Subject: [PATCH 07/12] RHEL: 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.
