23.2. Converting virtualized guests

Once you have prepared to convert the virtualized guests, use virt-v2v to perform the actual conversions. This section provides the steps to convert the virtualized guests, and the reference table for virt-v2v. Note that conversions are resource intensive processes, involving copying the whole disk image for a virtualized guest. In typical environments, converting a single virtualized guest takes approximately 5-10 minutes.

23.2.1. virt-v2v

virt-v2v converts guests from a foreign hypervisor to run on KVM, managed by libvirt.

virt-v2v -i libvirtxml -op pool --bridge brname vm-name.xml
virt-v2v -op pool --network netname vm-name
virt-v2v -ic esx://esx.example.com/?no_verify=1 -op pool --bridge brname vm-name

Parameters

`-i input`	Specifies the input method to obtain the guest for conversion. The default is libvirt. Supported options are: `libvirt` Guest argument is the name of a libvirt domain. `libvirtxml` Guest argument is the path to an XML file containing a libvirt domain.
`-ic URI`	Specifies the connection to use when using the libvirt input method. If omitted, this defaults to qemu:///system. `virt-v2v` can currently automatically obtain guest storage from local libvirt connections, ESX connections, and connections over SSH. Other types of connection are not supported.
`-o method`	Specifies the output method. If no output method is specified, the default is libvirt. Supported output methods are: `libvirt`, create a libvirt guest. See the -oc and -op options. -op must be specified for the libvirt output method. `rhev`, create a guest on a Red Hat Enterprise Virtualization Export storage domain, which can later be imported using the manager. The -osd or Export storage domain must be specified for the rhev output method.
`-oc URI`	Specifies the libvirt connection to use to create the converted guest. If omitted, this defaults to qemu:///system. Note that virt-v2v must be able to write directly to storage described by this libvirt connection. This makes writing to a remote connection impractical at present.
`-op pool`	Specifies the pool which will be used to create new storage for the converted guest.
`-osd domain`	Specifies the path to an existing Red Hat Enterprise Virtualization Export storage domain. The domain must be in the format <host > <path>; for example, `storage.example.com:/rhev/export`. The nfs export must be mountable and writable by the machine running `virt-v2v`.
`-f file \| --config file`	Load the virt-v2v configuration from file. Defaults to /etc/virt-v2v.conf if it exists.
`-n network \| --network network`	Map all guest bridges or networks which don't have a mapping in the configuration file to the specified network. This option cannot be used in conjunction with --bridge.
`-b bridge \| --bridge bridge`	Map all guest bridges or networks which don't have a mapping in the configuration file to the specified bridge. This option cannot be used in conjunction with --network.
`--help`	Display brief help.
`--version`	Display version number and exit.
