Subject: [PATCH] RHEL 8: v2v: Disable the virt-v2v --in-place option.
This disables the virt-v2v --in-place option which we do not
wish to support in RHEL.
(See commit d0069559a939e47e5f29973ed9a69a13f0b58301).

-=head2 In-place conversion
-
-It is also possible to use virt-v2v in scenarios where a foreign VM
-has already been imported into a KVM-based hypervisor, but still needs
-adjustments in the guest to make it run in the new virtual hardware.
-
-In that case it is assumed that a third-party tool has created the
-target VM in the supported KVM-based hypervisor based on the source VM
-configuration and contents, but using virtual devices more appropriate
-for KVM (e.g. virtio storage and network, etc.).
-
-Then, to make the guest OS boot and run in the changed environment,
-one can use:
-
- virt-v2v -ic qemu:///system converted_vm --in-place
-
-Virt-v2v will analyze the configuration of C<converted_vm> in the
-C<qemu:///system> libvirt instance, and apply various fixups to the
-guest OS configuration to make it match the VM configuration. This
-may include installing virtio drivers, configuring the bootloader, the
-mountpoints, the network interfaces, and so on.
-
-Should an error occur during the operation, virt-v2v exits with an
-error code leaving the VM in an undefined state.
