Virt-v2v-in-place converts a single guest from a foreign hypervisor to run on KVM.  It does this conversion in place, modifying the original disk.

This manual page only documents the differences between this tool and virt-v2v.  You should read virt-v2v(1) first.

 virt-v2v-in-place -i disk filename.img

 virt-v2v-in-place -i libvirt guest

--help

Display help.

-b ...

--bridge ...

See --network below.

--block-driver virtio-blk

--block-driver virtio-scsi

When choosing a block driver for Windows guests, prefer virtio-blk or virtio-scsi.  The default is virtio-blk.

Note this has no effect for Linux guests at the moment.  That may be added in future.

--colors

--colours

Use ANSI colour sequences to colourize messages.  This is the default when the output is a tty.  If the output of the program is redirected to a file, ANSI colour sequences are disabled unless you use this option.

--echo-keys

When prompting for keys and passphrases, virt-v2v normally turns echoing off so you cannot see what you are typing.  If you are not worried about Tempest attacks and there is no one else in the room you can specify this flag to see what you are typing.

Note this options only applies to keys and passphrases for encrypted devices and partitions, not for passwords used to connect to remote servers.

-i disk

Set the input method to disk.

In this mode you can read a virtual machine disk image with no metadata.  virt-v2v tries to guess the best default metadata.  This is usually adequate but you can get finer control (eg. of memory and vCPUs) by using -i libvirtxml instead.  Only guests that use a single disk can be imported this way.

-i libvirt

Set the input method to libvirt.  This is the default.

In this mode you have to specify a libvirt guest name or UUID on the command line.  You may also specify a libvirt connection URI (see -ic).

-i libvirtxml

Set the input method to libvirtxml.

In this mode you have to pass a libvirt XML file on the command line. This file is read in order to get metadata about the source guest (such as its name, amount of memory), and also to locate the input disks.  See "Minimal XML for -i libvirtxml option" below.

-i local

This is the same as -i disk.

-ic libvirtURI

Specify a libvirt connection URI to use when reading the guest.  This is only used when -i libvirt.

Only local libvirt connections to locally stored disks can be used.

-if format

For -i disk only, this specifies the format of the input disk image.  For other input methods you should specify the input format in the metadata.

-io OPTION=VALUE

Set input option(s) related to the current input mode or transport. To display short help on what options are available you can use:

 virt-v2v-in-place -it disk -io "?"

-ip filename

Supply a file containing a password to be used when connecting to the source.  If this is omitted then the input hypervisor may ask for the password interactively.  Note the file should contain the whole password, without any trailing newline, and for security the file should have mode 0600 so that others cannot read it.

--key SELECTOR

Specify a key for LUKS, to automatically open a LUKS device when using the inspection.

--key NAME:key:KEY_STRING

--key UUID:key:KEY_STRING

--key all:key:KEY_STRING

NAME is the libguestfs device name (eg. /dev/sda1).  UUID is the device UUID.  all means try the key against any encrypted device.

Use the specified KEY_STRING as passphrase.

--key NAME:file:FILENAME

--key UUID:file:FILENAME

--key all:file:FILENAME

Read the passphrase from FILENAME.

--key NAME:clevis

--key UUID:clevis

--key all:clevis

Attempt passphrase-less unlocking for the device with Clevis, over the network.  Please refer to "ENCRYPTED DISKS" in guestfs(3) for more information on network-bound disk encryption (NBDE).

Note that if any such option is present on the command line, QEMU user networking will be automatically enabled for the libguestfs appliance.

--keys-from-stdin

Read key or passphrase parameters from stdin.  The default is to try to read passphrases from the user by opening /dev/tty.

If there are multiple encrypted devices then you may need to supply multiple keys on stdin, one per line.

Note --keys-from-stdin only applies to keys and passphrases for encrypted devices and partitions, not for passwords used to connect to remote servers.

--mac aa:bb:cc:dd:ee:ff:network:out

--mac aa:bb:cc:dd:ee:ff:bridge:out

Map source NIC MAC address to a network or bridge.

See "Networks and bridges" in virt-v2v(1).

--mac aa:bb:cc:dd:ee:ff:ip:ipaddr[,gw[,len[,ns,ns,...]]]

Force a particular interface (controlled by its MAC address) to have a static IP address after boot.

The fields in the parameter are: ipaddr is the IP address.  gw is the optional gateway IP address.  len is the subnet mask length (an integer).  The final parameters are zero or more nameserver IP addresses.

This option can be supplied zero or more times.

You only need to use this option for certain broken guests such as Windows which are unable to preserve MAC to static IP address mappings automatically.  You don't need to use it if Windows is using DHCP.  It is currently ignored for Linux guests since they do not have this problem.

--machine-readable

--machine-readable=format

This option is used to make the output more machine friendly when being parsed by other programs.  See "Machine readable output" in virt-v2v(1).

-n in:out

-n out

--network in:out

--network out

-b in:out

-b out

--bridge in:out

--bridge out

Map network (or bridge) called in to network (or bridge) called out.  If no in: prefix is given, all other networks (or bridges) are mapped to out.

See "Networks and bridges" in virt-v2v(1).

--print-source

Print information about the source guest and stop.  This option is useful when you are setting up network and bridge maps. See "Networks and bridges" in virt-v2v(1).

-q

--quiet

This disables progress bars and other unnecessary output.

--root ask

--root single

--root first

--root /dev/sdX

--root /dev/VG/LV

Choose the root filesystem to be converted.

In the case where the virtual machine is dual-boot or multi-boot, or where the VM has other filesystems that look like operating systems, this option can be used to select the root filesystem (a.k.a. C: drive or /) of the operating system that is to be converted.  The Windows Recovery Console, certain attached DVD drives, and bugs in libguestfs inspection heuristics, can make a guest look like a multi-boot operating system.

The default in virt-v2v ≤ 0.7.1 was --root single, which causes virt-v2v to die if a multi-boot operating system is found.

Since virt-v2v ≥ 0.7.2 the default is now --root ask: If the VM is found to be multi-boot, then virt-v2v will stop and list the possible root filesystems and ask the user which to use.  This requires that virt-v2v is run interactively.

--root first means to choose the first root device in the case of a multi-boot operating system.  Since this is a heuristic, it may sometimes choose the wrong one.

You can also name a specific root device, eg. --root /dev/sda2 would mean to use the second partition on the first hard drive.  If the named root device does not exist or was not detected as a root device, then virt-v2v will fail.

Note that there is a bug in grub which prevents it from successfully booting a multiboot system if virtio is enabled.  Grub is only able to boot an operating system from the first virtio disk.  Specifically, /boot must be on the first virtio disk, and it cannot chainload an OS which is not in the first virtio disk.

-v

--verbose

Enable verbose messages for debugging.

-V

--version

Display version number and exit.

--wrap

Wrap error, warning, and informative messages.  This is the default when the output is a tty.  If the output of the program is redirected to a file, wrapping is disabled unless you use this option.

-x

Enable tracing of libguestfs API calls.
