+.. note:: This functionality requires to install the **virt-v2v**
(https://www.libguestfs.org/virt-v2v.1.html) binary installed on destination
cluster hosts, as it is not a dependency of the CloudStack agent installed on
the hosts.
+
+As of CS 4.19, it is possible to select a VMware VM from an external or
existing VMware datacenter, convert it to a KVM Virtual Machine and importing
it into an existing KVM cluster.
+
+Requirements on the KVM hosts
+-----------------------------
+
+The CloudStack agent does not install the virt-v2v binary as a dependency, for
which this functionality is not supported by default. To enable this
functionality, the virt-v2v binary must be installed on the destination KVM
hosts where to import the Virtual Machines.
+
+In case virt-v2v is not installed on a KVM host attempting a Virtual Machine
conversion from VMware, the process fails.
+
+The virt-v2v output is logged on the CloudStack agent logs to help
administrators tracking the progress on the Virtual Machines conversion
processes. The verbose mode for virt-v2v can be enabled by adding the following
line to /etc/cloudstack/agent/agent.properties and restart cloudstack-agent:
+
+ ::
+
+ virtv2v.verbose.enabled=true
+
+
+Installing virt-v2v on Ubuntu KVM hosts does not install nbdkit which is
required in the conversion of VMWare VCenter guests. To install it, please
execute:
+
+ ::
+
+ apt install nbdkit
+
+

+
+
+Importing Windows guest VMs from VMware requires installing the virtio drivers
on the hypervisor hosts for the virt-v2v conversion.
+
+On (RH)EL hosts:
+
+ ::
+
+ yum install virtio-win
+
+You can also install the RPM manually from

+For Debian-based distributions:

+
+Selecting the Destination cluster
+---------------------------------
+
+CloudStack administrators must select a KVM cluster to import the VMware
Virtual Machines (left side of the image above). Once a KVM cluster is
selected, the VMware Datacenter selection part is displayed (right side of the
image above).
+
+Selecting the VM from a VMware Datacenter
+-----------------------------------------
+
+CloudStack administrators must select the Source VMware Datacenter:
+
+ - Existing: The existing zones are listed, and for each zone CloudStack
will list if there is any VMware Datacenter associated to it. In case it is, it
can be selected
+ - External: CloudStack allows listing Virtual Machines from a VMware
Datacenter that is not associated to any CloudStack zone. To do so, it needs
the vCenter IP address, the datacenter name, and username and password
credentials to log in the vCenter.
+
+Once the VMware Datacenter is selected, click on List VMware Instances to
display the list of Virtual Machines on the Datacenter
+
+
+Converting and importing a VMware VM
+------------------------------------
+
+.. note:: CloudStack allows importing Running Linux Virtual Machines, but it
is generally recommended that the Virtual Machine to import is powered off and
has been gracefully shutdown before the process starts. In case a Linux VM is
imported while running, it will be converted in "crash consistent" state. For
Windows Virtual Machines, it is not possible to import them while running, it
is mandatory they are shut down gracefully so the filesystem is in a clean
state.
+
+When importing a Virtual Machine from VMware to KVM, CloudStack performs the
following actions:
+
+ - Cloning the Source Virtual Machine on the selected VMware Datacenter:
The source Virtual Machine will be cloned in the original state (running or
stopped for Linux VMs, or stopped for Windows VMs). The recommended state is
the stopped state to prevent data inconsistencies or loss when cloning the
virtual machine.
+ - Converting the Cloned Virtual Machine to KVM using virt-v2v: CloudStack
(or the administrator) selects a running and Enabled KVM host to perform the
conversion from VMware to KVM using **virt-v2v**. If the binary is not
installed, then the host will fail the migration. In case it is installed it
will perform the conversion into a temporary location (which can be selected by
the administrator) to store the converted QCOW2 disks of the virtual machine.
The disks are then moved into t [...]
+
+.. note:: Please consider not restarting the management servers while
importing as it will lead to the interruption of the process and you will need
to start again.
+
+.. note:: As mentioned above, the migration/conversion process uses an
external tool, virt-v2v, which supports most but not all the operating systems
out there (this is true for both the host on which the virt-v2v tool is running
as well as the guest OS of the instances being migrated by the tool). Thus, the
success of the import process will, almost exclusively, depend on the success
of the virt-v2v conversion. In other words, the success will vary based on
factors such as the current O [...]
