "file" in
+         Nbdkit.add_filter cmd "delay";
+         Nbdkit.add_arg cmd "delay-extents" "30";
          Nbdkit.add_filter cmd "cow";
          Nbdkit.add_arg cmd "file" disk;
          if Nbdkit.version nbdkit_config >= (1, 22, 0) then

Tested on ovirt 4.5 system, which gives virt-v2v 3600 seconds inactivity_timeout
so it does not close the connection after 60 seconds of inactivity like current
imageio release. To make it behave like release version, I change:

/usr/lib64/python3.6/site-packages/ovirt_imageio/_internal/backends/__init__.py

        # Authorized connections get a longer timeout from the ticket.
        #req.set_connection_timeout(ticket.inactivity_timeout)
        # Simulate imageio 2.3, using hard coded 60 seconds timeout.
        req.set_connection_timeout(60)

Testing import of fedora-35 disk with 3g random data, created based on Richard
instructions posted a few weeks ago.

virt-v2v command:

$ cat ~/v2v/v2v.sh
#!/bin/sh

vm_name=${1:-v2v}
shift

./run virt-v2v \
    -i disk /var/tmp/fedora-35-data.raw \
    -o rhv-upload \
    -oc https://engine.local/ovirt-engine/api \
    -op ~/.config/ovirt/engine.local/password \
    -on $vm_name \
    -os alpine-nfs-01 \
    -of qcow2 \
    -oo rhv-cafile=/etc/pki/vdsm/certs/cacert.pem \
    -oo rhv-cluster=el8 \
    -oo rhv-direct=true \
    "$@"

$ ~/v2v/v2v.sh v2v-delay -v >v2v.log 2>&1
█ 100% [****************************************]
